Finish/polish for white leather
Abstract
Abstract A finish/polish for white leather is disclosed which is an aqueous emulsion consisting essentially of (1) 5 to 15 percent by weight of a silicone-acrylate graft copolymer which consists essentially of 20 to 50 percent by weight of a silicone which consists essentially of 88 to 97 mol. percent of dimethylsiloxane units and 3 to 12 mol. percent of methylvinylsiloxane units, and 50 to 80 percent by weight of an acrylate which consists essentially of 58 to 62 percent by weight of ethyl acrylate, 32 to 40 percent by weight of methylmethacrylate and 2 to 6 percent by weight of a compound selected from the group consisting of methacrylic acid, acrylic acid and acrylonitrile, (2) 0.1 to 1.5 percent by weight of a leveling agent, (3) 2 to 4.5 percent by weight of ethylene glycol or a glycol ether, (4) 10 to 20 percent by weight of titanium dioxide, (5) 0 to 10 percent by weight of a wax, and (6) the balance water. The finish/polish can also contain as an optional ingredient from 1 to 3 percent by weight of a siloxane copolymer which consists essentially of 20 to 40 mol. percent of trimethylsiloxane units and 60 to 80 mol. percent of monomethylsiloxane units. The finish/polish of this invention does not tend to rub off and is, therefore, longer lasting, is essentially self-shining needing little or no buffing and provides a smooth finish with little or no evidence of powder or streaking.
