Comments Off on What Is The Shelf Life Of My Assembly Lubricant? (And, Why It Matters)
Remember that temporary assembly lubricant that’s been in your cabinet for years? How do you know if it’s still effective and safe to use? These things are good forever, right?
Absolutely not! Chemical products do indeed have a shelf life. Paying attention to expiration dates helps ensure you are using products at their peak performance levels for optimal results.
What Is Shelf Life?
The shelf life of a product is defined as the “length of time that a commodity may be stored without becoming unfit for use, consumption, or sale.” (https://en.m.wikipedia.org/wiki/Shelf_life). It’s important to note that manufacturers determine the shelf life of a product based upon expectations of normal use and storage. Failure to follow recommended guidelines can limit the expected shelf life of any product.
How Is Shelf Life Determined?
While each product and each manufacturer is unique, shelf life is generally determined by assessing product stability under normal conditions over an extended period of time. Are the active ingredients still effective or have they deteriorated? Chemical composition and anticipated environmental factors both have a role in determining a product’s shelf life.
Product quality can be assessed by determining the concentration of key ingredients. Once the active ingredients of a product begin to degrade, product strength may be diminished.
Environmental factors include temperature, moisture and exposure to air. External contaminants or stresses can also affect product quality.
All of IPC’s products are stamped with a six-digit lot number that signifies the date of manufacture (YY/MM/DD). For example, a lot number of 190301 signifies that the product was manufactured on March 1, 2019. The product expiration date is stamped directly below the lot number.
How Does IPC Calculate Shelf Life?
The shelf life of IPC’s products is determined by observation and testing. Part of the manufacturing process includes retaining a sample of each lot number produced for quality control.
To determine the shelf life of its P-80 Temporary Assembly Lubricants, IPC tests for changes in pH and viscosity. IPC also observes the product for any changes in appearance or separation.
What Other Factors Affect Shelf Life?
The manner in which products are handled by the end user may also influence shelf life. It’s always a good idea to follow the manufacturer’s recommendations for storage and handling. Follow these steps to maintain product quality and get the most out of your lubricant:
Store at recommended temperatures
Properly close containers between use – do not leave bottles uncapped
Do not mix with other chemicals
Use clean tools to avoid introducing contaminants
Do not dilute
Follow manufacturer’s instructions for use
What Happens If I Use My Temporary Assembly Lubricant After The Expiration Date?
Using products beyond their expected expiration date is not recommended. After the expiration date your lubricant may no longer offer the same amount of lubricity which can have an impact on your entire assembly process. If you have questions about whether or not it’s okay to use your product, contact the manufacturer for assistance.

Comments Off on How To Assemble Hoses And Seals With P-80® Temporary Rubber Lubricants
Cars, trucks, buses, locomotives, motorcycles, boats, airplanes, refrigerators, dishwashers, washers and dryers, pumps, construction equipment, conveyor belts, cable assemblies, and machines…What do all of these familiar items have in common?
All of them are composed of countless rubber parts that help them function properly and efficiently. Have you ever considered all of the uses for rubber hoses and seals? Without hoses, seals, grommets, O-rings and so many other rubber parts, most everyday items would leak, fall apart or otherwise malfunction.
Since rubber parts play such an integral role in product function and design, manufacturers have to be careful to assemble them properly to avoid problems down the line. While this sounds simple enough in theory, the reality is that assembling rubber parts can be quite difficult.
The slip-resistant nature of rubber makes it difficult to install, cut, remove or manipulate. Improper part alignment or installation can lead to part failure and safety issues. Repair and installation of rubber parts can take considerable physical effort and time.
Temporary assembly lubricants help solve this problem. When applied to rubber parts, temporary assembly lubricants reduce friction during assembly to make installation easier. Once dry the slipping action goes away and parts stay in place.
What is the best way to apply temporary lubricants to rubber parts? Brushing, sponging, spraying, dunking and dipping are all effective manual application methods. Since each assembly process is unique, the best method is often based on personal preference.
Watch this short video for International Products Corporation’s (IPC) suggestions for assembling hoses and seals with P-80® temporary assembly lubricants:

Comments Off on 10 Things To Know When Choosing An Assembly Lubricant
What is a Lubricant?
A lubricant is a material that reduces the friction between two surfaces making it easier for them to move across each other. Lubricity measures the reduction of friction that results from using a lubricant. A higher percentage of lubricity indicates a greater reduction of force.
