Guide to selection of Anti-Friction Coatings

Dow Corning Anti-Friction Coatings

Selection of Anti-Friction Coatings
Molykote Anti-Friction Coatings typically contain MoS2 (molybdenum disulfide), graphite or PTFE lubricating solids. Depending on your lubrication need, precise formulations can be engineered with these or other lubricating solids to provide customized options that meet your exact requirements.

Product selection depends on service requirements, the desired coating method and specific advantages for different applications.From selecting the right formulation for your application needs to identifying the proper coating methods, you can rely on Molykote experts for help.

The Coating Process

To ensure the effectiveness and full service life of Molykote Anti-Friction Coatings, a proper coating process must be followed. Surface pretreatment is important. Depending on the material, this involves degreasing, sandblasting, phosphating, anodizing, acid washing or other type of surface pretreatment.

Once the pretreated parts materials dry, various methods can be used to apply an anti-friction coating. Following application, the coating requires drying and curing to bind the lubricating solids to the parts. This can vary from as little as three minutes with air drying to as long as one hour with oven curing.

Advantages of Anti-Friction Coatings
Molykote Anti-Friction Coatings are bonded, dry-film lubricants that provide superior lubrication in harsh operating conditions and environmental extremes. They are economical to apply, long lasting and valued in uses where other lubricants fail. Compared to typical lubricating pastes and greases, Molykote Anti-Friction Coatings have a number of advantages.

They provide:
• Dry, clean lubrication unaffected by dust, dirt and moisture;
• Lifetime lubrication without aging, evaporation or oxidation;
• Rust prevention without surface treatments like galvanizing;
• Nonflammable, non-staining protection on metals and plastics;
• Controlled film thickness for exact load-bearing capabilities; and,
• Fully effective lubrication even after prolonged shutdown.

How Anti-Friction Coatings Work
Molykote Anti-Friction Coatings have solid lubricant particles dispersed in carefully selected blends of resin and solvents. The volume concentration of lubricants and choice of raw materials are important for the lubricating and corrosion-protection properties. Once applied to a metal or plastic, these paint-like solutions bond to the coated surface and provide a slippery lubricating film that is dry and clean. The film covers all surface roughness and optimizes metal-to-metal, metal-to-plastic or plastic-to-plastic friction even under extreme loads and working conditions.

The Molykote® brand is designed and engineered to solve your difficult lubrication related problems and save energy by reducing friction and wear. Molykote® products are distributed by Parla Tech in iran .
