BURNISH AND MAR RESISTANT RESIN FOR CLEAR AND PIGMENTED COATINGS

A method for forming an emulsion polymer includes a step of forming a pre-emulsion by combining a monomer composition with a siloxane-containing composition in water and polymerizing the pre-emulsion by combining the pre-emulsion with a radical initiator in a reactor to form a reaction mixture.

Beschreibung
Zusammenfassung:	A method for forming an emulsion polymer includes a step of forming a pre-emulsion by combining a monomer composition with a siloxane-containing composition in water and polymerizing the pre-emulsion by combining the pre-emulsion with a radical initiator in a reactor to form a reaction mixture. Characteristically, the monomer composition includes one or more monomers selected from the group consisting of (meth)acrylic acid monomers, (meth)acrylic monomers, styrene monomers, vinyl acetate monomers, vinyl ester monomers, and combinations thereof. A paint composition that includes the emulsion polymer is also provided. This invention describes a method to provide excellent burnish and mar resistance while avoiding problems with film appearance that can result from siloxane addition.