Dry force is the amount of force required to insert a part without using a lubricant. Lubricated force is the amount of force required to insert a part after applying a lubricant. A force gauge meter can be used to measure the force (in newtons) needed to insert a part.
A lubricant should be used any time you need to decrease the friction between two surfaces.
10 Things To Know When Choosing An Assembly Lubricant
1. Temporary or Permanent Lubrication?
Some lubricants provide ongoing lubrication to keep parts moving over and over again. Machinery that consists of parts that must continually move or slide across each other will benefit from using a permanent lubricant to ensure they are operating properly.
Other lubricants provide temporary lubrication, reducing the friction between two parts for a short amount of time. After drying, the lubricity provided by a temporary lubricant is gone and the two parts will no longer slide easily across each other. Temporary lubricants are used for assembly and repair applications.
Rubber materials, in particular, are extremely slip-resistant, making them inherently difficult to install, remove, or otherwise manipulate – even when wet. This creates a challenge during the assembly and repair of rubber parts that can result in problems such as ill-fitting, misaligned or damaged parts, rolling O-rings, uneven cuts or worker injury. Temporary assembly lubricants can help prevent these problems.
2. How Much Lubrication Do You Need?
Sometimes you need a lot of lubrication, sometimes just a bit. Different lubricants will reduce friction by varying amounts depending upon their viscosity. Find a formula that is right for your application.
3. What are the Advantages of Temporary Assembly Lubricants?
Reduce Installation Force:
A thin film of lubricant applied to a part fills in any gaps, holes, or spaces between two separate surfaces, allowing them to slide across each other. By reducing the surface tension between the two surfaces, rubber parts can slide into place easily.
Design Parts with Better Tolerances:
When a lubricant is included in the design control process, mated parts can have lower tolerances because the characteristics of the lubricant are considered. Partnering with a lubrication engineer ensures the optimal lubricant is selected before production goes live.
Improve Product Performance:
Improper part alignment can lead to part failure and safety issues. Taking into consideration lubrication properties like dry time, material compatibility, any interfering residue and environmental conditions, will ensure that mated parts will work as anticipated.
Increase Production Rates:
Paring the optimal lubricant with the right application technique speeds up production.
Help to Avoid Worker Injuries:
Assembly lubricants ease the installation process of many parts. An increase in lubricity, even by small amounts, is greatly appreciated by line operators required to maintain strict cycle times. Inferior lubrication quickly leads to fatigue, muscle strain, injuries and lost work time.
4. What is the Dry Time of Your Temporary Lubricant?
Some temporary lubricants dry quickly while others take longer to fully dry.
Quick drying lubricants are frequently used in assembly applications in which the parts undergo pressure testing or movement shortly after assembly. In these cases, it’s important to have the part firmly in place before the next step in the assembly process.
Other assembly applications may take longer or the parts may need to be manipulated a few times before the assembly is complete. In these instances, you may benefit from a slower drying temporary lubricant.
Yet, in other assembly operations, achieving maximum lubrication may be the primary goal and the dry time of the lubricant is less important.
Manufacturers of temporary assembly lubricants should be able to advise you about methods of slightly altering the dry time of their lubricants based upon the amount applied, the method of application, part tolerance, material porosity, and temperature.
5. Can Temporary Lubricants be Used With All Types Of Surfaces?
It’s important to check the compatibility of any chemicals that will come in contact with your parts and equipment. What types of surfaces are they made of? Ask the lubricant manufacturer if their product is compatible with the specific type of rubber, metal and/or plastic found in your parts and equipment.
Lubricants will be absorbed more quickly by porous rubbers, like Buna-N and EPDM, than by plastics and coated rubbers. You may want to choose a quicker drying formula for less porous surfaces.
6. How Will You Apply the Lubricant?
Think about your assembly process and the parts that will need a temporary lubricant. What type of application method will work best for your unique process? Common methods of application include dunking and dipping parts, using brushes, sponges and sprays, and using automated solutions. Make sure the lubricant you choose will work well with the best application method for your unique situation.
7. Can They be Used for Food Manufacturing Equipment?
Food and beverage manufacturing is a highly regulated industry. Therefore, all parts and processes, including any lubricants that are used, must comply with federal regulations and industry standards. Look for specially formulated assembly lubricants that are registered with the NSF as H1 lubricants approved for incidental food contact applications.
