The Silcolease CATA 221 UV/EB cationic photoinitiator as well as the formulated UV/EB silicone release coating bath will react to ambient sources of ultraviolet light. Keep both cationic initiator and catalyzed bath in opaque, sealed containers for protection from exposure to sources of UV light such as sunlight and fluorescent lighting. Catalyzed bath life should be greater than 24 hours.

“Premium” Release: Smooth and easy for high-speed production, for use against highly aggressive adhesives, typical release force of 5-15 grams/inch;

SILCOLEASE UV POLY 235 low release UV/EB silicone system is a 100% reactive release coating chemistry based on epoxy-silicone copolymer technology. When blended with the unique chemistry of our patented SILCOLEASE CATA 221 UV/EB cationic photoinitiator, and coated using standard solventless coating techniques, the  SILCOLEASE UV POLY 235 system is intended for use as a release surface on a wide selection of papers and films, and against a wide range of adhesive materials. Rapid cure is achieved by simply passing the coating under high-intensity ultraviolet light (medium pressure mercury vapor bulbs) or under electron beam irradiation.
