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

A coating composition and process of applying the coating to a substrate are provided herein. The coating composition includes filler particles, binder and a liquid carrier, such as water. The filler particles have an average particle size in the range from about 100 to about 600 microns and preferably in the range from about 200 to about 450 microns. The coating composition comprises from about 15% to about 50% by weight liquid carrier and from about 35% to about 90% by dry solids weight filler particles. The coating composition preserves the acoustic performance characteristics of the substrate to which it is applied, while imparting a textured appearance to the substrate, making the substrate virtually indistinguishable from surrounding panels.

Acoustical panel coating and process of applying same

A process and apparatus for creating an acoustically absorbent porous panel comprises the steps of dispensing cement and fibers with a dry mixer to create a dry mix and aqueous mixing water, surfactant and air with an aqueous mixer to create a foam. The process and apparatus provides for combining and mixing the foam and dry mix in a combining mixer to form a foamed cementitious material comprising on a wet basis about 53% to about 68% by weight cement, about 17% to about 48% by weight water, about 0.05% to about 5% by weight fibers, and about 0.01% to about 10% by weight surfactant. The foamed cementitious material is then dried or cured in a drying chamber. The dried foamed cementitious material may then textured with an embossing roller. The cementitious material provides good acoustical performance with enhanced durability and moisture resistance.

Method for producing an inorganic foam structure for use as a durable acoustical panel

Phenolic foam which can be used as insulation is a foamed phenol-formaldehyde resole resin which contains a peptide, a proteinaceous material, cysteine, glutamic acid, glycine, isoleucine, leucine, lysine, phenylalanine, serine, tryptophan, or mixtures thereof at an amount effective to reduce emission of free formaldehyde from the foamed resin.
