Abstract
This invention relates to waterborne coatings with enhanced early water blushing resistance, chemical resistance, and adhesion to substrates. These waterborne coatings can be paints, varnishes, and water sealers that offer excellent early water blushing as well as excellent resistance to common household chemicals, such as gasoline, motor oil, brake fluid, transmission fluid, household cleaners, window cleaning fluids, antifreeze, and the like.
Claims18
A waterborne coating composition which is comprised of (1) water;
- (2) an emulsion polymer composition which is comprised of:
- (a) 0.5 weight percent to 15 weight percent of a carbonyl functionalized monomer, (b) 0.1 weight percent to 10 weight percent of a phosphorous containing monomer, (c) at least one ethylenically unsaturated monomer, and (d) 0.05 weight percent to 5 weight percent of a polymerizable surfactant having a terminal allyl amine moiety and (3) at least one coalescing aid.
An emulsion polymer which is comprised of:
- (a) 0.05 weight percent to 8 weight percent of a polymerizable surfactant having a terminal allyl amine moiety, (b) 0.5 weight percent to 20 weight percent of a carbonyl functionalized monomer, (c) 0.1 weight percent to 10 weight percent of a phosphorous containing monomer, and (d) at least one ethylenically unsaturated monomer.
