摘要： A silicone pressure sensitive adhesive composition is curable to form a silicone pressure sensitive adhesive. The silicone pressure sensitive adhesive composition can be coated on a substrate and cured to form a protective film. The protective film can be adhered to an anti-fingerprint coating on display glass, such as cover glass for a smartphone.

摘要： A solventless silicone pressure sensitive adhesive composition includes: (A) a polydiorganosiloxane having a monovalent hydrocarbon group with terminal aliphatic unsaturation, (B) a branched polyorganosiloxane having a monovalent hydrocarbon group with terminal aliphatic unsaturation, (C) a polyorganosilicate resin, (D) an olefinic reactive diluent, (E) a polyorganohydrogensiloxane, (F) a hydrosilylation reaction catalyst, and (G) an anchorage additive. This solventless silicone pressure sensitive adhesive composition can be cured to form a pressure sensitive adhesive. When cured on a backing substrate, the resulting adhesive article is useful for protecting electronic devices during fabrication, shipping, and use.
