Abstract
An improved release medium is disclosed for use in the production of decorative laminates by both low or high pressure consolidation. The release medium comprises a self-sustaining release sheet having at least one of its surfaces coated with a composition comprised of mineral particles dispersed in a resinous matrix. The release medium may be used to apply an abrasion-resistant coating to the surface of a decorative laminate during production of the laminate by pressure consolidation.
Claims34
A method for the production of decorative laminates comprising:
- (a) providing a release medium comprised of a self-sustaining release sheet having one and opposing surfaces, at least one of said surfaces of said release sheet including a B-stage cured coating of a composition comprised of abrasion-resistant mineral particles dispersed in a resinous matrix;
- (b) providing a thermosetting resin impregnated decorative sheet and positioning said decorative sheet adjacent a self-sustaining supporting substrate;
- (c) positioning said release medium adjacent said decorative sheet to form an assembly comprised of said release medium, said decorative sheet and said self-sustaining supporting substrate, said release medium being positioned adjacent said decorative sheet in a manner such that an abrasion-resistant coating is formed on the surface of said decorative sheet by transfer of said coating from said release medium by the application of sufficient heat and pressure to said assembly to accomplish said transfer;
- and
- (d) applying sufficient heat and pressure to said assembly to provide a decorative laminate comprised of said decorative sheet and said self-sustaining substrate which decorative sheet includes on the surface thereof an abrasion-resistant coating of a composition comprised of abrasion-resistant mineral particles dispersed in a resinous matrix.
