WS2 – Process SL39

Originally developed for NASA, WS2’s unique, extensively modified lamellar composition of Tungsten Disulfide outperforms other dry-coating lubricants.

Our proprietary process, Process SL39, 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 microns (20 millionths).

 

Benefits & Capabilities

    • Solves problems such as friction, excessive wear, seizing, galling and fretting
    • Overcomes or reduces mechanical lubrication problems, improving performance and extending service life.
    • Eliminates and reduces costly maintenance problems that cause breakdowns and expensive downtime by stopping galling, fretting and friction caused by dissimilar metals and their different hardness factors.
    • Maintains the dimensional integrity of the substrate to within 0.5 microns with no build-up.
    • Withstands loads to 100,000 psi (or load capacity equal to a substrate) and operates in the temperature range of -460°F to 1200°F (-273°C to 650°C).
    • Offers 100% lubricity throughout its texture.
    • Is inert, inorganic, non-toxic, non-distortive, non-corrosive and resistant to most fuels and solvents. It is compatible with and enhances the performance of all oils and greases.
    • Resists carbon buildup due to its extremely low coefficient of friction, less than half that of Graphite, Moly (MoS2) and Teflon.
  • Molecularly bonds to all materials and platings and can only be eliminated by removing the bonded substrate

WS2 Provides

  • Vacuum Compatible Lubrication
  • Maintenance of the dimensional integrity of the substrate to within 0.5 microns (20 millionths) with no build-up
  • Enhancement of the flowing resin due to its low coefficient of friction
  • Reduction in part weight. The part is not packed as tight
  • Release of parts quicker
  • Reduction of pressure and mold wear
  • Lower operation temperatures
  • The capability to produce more parts per hour
  • Reduction of rejects
  • An inert, inorganic, non-toxic, non-distortive, non-corrosive lubrication that is resistant to most fuel solvents
  • Compatibility with an enhancement of all other lubricants and releasing agents
  • A slight delay of corrosion
  • Bonding to all metal or plastic materials and platings and cannot be removed without eliminating the bonded substrate
  • Elimination of material transfer to finished agents
  • Application to No. 1 diamond mirror finish … lens quality
  • 100% lubricity throughout the entire mold
  • Application into slots or holes as small as .060 inch
  • Application to the entire mold surface or only specified inserts, cavities and core pins

 

WS2 Does Not

    • Require heat curing
    • Build upon corners and edges
  • Transfer to finished parts, therefore, does not require secondary cleaning for painting, plating etc.
