WS2 per Process SL-39 and our MoS2 coating are applied at room temperature with no resins or binders and no curing required, while MoS2 per MoS2 per MIL-PRF-46010/AS5272 utilizes resins and binders and requires heat curing.
They are different thicknesses and offer varying degrees of corrosion protection. Please see the technical data on our website or contact us for more information.
This is best left to a qualified design or lubrication engineer and depends on the application of the component.
We can offer advice based on past experience and provide prototype service to allow testing of your components in their actual application.
In any application where long-term lubrication, and extended service life of lubricated components or the prevention of fretting and/or galling is desirable.
WS2 and MoS2 applied with no resins and binders are the best for applications operating in vacuum and have been proven over time by many industries.
In most cases no. WS2 per Process SL-39 has a maximum build up of 0.5 microns and will not affect dimensional tolerances within typical machining limits.
Dry film lubricants can be applied to any ferrous or non ferrous metallic substrate. In some cases, it can be effective on manmade plastics, ceramic etc.
This varies widely depending on the application. Factors such as load, temperature , operating environment, co-lubricants, etc. can greatly increase or decrease the service life of the dry film lubricant.
We typically see a component life of 2-5 times greater than a non-dry film-lubricated component.
A: Yes. WS2 per Process SL-39 and MoS2 will leave a bluish-gray finish which mirrors the original finish.
MoS2 per MIL-PRF-46010/AS5272 will leave a flat black matte finish.
Our Green label grades are designed for hard metals such as Steel, Cast Iron, Hard Bronze, and Stainless Steel.
Our Yellow label grades are designed for soft metals such as Babbitt, Brass Bronze, and Aluminum.
This can vary greatly. Factors include the amount of material that needs to be removed, contact pressure between lapped parts, which grade you are using, etc.
Experimenting with various grades and mixture ratios will determine the best grade for your application. Our test kits are a great way to evaluate which grade is best for your application.
It will depend on your application. Timesaver comes in a powder and is mixed with oil as used, typically 4 parts oil to 1 part timesaver.
A 3 oz jar should be enough to lap the main bearings on a model T, while a 50 lb. pail may be required to lap a large bull gear in the mining industry.
Yes. Because Timesaver Lapping Compounds do not imbed and do not continue to cut, you can lap your components in place.
Care must be taken to protect bearings or other components that are in your system that you do not want abrasives introduced to.
No. Timesaver Lapping Compounds are designed to be mixed with oil or grease only.
It is recommended. However, simply flushing with fresh oil has proven effective. In any case, Timesaver Lapping Compounds will not continue to cut but you need to make sure that any metal that was removed is flushed out of the gear, bearing, bushing, etc.
No. Because Timesaver Lapping Compounds are fast-cutting and then breakdown into an inert material, there is no need to clean your parts prior to changing grades.
