Abstract
The present disclosure relates to a silicone elastomeric coating composition for synthetic leather, particularly silicone-based synthetic leather, a silicone elastomeric coating (e.g., a topcoat) formed as a reaction product of the cure of the coating composition, methods of making the topcoat and synthetic leather utilizing the same and uses of synthetic leather products. The topcoat is designed to provide synthetic leather with an improved abrasion and scratch resistant topcoat.
Claims14
A leather coating composition comprising a hydrosilylation curable silicone elastomer composition comprising:
- (i) one or more polydiorganosiloxane polymer(s) having a viscosity of from 1000 to 500,000 mPa·s at 25° C. and an alkenyl group and/or alkynyl group content of at least 5% by weight of the polymer(s) per molecule;
- (ii) a reinforcing filler;
- (iii) a silicone resin cross-linker having terminal groups comprising silicone bonded hydrogen;
- (iv) a hydrosilylation catalyst;
- (v) a cured silicone powder;
- and
- (vi) an eco-diluent selected from the group of isopentadecane, isohexadecane, isoheptadecane, isooctadecane, isononadecane, a trimethyl terminated polydimethylsiloxane having a viscosity of from 5 to 100 mPa·s at 25° C., and combinations thereof.
