Abstract: A coating composition and method of coating for producing a coating containing at least 21-22% by volume titanium dioxide pigment for developing hiding on a suitable substrate, the coating composition having a pigment volume concentration (PVC) of up to a critical pigment volume concentration (CPVC), preferably a PVC of from about 25% to about 50-60% and more preferably from about 25% to about 45%, and a pigment system including an optional filler and a prime pigment comprising about 70-98% by volume titanium dioxide (TiO.sub.2), preferably a rutile form having a median particle size of about 0.2 microns, and about 2-30% by volume of an aluminum trihydrate (ATH) spacer/extender pigment having a similar median particle size and particle size distribution, preferably substantially the same as for the TiO.sub.2 pigment.

Abstract: Waterborne penetrating coating compositions and a method for applying the coating compositions to wood surfaces are disclosed. The coating compositions include a resin component comprising a first maleinized linseed oil having a low molecular weight in the range of about 1,000 to 3,000, a second maleinized linseed oil having a medium molecular weight in the range of about 4,000 to 8,000 and a medium-long oil length water-reducible alkyd resin, and a solvent component comprising water and propylene glycol tertiary butyl ether (PTB) as a coupling solvent. The coating compositions also preferably include an alkaline solubilizer for neutralizing the resin component and an aliphatic hydrocarbon for controlling evaporation of the solvent component after the coating component is applied to the wood surface.
