Abstract: Described herein are methods of forming a VOC and odor-reducing building panel. The methods include providing a substrate; applying a wet-state coating to a major surface of the substrate, the wet-state coating comprising carrier comprising water; and drying the wet-state coating, thereby evaporating at least 95 wt. % of the carrier to form a dry-state coating.

Abstract: The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.

Abstract: The present invention is directed to dirt and anti-microbial resistant compositions and articles that include a powder coating composition formed from a precursor comprising polymeric binder resin, cross-linker, and a blend of liquid carrier and anionic fluorosurfactant. The powder coating may be formed using a liquid-based anionic fluorosurfactant wherein the solids content of the anionic fluorosurfactant within the precursor is from about 13 wt. % to about 28 wt. %.
