coating composition, substrate, porous substrate, method of depositing on a porous substrate a multilayer composite coating and method for improving the adhesion of a multilayer composite coating system to a porous substrate

摘要

COATING COMPOSITION, SUBSTRATE, POROUS SUBSTRATE, METHOD FOR BANKING A POROUS SUBSTRATE A MULTICAMATED COMPOUND COATING AND METHOD FOR IMPROVING ADHESION OF A MULTICAMATED COMPOSITE COATING SYSTEM. Coating compositions are disclosed which include a film-forming resin, an irradiation curing initiator, a dye, and a diluent. These compositions are substantially free of irradiation curable material. Also disclosed are substrates at least partially coated with such compositions, substrates at least partially coated with a multilayer composite coating comprising at least one coating layer deposited from such compositions, and methods for improving the adhesion of a multilayer composite coating system to such compositions. a porous substrate.
