Abstract
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.
