Wacker Wacker® E 155 Release Agent
Categories: Polymer; Thermoset; Silicone

Material Notes: Product description: Release Agent E155 is a unique silicone polymer having improved release and lubricating properties. In most applications, it exceeds the performance of standard silicone fluids. It 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.

Application: 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. 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 E155. E155 is difficult to remove from parts. Solvent cleaning, sand-blasting and caustic scouring are techniques used to remove E155. Where parts must be painted, the end user should assess whether E155 will cause a paintability problem.
