    摘要: The present disclosure relates to a leather coating composition comprising or consisting of a hydrosilylation curable silicone elastomer composition designed to be used as a topcoat for a synthetic leather material, particularly a silicone-based synthetic leather composite material. A silicone coating as a topcoat for a synthetic leather material which is the cured product of the composition, methods of making the topcoat, synthetic leather material utilizing same and uses of the synthetic leather material products are also disclosed. The topcoat is designed to provide a highly crosslinked silicone matrix containing silicon-free organic micro-particles to minimize or at least decrease change in gloss after abrasion. The leather coating composition comprises a hydrosilylation curable silicone elastomer composition, comprising: (i) at least one organopolysiloxane polymer; (ii) a reinforcing silica filler; (iii) a silicone resin cross-linker having terminal (M) groups comprising silicone bonded hydrogen; (iv) a hydrosilylation catalyst; and (v) silicon-free organic microparticles.
