SILCOLEASE POLY 358 may be stored for up to 24 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


Silcolease® POLY 358 is a vinyl functional silicone polymer which when properly formulated and cured produces a crosslinked coating with adhesive release properties. As part of the Optima system, Silcolease® POLY 358 is designed for formulating flexibility to allow reductions in Pt catalyst and more cost effective process conditions. Blending Silcolease® POLY 358 with Silcolease® 8560 provides the means to produce optimized coatings to meet a wide variety of application requirements. To complete the Optima coating system, a hydride functional siloxane crosslinker and platinum catalyst are added to the polymer to facilitate the curing reaction.
