HIGH ACID LARGE PARTICLE SIZE LATEX EMULSIONS, ENHANCED STABILIZATION OF HIGH ACID LARGE PARTICLE SIZE LATEX EMULSIONS, AND COATING COMPOSITIONS FORMED THEREFROM.

摘要

The present invention includes coating compositions and methods for coating substrates using the coating compositions. In some embodiments of the invention, a coating composition is prepared by a method including the steps of a) preparing a latex emulsion by a method including mixing an ethylenically unsaturated monomer component in a carrier to form a monomer emulsion, and reacting the monomer emulsion with an initiator to form the latex emulsion, b) preparing a hydroxyl functional oil graft copolymer by a method including reacting an epoxidized vegetable oil with a hydroxyl functional material in the presence of an acid catalyst to form a hydroxyl functional oil polyol, and reacting the hydroxyl functional oil polyol with an ethylenically unsaturated monomer component in the presence of an initiator to form the hydroxyl functional oil polyol graft copolymer, and c) blending the latex emulsion and a crosslinker then adding the hydroxyl functional oil graft copolymer to form the coating composition. The coating compositions may exhibit no or minimal blush, no or minimal color pick-up, and commercially acceptable adhesion. Substrates coated with the coating compositions of the invention are also disclosed.
