WACKER® E155 is an organofunctional silicone blend having improved release and lubricating properties. It is used as an industrial release agent. WACKER® E155 offers cost savings to the end user by providing more effective performance at lower usage levels, by decreasing the number of rejected parts, or by enhancing the life of the end product.
WACKER® E155 provides multiple releases when molding polyurethane or epoxy plastic parts. It may be used as supplied or diluted with a hydrocarbon solvent. The number of releases per application will depend upon the type of plastic and the design of the mold. Usually a small experimental test should be performed prior to any production scale-up.
WACKER® E155 applied to metal cables provides excellent lubricity between the cable and a plastic sheath. It may be applied by dipping, brushing or wiping. The longevity of the cable is greatly enhanced by WACKER® E155.
WACKER® E155 is difficult to remove from parts. Solvent cleaning, sand-blasting and caustic scouring are techniques used to remove WACKER® E155. Where parts must be painted, the end user should assess whether WACKER® E155 will cause a paintability problem.
