Exterior deep base paint formulation

摘要

The present invention provides increased stain resistance, tannin blocking, adhesion, and various other properties. A composition in accordance with the principles of the present invention comprises at least three binders, nanoparticle pigment, and pigmentary titanium dioxide. In one embodiment, the present invention relates to a coating on a substrate wherein the coating has three binders, nanoparticle metal oxide pigment, and pigmentary titanium dioxide. Various additives may be included to formulate paint as known in the art.

主权项

1. A coated substrate comprising:
a substrate that contains tannins; and a coating on the substrate having: a first binder comprising an acrylic resin, a second binder comprising an acrylic resin, and a third binder comprising an acrylic resin, wherein the first binder is a primer binder in that it is characterized by the ability to prevent bleed-through of tannins from a substrate onto which it is coated and further wherein the second binder and the third binders are topcoat binders in that they are suitable for use in top coating applications and further wherein the first binder, the second binder, and the third binder, comprise self-crosslinking polymers; a pigmentary-sized inorganic pigment comprising titanium dioxide pigment particles; a colorant pigment; and a nanoparticle-sized metal oxide; wherein the coating prevents the bleed-through of tannins from the substrate.
