Lithium Complex Greases – High Temperatures Welcome

High temperatures and extreme pressure environments a part of your business?  No worries, G-MAN® keeps you cool and slick wth its series of Lithium Complex Greases.  G-MAN® Lithium Complex Greases provide strong adherence and mechanical stability, creating powerful resistance to shear and oil separation.  Mechanical stability, often referred to as shear stability, is how effectively the grease remains consistent when subjected to mechanical shear forces.  G-MAN® Lithium Complex greases also have strong water resistance properties and provide anti wear, rust and corrosion prevention.  Lithium complex lubricants are a cost effective lubrication solution to rolling element applications where continuous high temperatures are encountered such as truck wheel bearings, and high speed and strong vibration operations.   Other applications for G-MAN® Lithium Complex thickened greases include oven bearings, automotive components, and marine equipment.  The choice for a lithium complex thickened grease will depend on the operating conditions, temperatures and environment.



Lubricating slow moving gears and gear mesh

Lubricating an enclosed gear, slow moving gear or gear mesh?  When gear drives operate under low rotational velocities, “slow speed wear” can arise. Slow speed wear results in the geometry of the working face of gear teeth changing shape. As a result, the gear can fail.

PolySi® Lubricants’ G-MAN® PST-415 was designed for lubricating slow moving gear drives, operating with high loads and pitch line velocities less than 0.5 m/s.  PST-415 lubricates the gear mesh at these low speeds due to the chemical make-up of the product and its semi fluid state, providing high oxidation resistance with a low friction co-efficient.

PST-415 is a synthetic semi fluid lubricant with extreme pressure and anti-wear additives to control wear, reduce the potential for gear seizure, decrease friction and prevent gear micro-pitting and/or pitting.  PST-415 provides a lubricating film over a greater surface to prevent shearing under extreme loading, and provides good elastomer compatibility, oxidative resistance and corrosion protection.   PST-415 reduces friction loss versus competitive brands.  Applications include lubrication for enclosed gears, solar racking systems, tube mills, rotary kilns, robotics, slow moving motors, spur gears, bevel gears, worm gears, small gears, toothed couplings, power tools and bearings.  G-MAN® keeps gears moving.

Lube Away Car Arm Rest Squeaks

You slide into your new car with your Venti coffee. You are in your zen from your car sound system until you hear that awful squeak that occurs when you put your arm on the door arm rest. Why does your car arm rest squeak? Arm rest squeaks is a common car assembly problem that is caused by two identical materials rubbing together. Innovative car manufacturers can prevent arm rest squeaks by using a high quality lubricant, like PST-15, in its arm rest to prevent it from squeaking.

PST-15 has PFPE and PTFE in it which makes it compatible with almost all materials. The PTFE in PST-15 ensures the lubricant will last the life of the car. PST-15 is odorless and fast drying, two key aspects in a high speed automotive manufacturing environment. PST-15 also has a UV indicator in the lubricant, which enables quality control personnel to ensure the lubricant has been applied. All PolySi® G-MAN® lubricants are manufactured in the USA, reducing the risk of imported products. When you are in the market for a new car, ask your dealer if they are using PST-15, and wipe out arm rest squeaks for good.

Improving grease dispensing accuracy

Does your current grease dispensing mechanism give you accurate deposits without extra maintenance?  Can you apply consistent amounts of lubricant without spending time and money on downtime, rework, and cleanup?  Just a slight change in the flash of a dispensing unit, such as a tip or a syringe, can make grease output differ.  There are 3 methods to increasing grease dispensing accuracy over repeated applications.

Only use high quality dispenser tips 

Selection of a high quality dispenser tip that doesn’t have seams, flash, burrs, contaminants, or a compromised seal is critical to the accuracy of grease deposits.
High quality tips should have package labels with lot numbers for process control and traceability.  Dispenser tip gauges, lengths, and colors should remain consistent from lot-to-lot and style-to-style.

