Abstract A PIGMENT FOR USE IN ORGANIC RESIN COATING COMPOSITIONS WHICH IS LEAFING GLASS FLAKES. PROTECTIVE COATING AND PAINT COMPOSITIONS CONTAINING THE LEAFING GLASS FLAKES AND ORGANIC RESIN BINDER VEHICLES SUCH AS EPOXY RESIN BINDER VEHICLES FORM A GLASS VENEER ON A SUBSTRATE. AFTER THE COATING COMPOSITION IS APPLIED TO A SUBSTRATE, THE GLASS FLAKES MIGRATE TOWARD AND LEAF AT THE OUTER SURFACE OF THE COATING FORMING LAMINAR LAYERS ADJACENT THE SURFACE OF THE COATING. THE COATINGS AND PAINT COMPOSITIONS CAN BE APPLIED AS BY SPRAYING IN A SINGLE STEP TO NUMEROUS STUBSTRATES TO FORM RELATIVELY THIN COATINGS RANGING, FOR EXAMPLE, FROM 1 TO 10 MILS IN THICKNESS. THE COATING IS BONDED TO THE SURFACE OF AN ARTICLE TO FORM AN IMPERMEABLE GLASS VENEER.
