Silcolease® UV POLY 235 low release UV/EB silicone system is a 100% reactive release coating chemistry based on epoxy-silicone copolymer technology.
•Fast cure response •Room temperature processing •Silicone-epoxy chemistry •Highly efficient photo-initiator •Functional adhesion promotion •Optional release modifiers •Low sensitivity to longer wave length radiation •No oxygen inhibition •Process simplicity •High production rates •Processing of thermally sensitive substrates •Moisture retention in paper •Stable aged release •Low levels of silicone extractables •Compatibility with a wide range of substrates •Excellent anchorage •Targeting of release force requirements •Long catalyzed bath life in ambient light •Inerting is NOT required
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; Components Parts (by weight • Silcolease® UV POLY 235 UV/EB Silicone Polymer 100.0 100.0 • Silcolease® CATA 221 UV/EB Cationic Initiator 2.0 (UV cure) 0.75-1.00 (EB cure)
