PRIMER COMPOSITION FOR SILICONE PRESSURE-SENSITIVE ADHESIVE, LAMINATE AND SILICONE PRESSURE-SENSITIVE ADHESIVE TAPE

摘要

Primer composition for silicone pressure-sensitive adhesives comprises (A) alkenyl-terminated diorganopolysiloxane represented by formula (1) R1R2 2SiO(R2 2SiO)pSiR2 2R1 (1), (B) an organohydrogenpolysiloxane represented by formula (2) (R3 3SiO1/2)k(R3HSiO2/2)m(R3 2SiO2/2)n(R3SiO3/2)p (2), and (C) a hydrosilylation reaction catalyst. Laminate comprises a sheet-form substrate, a primer layer provided by the cure on the sheet-form substrate of the primer composition, and a silicone pressure-sensitive adhesive layer formed on the primer layer. Silicone pressure-sensitive adhesive tape comprising the aforementioned laminate wherein the sheet-form substrate is a plastic film tape.