8. Are They Safe?
Avoid using lubricants that can cause rubber parts to swell or dry out, like alcohol or petroleum-based products. Look for a product that is compatible with the parts it will come in contact with.
Be sure to also consider the environmental impact of any lubricants you are using. Look for products that are non-hazardous and non-flammable, making them safe for workers and the environment. Many assembly lubricants are biodegradable.
Choose an assembly lubricant that will work well, yet meet all of your safety requirements and federal regulations.
9. Is it Possible to Arrange a Trial?
Many lubricant manufacturers will offer free samples for testing. Testing enables you to run trials for your unique assembly application and choose the product that will best meet your needs.
10. Will the Manufacturer Offer Support?
In addition to their willingness to offer free product samples for testing, look for a supplier that can offer technical guidance and provide a variety of products to solve your assembly requirements. The manufacturer should be able to assist you by providing material compatibility studies, insertion force measurement testing, toxicology reports, regulatory compliance, free product samples, and technical support.
With careful thought and planning, you can find a lubricant that meets all of your specifications. When choosing a lubricant for your assembly application consider the amount of lubricity required, surface compatibility, dry time, application methods, chemical composition and safety of the product.
Comments Off on Everything You Need To Know For Easy O-ring Installation
The O-ring…the little part that plays a big role!
“What are the parts of a car?” Most people will answer with “engine, thermostat, radiator, water pump, battery, alternator, ignition, steering wheel, tires, windows, doors, and seat belts”. Not too many people will mention O-rings. But, O-rings play an integral role in the manufacturing and operation of vehicles of all kinds, as well as most other everyday items such as appliances, pumps, and medical devices.
What Are O-rings?
An O-ring is “a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.” (https://en.wikipedia.org/wiki/O-ring). Like the name implies, an O-ring is a round, rubber ring. O-rings are used to create a tight seal between assembled parts to prevent fluids or air from passing from one part to another. The simple little O-ring is often one of the most important components in finished goods. Without properly installed O-rings leaks and product failures could occur.
Common Installation Problems
O-rings need to be properly installed to do their job and function properly. When installed correctly, O-rings can prevent leaks and add to the service life of the component. Incorrectly installed O-rings may cause leakage resulting in part damage, requiring taking apart and reassembling the component. Some common problems that occur during O-ring installation include tears, twisting and turning, and overstretching.
5 Guidelines for Installing O-rings
Installing O-rings properly at the outset saves time and money in the long run. These installation tips can help you avoid problems that may cause application issues down the road.
Size Matters: Use the right size O-ring for each unique assembly. O-rings that are too small are more prone to tearing and breakage. O-rings that are too large will not provide an adequate seal.
Avoid Overstretching: Each O-ring has a maximum stretch point. Overstretching can cause O-rings to break or tear during assembly or use. Engineers need to ensure that the stretch does not go beyond the maximum elongation of the O-ring. It’s also important to stretch the O-ring evenly, not just on one side or the other. In general, try to stretch the O-ring as little as possible for a tighter fit.
Slide, Don’t Roll: Rolling an O-ring down a shaft for installation leads to spiraling. Spiral wound O-rings cannot be properly installed and their functionality will be limited. This can result in leaks and/or damage to the finished assembly. Sliding the O-ring into place, rather than rolling it, helps avoid spiraling. Using a lubricant helps the O-ring slide easily into place.
Ease O-rings Over Threads: O-rings are often mated with threaded parts. The threads can easily tear the rubber O-rings. Covering the threads with masking tape during installation and using an assembly lubricant can help protect the O-ring from nicks and tears.
Keep Away From Sharp Edges: Some mated parts may also have sharp corners or edges that can damage O-rings. Sometimes these tears are so small they are not visible, resulting in leakage problems later on. Avoid forcing O-rings onto sharp corners and edges. Lubricating the O-rings makes it easier to slide them into place.
Overall, it’s best to avoid using excess force while installing O-rings. Using an assembly lubricant helps ensure that many of the above problems are avoided.
Using a lubricant for O-ring assembly can prevent tears, twisting, pinching, cutting and abrasion of the rubber. A thin film of lubricant applied to the O-ring fills in any gaps, holes, or spaces between the O-ring and the mated part, allowing them to slide across each other. By reducing the surface tension between the two surfaces, the O-ring can slide into place easily, providing a tight fit.
