Patent ID: 8038970

Claim:
A method of modifying the surface of a substrate comprising coating the substrate with a pigment blend comprising a plurality of glass particles selected from the group consisting of glass microspheres having a diameter less than about 50 microns and glass chips having a substantially random geometrical shape and a particle size less than about 50 microns; wherein the glass particles are at least partially coated with a colorless solution of a metal oxy peroxide of the formula MO(00H) x where x is 2, 3, 4, or 6 manufactured by a process comprising forming an aqueous solution of a metal peroxide having the formula M(00H) y , where y is 2, 3, 4, or 6 where such solution is substantially free of other peroxides of the metal, diluting the solution to a metal peroxide concentration of between about 0.5% and about 0.85% by weight of the solution at a pH in the range of from about 4.0 to about 6.5, heating the solution to boiling for a period of from about 1 to about 4 hours, cooling the solution, reheating the solution to boiling for a period of between about 1 and about 2 hours, cooling the solution, reheating the solution to boiling until the peroxide concentration in the solution is in the range of from about 12.5% to about 25% by weight of the initially present metal peroxide, and cooling the resulting clear colorless solution.
