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.

Sag resistant, formaldehyde-free coated fibrous substrate

An applicator head for a vacuum coating system includes a manifold shell having opposing shell plates, each including a conduit attachment coupled to a shell aperture. An applicator manifold is affixed to each shell plate. Each applicator manifold includes two coupled manifold plates, with one including a manifold aperture, and each is affixed to the respective shell plate so that each manifold aperture aligns with the respective shell aperture. An applicator channel is formed between the manifold plates of each applicator manifold, and the applicator channel is fluidically coupled to the manifold aperture of each respective applicator manifold. Each applicator channel forms an applicator port at a leading edge of each respective applicator manifold, and each leading edge is configured to be complementary in shape to an edge of a workpiece to be coated. First and second face plates are disposed over the leading edges of the applicator manifolds.

System for applying a coating to a workpiece

Described herein is a coated building panel having a body and a surface coating atop the body, the surface coating comprising inorganic pigment and a polymeric dispersant comprising a polymer backbone and pendant side chains extending from the polymer backbone; wherein the surface coating comprises a liquid carrier in an amount less than about 1 wt. % based on the total weight of the surface coating.

High solids color face and edge coatings for building panels

The present invention is directed to ceiling panels formed from a porous scrim that is coupled to an acoustical substrate using a scrim attachment system that includes an adhesive.

Scrim attachment system

The present invention is directed to a building panel having a laminate structure, the laminate structure including a topcoat layer comprising a first intumescent composition, a cellulosic veneer layer, an adhesive layer formed from an adhesive composition comprising a second intumescent composition, and a metallic substrate layer and wherein the cellulosic veneer layer is at least partially bonded to the metallic substrate by the adhesive layer. The resulting building panel exhibits superior flame retardancy resulting in a Class A fire rating, according to ASTM E-84.

Fire performance for wood veneer laminated ceiling tile

Described herein is an stain and sag resistant acoustic ceiling panel comprising a porous body formed from mineral and cellulosic fibers having an upper surface opposite a lower surface and at least one side surface extending between the upper surface and the lower surface; a first layer applied to the upper surface, the first layer comprising a hygroscopic component and a hydrophobic component; and a second layer applied to the lower surface, the second layer comprising a hydrophobic component.
