Abstract
The present invention relates to aqueous coating compositions having low gloss for floor polishes, finishes and sealer, as well as wall and floor paints and sealers. These aqueous coating compositions contain one or more water soluble poly(ethylene oxide) resins having the general formula [—CH2CH2O—]n and one or more polymer binders.
Claims14
A coating composition comprising:
- A) 1 to 94.95% by weight of an aqueous solvent comprising water;
- B) 5 to 80% by weight of a polymer binder comprising polymerized units derived from one or more ethylenically unsaturated monomers, an acid-functional residue, and a polyvalent metal ion;
- and
- C) 0.05 to 10% by weight of a water soluble poly(ethylene oxide) resin having the general formula [—CH2CH2O—]n, wherein n is selected to provide a weight average molecular weight of 100,000 to 1,000,000 grams per mole of the water soluble poly(ethylene oxide),
- wherein a single coating of the coating composition provides a 60° gloss of 2.3 to 13.3 and a two-coat burnish resistance of 1.1 to 3.8, wherein the gloss is determined in accordance with ASTM D 1455 (2000) and wherein the burnish resistance is determined as a difference in 85° gloss before and after rubbing with a gauze sponge for 5 cycles.
