MOLYKOTE® 557 Silicone Dry Film Lubricant Extreme-pressure dry-film lubricant provides exceptional release & lubricating properties Features • Colorless • Nonstaining • No intentional polytetrafluoroethylene (PTFE) or per- and polyfluoroalkyl substances (PFAS) Composition • Waxlike, extreme-pressure lubricant • Supplied as liquid or aerosol; remains as wax film after solvent evaporation Applications MOLYKOTE® 557 Silicone Dry Film Lubricant can be used: • In steel production, where it can increase slitter-blade life, resulting in clean, square edges • In aluminum production, where it can lengthen the life of tools and dies, improve surface finish, lubricate sliding surfaces and surfaces during extruding, deep drawing or spinning • In machine shops, where it can improve surface finishes; extend the life of cutting tools, taps, dies, drills, slitters, and forming tools; reduce wear and reduce stick-slip or metal seizure on bearings, slides, cams adjusting screws, guides and ways • For textile, paper and woodworking industries, where it can reduce wear and friction and reduce product staining from spinning frames, knives, scissors, punches, chain, conveyors or material-handling equipment • For rubber and plastic industries, where it can reduce sticking, pickup or product contamination from handling equipment, knives, conveyors or sliding surfaces Description MOLYKOTE® 557 Silicone Dry Film Lubricant is: • An extreme-pressure lubricant with exceptional release properties for cutting and forming metals, and with lubricating properties for heavily loaded tracks, cams, slides, etc. • Colorless in thin films • Nonstaining to paper or fabrics The solvent evaporates after application, leaving a nearly transparent, thin film. This lubricant film begins to melt at 32°C (90°F) and adheres tenaciously to most surfaces, whether in a solid or fluid state.
