Endura - Model Series 400 -Solid / Dry Film Lubricant Coatings

Dry film lubricants can be utilized in applications with extreme temperature ranges (from sub-zero to 1200° F) and resist out-gassing under vacuum for use in the aerospace and military industries. Endura® offers a range of these low friction coatings to satisfy your application requirements.

Our series 400 coating systems are compliant with a wide array of specifications developed by manufacturers and DEMIs in the aerospace, automotive, electronic, medical and plastic molding industries. For instance, we can certify to:

• MIL-L-46010C
• Type III
• MIL-PRF-46010 & MIL-PRF-46147D
• Type I
• Form 1 & 2

At Endura Coatings, we offer solid / dry film lubricant coatings as part of our Series 400 coating solutions. Dry film lubricants can be utilized in applications with extreme temperature ranges (from sub-zero to 1200° F) and resist out-gassing under vacuum for use in the aerospace and military industries. As part of our process, we have 5 steps for these coatings.

Step 1: Temperature controlled removal of contimants on top surface area and sub-surface area.

Step 2: Multi-Faceted Surface Treatments. The contimination removal happens via blastings, passivate, phosphate, chemical etch and ceramic conversion. Anchor points or bonding sites are created for solid and dry film lubricants. And the substrate now has a clean surface

Step 3: Solid and Dry Film Lubricant Deposit.

Step 4: Multi-Step Bonding Process. Vacuum impregnation of solid and dry film lubricants and final cure to bond chemistries to part`s critical working surfaces.

Step 5: Cross section of solid / dry film lubricant matrix.

Coating SpecificationsSuitable Alloys

Solid / Dry Film Lubricant coatings can be applied to most ferrous and non-ferrous metals, rubber and some glass or elastomerics.

Coating Thickness

Coating thicknesses will vary from application to application. Series 400 coating are typically deposited between 0.0002 inch to 0.001 inch per surface. Final film builds will be a function of the specific coating system being applied as well as part mass.

Dry Lubrication

Series 400 dry film lubricant coatings afford excellent self-lubricating surface properties and often serve as more robust product alternatives to traditional lubricants and anti-seizing agents such as oils. They work exceptionally well in mitigating seizing and preventing galling when applied directly to two interacting surfaces. Our 400 Series dry film lubricant coatings provide extremely low coefficient of friction across a wide range of load capacities (some in excess of 250,000 psi), with frictional values as low as 0.02 – 0.04 (per ASTM D2714).

Chemical & Corrosion Resistance

Series 400 coatings offer strong corrosion resistance, and prevent the build up of dust, dirt, debris and other foreign contaminants that may hinder your application process. Additionally, Series 400 coatings are often used as a barrier to prevent galvanic corrosion at the point of contact of two dissimilar metals.

Operating Temperature Range

Our Solid / Dry film lubricant coatings can withstand extreme temperature fluctuations with little to no loss in physical properties. The majority of the coatings found in our 400 Series product family are stable from -400°F temperatures to upwards of 1,200° F.

Critical Processing FactorsBase Metal Surface Requirements

To maximize coating performance, surface contamination and imperfections must be removed prior to coating application to ensure adhesion and performance results. Endura® possesses a variety of means to clean used or heavily contaminated parts and depending on their condition solvents, high heat thermal exposure, blasting medias, or chemical agents may be used to normalize your parts surfaces prior to coating.

How Coatings Are Applied

Depending on the 400 Series coating system being applied, Solid / Dry Film lubricants can be deposited in a variety of ways of which include hand burnishing, line-of-sight sprayed, dipped, or mechanically burnished via a high pressurized blasting operation. Please note that certain Series 400 coatings are migratory in nature and may transfer coating materials onto interfacing surfaces.

Masking

Masking of select surfaces where coating voids are required is available. Endura® works with a variety of mediums to mask surfaces where coating is not desired. Depending on your part’s geometry and surface characteristics painted-on lacquers, pull-plugs, and custom fabricated fixtures may be used to accomplish the aforesaid. In the event masking is required, highlighted or marked prints identifying critical surfaces are extremely helpful in ensuring your parts are processed to spec.
