Abstract
Coating compositions and methods providing a high build, fast drying, fast hardening non-amine containing aqueous latex binders are provided, wherein the coating composition is applied to a substrate at a wet film thickness to about 15 mils that ensure drying times of less than 10 minutes. The binder requires the use of at least one specific coalescent solvent with both anionic and non-anionic surfactants.
Claims15
An amine free aqueous coating composition comprising:
- an amine free latex binder;
- and
- only one coalescing solvent,
- wherein the amine free latex binder comprises at least one anionic surfactant, a non-ionic surfactant, and a polymer prepared from at least one hard monomer, at least one soft monomer, and at least one acid functional monomer, the amounts of the monomers and the anionic surfactant being:
- (i) 35 to 65% by weight of the at least one hard monomer, based on a total weight of said latex binder;
- (ii) 25 to 55% by weight of the at least one soft monomer, based on the total weight of said latex binder weight;
- (iii) 0.5 to 15% by weight of the at least one acid functional monomer, based on the total weight of said latex binder weight;
- and
- (iv) 0.1% to 4% by weight of the at least one anionic surfactant, based on the total weight of said latex binder weight;
- wherein said latex binder has a glass transition temperature less than 45 degrees Centigrade, and wherein said latex binder is amine free, ammonia free, and ammonium hydroxide free, and has an average particle size diameter consisting of between 210 nanometers and 290 nanometers, and
- wherein said coating composition exhibits a drying time of less than 10 minutes as measured by ASTM test method D711-2010.
