Coating composition and its uses

A silicone/polyurethane synthetic leather topcoat composition comprising:

• (i) at least one organopolysiloxane polymer having at least two unsaturated groups per molecule which unsaturated groups are selected from alkenyl groups, alkynyl groups or a mixture thereof;
• having a viscosity of from 100 to 500,000 mPa·s at 25° C.;
• (ii) an inorganic reinforcing filler optionally hydrophobically treated with one or more filler treating agents;
• (iii) a polyorganosiloxane containing at least two or optionally at least three silicon bonded hydrogen (—Si—H) groups per molecule;
• (iv) a hydrosilylation catalyst;
• (v) an adhesion promoter comprising a combination of zirconium acetylacetonate in an amount of from 1 to 5 wt. % of the composition with
• 1,3,5-tris[3-(trimethoxysilyl)propyl]-1,3,5-triazine-2,4,6(1H,3H,5H)-trione, and/or one or more epoxy silanes of the formula
• wherein R5 is an alkyl group having 1 to 6 carbons, R6 is an alkoxy group having 1 to 6 carbons and z=0, 1 or 2, or a mixture thereof, in an amount of from 1 to 6 wt. % of the composition;
• and
• (vi) an eco-solvent;
• and optionally
• (vii) a cured silicone powder.
