Both UV and EB curing must be carried out under oxygen-deficient atmosphere (typically <100 ppm and preferably < 50 ppm residual O2). Components should be well mixed before use. Consult Bluestar Silicones for technical assistance in the selection of appropriate photoinitiators for UV processing.
SILCOLEASE UV POLY 110 UV/EB silicone system is a 100% reactive release coating chemistry based on acrylate-modified silicone copolymer technology. Instant and complete cure is achieved by simply passing the coating under either UV light (with added photoinitiator) or Electron Beam (no photoinitiator required). SILCOLEASE UV POLY 110 silicone polymer can be modified for “easy” and “premium” low release by blending with a release modifier, SILCOLEASE UV RCA 170. Initial and aged releases are very smooth and stable against a wide variety of adhesive materials.
