Abstract
The present invention relates to a composition comprising an aqueous dispersion of acrylic polymer particles; paraffin wax; graphite particles; and extender particles. The composition is useful for making coatings with low water pickup for liquid applied sound damping applications.
Claims10
A composition comprising an aqueous dispersion of acrylic polymer particles having a z-average particle size in the range of from 50 nm to 500 nm, and a calculated Tg in the range of from −25° C. to 30° C.;
- paraffin wax;
- extender particles;
- and a rheology modifier;
- wherein the pigment volume concentration of the composition is in the range of from 40 to 70;
- and wherein the composition has a Brookfield viscosity in the range of from 200,000 cP to 20,000,000 cP when not under shear conditions.
