Title:
CURABLE SILICONE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2017/087351
Kind Code:
A8
Abstract:
A curable silicone composition, the composition includes an organopolysiloxane including: an alkenyl-functional dialkylpolysiloxane with an average of at least two alkenyl groups in each molecule, a degree of polymerization between about 25 and about 10,000, at from about 20 mass % to about 50 mass % of the organopolysiloxane; an alkenyl functional organopolysiloxane resin comprising an Si04/2 unit, an R1
2R2SiO1/2 unit and an R1
3SiO1/2 unit, wherein R1 is C1-10 alkyl and R2 is alkenyl, the alkenyl functional organopolysiloxane resin having the alkenyl group in the range from about 1.0 mass % to about 4.5 mass %, and having an OH content of about 0.2 mass % to about 2.0 mass % and a mass averaged molecular weight of about 2,000 g/mol to about 22,000 g/mol; a crosslinking agent; and a hydrosilylation catalyst in a catalytic quantity.
