Abstract
Abstract REFLECTIVE ALUMINUM SURFACE FOR HIGH POWERED FIXTURES ARE IMPROVED BY APPLYING A NATURAL OR SYNTHETIC HYDROPHILIC COLLOID TO THE SURFACE. USUALLY THE COLLOID IS APPLIED DURING ANODIZING OF THE ALUMINUM SURFACE. IN ONE FORM THE COLLOID IS TANNED OR CROSS-LINKED TO PROVIDE A MORE DURABLE COATING. IN AN ESPECIALLY PREFERRED EMBODIMENT, THE COLLOID AND TANNING AGENT ARE BOTH PRESENT IN THE ANODIZING BATH SO THAT THE COLLOID FORMS A COLLIDATE AND IS TANNED DURING ANODIZING. IN ANY EVENT, THE COLLOID IS CHEMICALLY ABSORBED (CHEMISORBED) AND/OR ELECTROLITICALLY DEPOSITED ON THE SURFACE. THE COATINGS ARE MUCH THINNER, E.G. 1/10 TO 1/5 THE THICKNESS OF NORMAL ANODIZED COATINGS.
