Disclosed is a low formaldehyde emission coating from formaldehyde-based resins that can be applied to a panel for reducing sag and enhancing the strength of the panel. Formaldehyde emissions are reduced by the inclusion of polymeric formaldehyde reactive materials comprising a polyamide scavenger into the coating formula. These formulations are useful as coatings or binders.

Low formaldehyde emission coatings and binders from formaldehyde-based resins

A stain resistant acoustical panel which incorporates within its structure a relatively small quantity of latex which forms an ultra thin coating within the panel such that water may pass through the inner structure of the panel. The panel may further include a primer coating applied to the facing side of the panel to prevent water stains. The coating contains a chelating agent which provides stain resistance to the coated face of the panel. Additionally, the panel may incorporate both latex within its structure and a primer coating comprising a chelating agent.

Stain resistant acoustical panels

The present invention provides for both a composition and method for producing a scratch resistant coating applied to an acoustical panel. The coating primarily comprises binder, filler and mica and is typically applied as a spray. The coating can be characterized as a discontinuous film, whereby sound can pass through the coating to the panel for attenuating sound. The coating is thus enabled to provide a finish and color without compromising the acoustical performance of the substrate. The process primarily comprises combining and mixing the dry components of filler, binder and mica and then combining the same with water and mixing to create an aqueous mix that can be applied to the acoustical panel and dried.
