Dow Corning Corporation, a global leader in silicones, silicon-based technology and innovation, as well as specialty lubricants, is launching a new silver-metallic color for Molykote® brand anti-friction coating (AFC) to enhance design options for reducing friction, noise and wear on various automotive components.

Dow Corning, based in Auburn, Mich., U.S.A., is a wholly owned subsidiary of The Dow Chemical Company.

New silver-colored Molykote® D-709 Anti-Friction Coating offers the same high-performance dry-film lubrication advantages as glossy black Molykote® D-708 Anti-Friction Coating, which is proven effective in such applications as brake pad clips, springs and pins. With an appealing silvery metallic finish, Molykote D-709 Anti-Friction Coating can add aesthetically pleasing lubrication for more-visible design components, such as door sliding or locking mechanisms and seating system parts.

Both Molykote D-708 Anti-Friction Coating and Molykote D-709 Anti-Friction Coating can provide a low coefficient of friction on metal parts to reduce noise and wear between metal-to-metal and metal-to-plastic surfaces. They can contribute to lightweighting for added efficiency by eliminating the need for heavier greases and allowing the use of more plastics.

Dry-film AFC technology is helping Dow Corning underscore how Smart Science Drives Mobility Innovation™.

“Unlike conventional ‘wet’ oils and greases, these Molykote® brand Smart Lubrication™ solutions provide a clean, dry boundary lubrication film to optimize surface friction and wear control, reduce noise and roughness for added comfort and smoother operation and aid lightweighting efforts,” said Marjorie Dwane, Dow Corning’s automotive Smart Lubrication global manager.

“Collaboration led to the development of Molykote D-708 AFC for reducing noise and roughness on brake pad clips, and customer requests for a silver-colored option with the same performance and clean processing characteristics for selected applications spurred the development of Molykote D-709 AFC,” she said.

Each of these Molykote anti-friction coatings is formulated with polytetrafluoroethylene (PTFE) solid lubricants in a solvent carrier and resin binder system. Properly applied to pretreated parts with various coating methods, these AFCs provide a clean, dry, slippery film as the lubricating solids fill in surface asperities and smooth roughness. Processing is cleaner with less dust and potential contamination. Precise thicknesses can be applied to meet application requirements.

They can outperform conventional lubricants under various loads, at slow speeds and over a much wider service-temperature range, according to Dow Corning.
