SILCOLEASE UV CATA 221 UV/EB cationic initiator is a 20% solids solution of diaryl iodonium tetrakis (pentafluoro phenyl) borate salt in reactive diluent providing low toxicity with high reactivity for fast ultraviolet light and electron beam initiated cures at low levels of addition. When blended with the unique chemistry of our SILCOLEASE UV/EB silicone polymer cure systems, and coated using standard solventless coating techniques, these SILCOLEASE UV CATA 221 UV/EB cationic initiator catalyzed formulations are intended for use as release surfaces on a wide selection of papers and films, and against a wide range of adhesive materials. Rapid and stable cure with excellent anchorage to paper and film is achieved by simply passing the coating under high-intensity ultraviolet light (medium pressure mercury vapor bulbs) or under electron beam irradiation.
