Patent No. U.S. 6,896,934 B2
Ferro France-SARL has received a patent for a composition for use in forming an abrasion-resistant easy-to-clean coating on a substrate. The composition includes a mixture of a fluorocarbon polymer component and an enamel-forming component. The enamel-forming component includes at least a first lead-free and cadmium-free glass frit. The first lead-free and cadmium-free glass frit includes from about 30% to about 50% P2O5, from about 15% to about 30% Al2O3, and from 2-40% X2O where X=Na and/or K. The present invention also provides a method of forming an abrasion-resistant easy-to-clean coating on a substrate. The method includes applying the composition to a substrate and sintering the applied composition to fuse an abrasion-resistant easy-to-clean coating to the substrate.
The method can be used to
