Material Notes:
WS2's unique, extensively modified lamellar composition of tungsten disulfide results in a high performance dry coating lubricant. A pressurized air application processes impinges a dry metallic coating without heat, binders, or adhesives. The lubricant coating bonds instantly to any metal or resin substrate with a thickness of 0.5 µm (0.020 mil).Benefits and Capabilities of WS2:Solves problems such as friction, excessive wear, seizing, galling, and fretting.Overcomes or reduces mechanical lubrication problems, improving performance and service life.Maintains the dimensional integrity of the substrate to within 0.5 µm with no build-upWithstands up to 300,000 psi (>2000 MPa) or load capacity of substrate.Offers 100% lubricity throughout its textureIs inert, non-toxic, non-distortive, non-corrosive, and resistant to most fuels and solvents.Information provided by BryCoat, Inc.
