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.

Coating composition and its uses

A composition which provides a coating film having excellent foul releasing property is disclosed. The composition comprises, based on the solid contents of the composition: (A) 20 to 80 weight % of a resin which has a polydialkylsiloxane unit and an epoxy resin unit within its structure; (B) 0.1 to 5 weight % of an amino silane; (C) 0.5 to 5 weight % of a hydrophilic additive; and (D) 0.1 to 5 weight % of a catalyst. A coating, e.g. a coating film, formed from the composition generally has an amphiphilic surface. Thus, the composition is suitable for coatings which prevent both hydrophobic and hydrophilic fouling.
