The present invention relates to an acoustical tile that includes a core and a surface treatment. The surface treatment comprises a formaldehyde-free latex binder, the binder including at least one formaldehyde-free biocide. The present invention also provides a process of manufacturing an acoustical tile.

Acoustical tile

The invention, provides a curable, formaldehyde free coating composition comprising a composition comprising a polyacid copolymer crosslinked with a hydroxyl group-containing compound and calcium aluminosilicate powder, panels coated with the coating composition, and a method of coating a panel with the coating composition.

Formaldehyde free coatings for panels

A composition for a slurry for manufacture of acoustical panels includes one or more fillers, one or more binders, water and zinc pyrithione. At least of the fillers and/or binders includes microbial nutrients in an amount of at least 1% based on the dry weight of the acoustical panel. In another embodiment of the invention, acoustical panels include a core having a plurality of opposing surfaces and being at least &#x215b; inches thick. The core comprises the dried product of a slurry of fillers, binders and water. Zinc pyrithione is present in at least one of the core and a coating applied to at least one of the surfaces of the core.

Mold resistant acoustical panel

A paperless gypsum/fiber board with improved surface characteristics has at least one surface comprising a combination of fully hydrated gypsum and reinforcing fiber and has been coated with a primer comprising an aqueous emulsion of a film-forming polymeric material.

Gypsum/fiber board with improved surface characteristics

This disclosure includes a means by which a precoating for a metal plate can be made to withstand stresses imposed upon it and the plate during forming operations such as stretching and drawing by first adding a dry film lubricant to the coating. The lubricant has a softening point as high or higher than the coating.

Internal lubricant which enables epoxy phenolic exterior coated TFS

A metal container comprising a seamless body and an end wall integral therewith and having on at least its interior surface a protective coating which is the reaction product of a citric acid ester utilized as a lubricant in forming the container and an after-applied synthetic resin.
