Abstract:
1. A sol suitable for surface treatment of a substrate to provide a high temperature sol gel coating, made by mixing in a suitable carrier: a) an effective amount of tetra-propoxyzirconium (TPOZ) for covalently bonding to the substrate; b) an effective amount of an organosilane coupling agent for forming a sol-gel network with the TPOZ; c) an organic acid to catalyze the networking of the organosilane to the TPOZ and to stabilize the rate of hydrolysis of the TPOZ; and d) an effective amount of a pigment to control gloss, color, reflectivity, electrical conductivity, emissivity, or a combination thereof of the substrate when coated with the sol to form a the sol-gel as a thin film finish, wherein the pigment is metal flakes, wherein the flakes include aluminum; and e) an effective amount of aminopropyltrimethoxysilane as a dispersant.
