SILCOLEASE POLY 356 may be stored for up to 12 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


Silcolease® POLY 356 polymer is a vinyl functional silicone fluid which, when properly catalyzed and cured, gives a semi-flexible crosslinked coating with premium release properties. As part of the Optima system, Silcolease® POLY 356 is designed for formulating flexibility to allow reduction in Pt catalyst and more cost effective process conditions. The simplest Silcolease® POLY 356 release coating system comprises the vinyl silicone polymer, a methyl hydrogen siloxane crosslinker and a platinum catalyst. The resulting addition reaction is very rapid, and, therefore, an inhibitor is included to provide bath stability at ambient conditions while allowing rapid cures at elevated temperatures.