Begin with the lowest pressure setting and select the right type of dispenser tip

The pressure setting on a grease dispensing mechanism will impact its flow and accuracy.  Start with a low setting, such as 10 PSI, and adjust as needed for desired results.  If the outcome differs under the same pressure, a new tip may need to be selected.  There are general purpose tips but that may not be what your application requires.  Tapered tips, and tips with wider openings, different length tips and gauges, will change flow and size.  If you need an exact size deposit, start with a tip that has a diameter half that size for an initial test.

Use Confirmation Methods to measure accuracy

Quantifying accuracy of grease deposits can be critical in part production or production processes.  There are grease flow sensors that can detect the motion of grease passing through it. When located close enough to the dispense point (nozzle), this type of sensor provides a very high degree of confidence that grease did get to the part.   Flow Meters can also be used.  Flow meters are often used in a gear-type device that rotates when grease is forced through the area between the gears. This rotation generates a chain of pulses back to the meter. The rate of the pulses indicate flow velocity. This device should also be placed near the dispenser tip.





Non-Silicone Dielectric Grease Options

Environments where silicone can’t be present, and a dielectric grease is needed, call for a non-silicone dielectric grease to be used.  Non-silicone dielectric greases are similar to silicone dielectric greases but don’t have silicone to ensure material compatibility.  Non-silicone dielectric greases have excellent water washout properties, a wide temperature range, and are compatible with most rubbers and plastics.  Theses greases can be blended with various filling systems to increase effectiveness.  Examples include PST-576 Gel, which is made with a PAO base oil and has a medium consistency.  PST-576 is a non-melting, salt water-resistant gel of high viscosity synthetic hydrocarbon oil with wide temperature capability. It has proven effective in bulk lubrication of automotive under the hood electrical harnesses and paint environments where silicone can’t be present.  Other applications include sliding switches where silicone can’t be present, aerospace applications, and electronics.  PST-589 has similar capabilities but is made with PFPE as its base oil.

PFPE Greases stand up to Harsh Environments

Late for a meeting and the printer isn’t working because the fuser burned out. You cry out, “Why isn’t there a good PFPE grease on the printer fuser?!” PFPEs are a family of fluorinated synthetic fluids that are used to formulate thermo-oxidatively stable lubricants. PFPE Greases are designed for harsh environments, and are used on printers and copiers. PFPE greases can withstands temps from -90°C to +250°C, won’t shrink, crack, swell or discolor, and they resists harsh chemicals, fires and fuel oils. PFPE greases are oxygen compatible and have low volatility, making them ideal in vacuum applications. However, not all PFPE greases are alike. Choosing the correct base oil is key in determining how a PFPE grease will perform in a harsh environment. PFPE greases can be used on rubbers and plastic without any swelling or shrinking, and are often used in office equipment, oil and gas, defense, aerospace and corrugation industries. Tribologists, like those at PolySi® G-MAN™ Lubricants, can help identify the right PFPE grease for a harsh environment application. So the next time the printer fuser goes out, make sure the right G-MAN™ PFPE Fuser Grease is used.

H1 Lubricants Keep the Beer Flowing…

Need lubricant trivia for the next cookout at the neighbor’s house? Try this: What do Anheuser-Busch and Kraft Foods have in common? Answer: They both need H1 Grease in their processing facilities. H1 Lubricants are registered by NSF and based on meeting regulatory requirements including FDA 21 CFR for appropriate use, ingredient and labeling review. G-MAN™ PST-525 is classified as H1 by NSF, meaning it is acceptable as a lubricant with incidental food contact for use in and around food processing areas. H1 compounds may be used on food processing equipment as a protective anti-rust film, as a release agent on gaskets or seals of tank closures, and as a lubricant for machine parts and equipment in locations in which there is a potential exposure of the lubricated part to food. The amount used should be the minimum required to accomplish the desired technical effect on the equipment. H1 lubricant applications include: soda fountains, ice cream machines, ice machines, food belts transferring food, and electrical connections in food environments. In bars and restaurants, H1 is used as a lubricant for beer taps. So next time you have a cold beer on draft, raise a glass to the H1 lube that kept the beer tap flowing.