Achieve closer fits by helping to properly seat the O-ring
Aid automated assemblies
Improve product performance and reduce failures
Increase production rates
Help avoid worker injuries
Types of O-ring Lubricants
There are numerous types of lubricants that can be used to install O-rings. Some common choices include soap and water, petroleum distillates, solvents and ester based products. Many traditional choices may cause damage to the rubber O-ring or present safety concerns.
For example, petroleum based products can cause rubber to swell or dry out. Solvents provide poor lubrication, contain high VOCs, may be flammable, and pose possible health risks. Soap and water, while safe, provides inconsistent, nominal lubrication and may reactivate when wet causing problems after assembly.
Ester based lubricants are an ideal solution. They provide excellent reduction in friction, offer temporary lubrication, and are safe for both workers and the environment.
Here is a comparison of some common lubricant choices:
So, how do you choose the right product? Consider these factors:

Comments Off on Solve Hydraulic Line Assembly Problems With P-80® THIX
A worldwide crane manufacturer experienced hydraulic system issues, including contamination, rolled O-rings, leaks, and line shut-downs resulting from numerous false-positive leak detections. Once they began using P-80® THIX for assembly they were able to eliminate false positive hydraulic leaks and contamination, allow easier thread starts and aligned joint assemblies, and achieve torque specifications.
What is P-80® THIX?
P-80 THIX is a biodegradable temporary assembly lubricant that eases installation of tight-fitting rubber and plastic parts by reducing the force needed for insertion. Once assembly is complete, the lubricant dries and the part stays in place. Since THIX is a water-based, thixotropic gel, it stays where it’s put without dripping. THIX does not contain any alcohol or petroleum distillates, so it will not cause rubber to swell, dry out or harden, nor does it contain any hazardous ingredients, making it safe for workers and the environment.
What Was Happening at the Crane Manufacturer’s Plant?
The crane manufacturer was using multiple petroleum-based lubricants for the assembly of hydraulic hoses and thread starts. These lubricants eased the assembly of the hydraulic lines and facilitated thread starts, but, if not applied meticulously, slowed production, increased cost of quality, and increased the amount of rework needed. Over-application of these lubricants caused residue to remain in and around hydraulic lines attracting dirt, contaminating hydraulic systems, fluorescing brightly during black light leak inspections – leading to false positive results, and reducing installation torque over time. When used sparingly, the lubricants caused leaks from rough thread starts, rolled O-rings, friction-related damage, misaligned parts, and low installation torques. They also had frequent line shut-downs because of many false-positive leak detections.
P-80 THIX to the Rescue
A team of design engineers, material engineers and hydraulic line assemblers worked together to find a solution. P-80 THIX was trialed for assembly of hydraulic lines and coating of threads for wet torque starts.
Since THIX is a water-based emulsified thixotropic gel, the volume applied was not critical. Once applied, THIX remained in place regardless of the part’s orientation. The gel as a whole reduced assembly friction by 70% thereby eliminating rolled O-rings and misaligned parts. Installation torques were achieved consistently. After assembly, THIX began to evaporate and lose its lubrication – leaving at most a negligible residue, which will not attract dirt or contaminate the hydraulic system, will not fluoresce, and cannot reduce torque over time.
The crane manufacturer experienced an immediate improvement in cost of quality and on-time delivery metrics. As a result, THIX has been implemented throughout the entire assembly floor and is currently being trialed at other locations worldwide.
Comments Off on How Engineers Choose Rubber Lubricants
A Multi-Disciplinary Engineering Approach to Selecting Assembly Lubricants
Rubber is everywhere! Have you ever stopped to consider how many rubber parts are in your car? Or your dishwasher? Or the airplane flying you away to your dream vacation? So many items that we use every day are composed of thousands of rubber parts of varying size and shape. Each of these components plays an integral role in how that item functions and performs down the road.
Rubber is truly a unique material. It is elastic yet strong, smooth yet tacky, lightweight yet insulates and protects, and soft yet abrasion-resistant. Rubber stretches and compresses, waterproofs no matter its thickness, and remains flexible over a wide temperature range. What’s more amazing is that any of these properties can be optimized by compounding rubber articles using select elastomers, fillers, processing aids, activators and vulcanizing agents. Rubber’s versatility is only limited by one’s imagination. It’s no wonder rubber is so valuable in many industries for an unlimited number of applications including vibration and sound dampening, sealing, electrical and thermal insulation, chemical transport and waterproofing.
