  WD-70 is a methacryl-functional silane, it is a clear, light and heat sensitive liquid with a faintly sweet odour.
  
  WD-70 is used as adhesion promoter at organic/inorgainc interfaces, as surface modifier(e.g. imparting water repellency, organophilic surface adjustment) or as crosslinking of polymers. It is used as a coupling agent to improve the physical and electrical properties of glass-reinforced and mineral-filled thermosetting resiins under exposure to heat and/or moisture. It is typically employed as a blend additive in resin systems that cure via a free radical mechanism (e.g. polyester, acrylic) and in filled or reinforced thermoplastic polymers, including polyolefins and polyurethanes. It is also used to functionalize resins via radical initiated processes copolymerization or grafting - and to modify surfaces.