Lubing Leaky Faucets

The alarm jolts me from my slumber…no wait, it’s my daughter shaking me to tell me the faucet is leaking. Been in my home 13 years, yep, that’s about right for plumbing repairs to start kicking in. Just as we age, O-rings can age and dry out if they don’t have the proper lubricant. When plumbing fixtures and faucets need replacing, existing valve stems are usually removed so that new parts can be installed. The repair work is much smoother if a high quality plumber’s grease is used, like PST-599. PST-599 is used by leading faucet manufacturers for O-rings in faucet cartridges. The reason it is widely used by plumbers is that PST-599 is NSF Certified, Standard 61 Approved for drinking water. Plumber’s grease, like PST-599, outperforms standard greases in preventing water washout and withstanding high temperatures up to 400F degrees. So for that next home plumbing project, be sure to get a high quality plumber’s grease for ease of installation and repair. And remember, G-MAN™ always hits the spot.

Starter Motor Grease- what kind of grease do I need?

Vortex blasts, bitter cold temperatures, snow storms, and cars that don’t start…the joys of winter. These extreme conditions can really cause havoc on starter motors if they are not lubricated with the right starter motor grease. Greases are typically comprised of a base oil, thickening system, and additives. Older technology greases that utilize mineral (crude-based) stocks are becoming less desirable for use in rotating electrical applications, such as starter motors.

Today’s starter motor grease needs to be effective in cold temperatures without thickening, and operate in high temperatures without losing its lubricating base oil. Synthetic and silicone greases have a much wider operating range than conventional greases. PolySi® G-MAN™ Lubricants’ PST-433 Extreme Low Temperature Grease has long been the lubricant chosen by OE’s (original equipment manufacturers) and starter motor rebuilders. G-MAN™’s PST-433 can operate down to -60℃ without any signs of performance failure. When it’s hotter than blazes outside, PST-433 handles 400℉ (204℃) with ease.

So to avoid the car that seems as frozen as the treetops in a winter storm, or an overheated car in the height of summer, be sure you have a high quality lubricant in the starter motor.  And remember, G-MAN™ hits the spot every time.  For more information, please visit

Brake Grease Blues; What is important in a Brake Grease?

During my morning commute to work, I idled up to a stop light only to hear a very nice sports car making a loud SCREECHING noise as it rolled up next to me. Wow, screeching brakes on a hot car really kills a look. That screeching noise was from brakes in need of the right grease. Now that may not sound right, grease on brakes, but it does if you understand how brakes are put together.

Grease never should not come in contact with the braking surface, but there are multiple greases used on brake units. A grease which prevents that awful screeching sound on brakes is G-MAN™ PST-477 by PolySi® Lubricants. G-MAN™ PST-477 is used on the BACK of the brake pad, between the brake pad and the metal shim. The metal shim rubbing on the brake pad is where the awful screeching sound is derived. By putting G-MAN™ PST-477 between the brake pad and the metal shim, noise is eliminated.

Will any grease work on brakes? NO! Your brake grease has to contain a solid lubricant. Brake pads generate extreme heat that can dry out brake grease, so what is left behind is the most important ingredient. G-MAN™ PST-477 has a superior solid lubricant additive package that leaves behind a coating between the shim and the brake pad. The solid lubricant actually burnishes into the metal surface, leaving a protective coating that lubricates the metal surface, and eliminates squeaking.

So, the next time you have a brake job, be sure you use G-MAN™ PST-477 lubricant, because G-MAN™ hits the spot every time.  And remember, G-MAN™ hits the spot every time. For more information, please visit