Rubber is quite versatile. It can be pushed, pulled, stretched, compressed, or heated to fit in, on, or over anything. Rubber is inherently tacky and can be squeezed into tight areas, but it is naturally slip resistant making it difficult to install, remove or manipulate. It’s not unusual for rubber parts to slip during assembly and not go exactly where they’re intended: an O-ring may get twisted, a heater hose may not be fully inserted, a gap can appear in a waterproof seam. Successful assembly can be tricky. Improper assembly can lead to a multitude of problems including destroyed parts, warranty claims, recalls and worker fatigue or injury.
So, why has rubber installation always seemed to be an afterthought?
Coating rubber parts with a liquid to provide lubrication prior to assembly helps avoid some of the aforementioned problems. Traditionally, lubricant choice was based on convenience. Line workers would find whatever substances were in the plant and use them for rubber assembly. Some common choices were soap and water, alcohol, gasoline, motor oil, petroleum jelly and silicone spray. While these products do provide lubrication, they also introduce health and safety risks and may damage rubber parts.
Enter the Engineers…
To protect product integrity and ensure environmental and worker safety, engineers became involved in the lubricant selection process. Design Engineers, Lubricant Engineers and Ergonomic Engineers all take part in choosing the proper lubricant for each assembly process. Design Engineers are concerned with design tolerance, part breakage, production rates, dry time and material compatibility. Lubricant Engineers are more focused on performance, cost, regulatory compliance and toxicity approval. Ergonomic Engineers remain focused on worker safety and consider factors such as friction and effort reduction, production rates, quality and consistency, and health and safety hazards.
Lubricants Are a Part of the Design Process
As a result of these concerns, lubricants are now included in the initial design phase of many engineered parts. In addition to detailing all facets of the part, material specifications now include the accompanying assembly lubricant and its proper assembly technique. Design stages include a battery of lubricant trials and choices are made based on performance, cost and safety. More and more frequently, water-based lubricants are the product of choice.
The Power of Water-Based Lubricants
A well-formulated oil-in-water emulsion overpowers the low surface energy of rubber. This means the emulsion completely coats the surface without beading up. The oil portion has a natural affinity to the rubber surface and the water is exposed to the environment, facilitating evaporation. Only a thin layer of oil contacts the rubber, an ample volume for successful assembly. The thin coating ensures no residue, temporary lubrication, no compatibility issues and a safe working environment. Once assembled, the water evaporates and the lubrication ceases.
Water-based lubricants can be formulated with different properties making them ideal for essentially any assembly application. Lubricant properties such as viscosity, dry time, biodegradability, compatibility, and surface residue (such as adhesiveness) are all taken into consideration. Engineers can now choose a lubricant tailored exactly to their needs before production begins, eliminating many of the problems that used to occur after assembly.
The lubricant selection process has evolved so that it is now a true collaboration between Design, Lubricant and Ergonomic Engineers. Learn more here about this multi-disciplinary engineering approach to selecting assembly lubricants.
Comments Off on Rubber Lubricants Make Helicopter Maintenance A Breeze
Assembly and repair of helicopters can be difficult. Helicopters are composed of numerous rubber parts, many of which can be hard to install or replace. Rotor blades, shafts, landing skids, control rods, stabilizer bars, pitch levers, blade grips, isolators, bushings, hoses, rotor seals, and tail booms are some of the many helicopter parts that are either composed of rubber or connected with rubber parts.
Unlike traditional airplanes, helicopters have a unique ability to land and take off vertically and to hover in place. A helicopter’s ability to lift and thrust comes from its rotors. These unique properties must be designed to exacting standards, with no room for compromise. High quality materials should be used to ensure that parts are properly installed and assemblies are completed perfectly every time. Reliance on anything other than specialty lubricants, formulated specifically for rubber assembly, creates risks for failure from the onset.
Rubber is naturally slip resistant, making it difficult to work with. Installing, removing or manipulating tight fitting rubber components can be a real challenge. Parts that are improperly aligned or installed may result in performance or safety issues. Temporary assembly lubricants make rubber installation easy.
This diagram shows some of the many helicopter parts that can benefit from using a temporary assembly lubricant for installation.
