Quartz-Coattm 845-Silver is a new, low expansion, ceramic-metallic formulation that bonds exceptionally well to glass and quartz halogen lamps. This formulation is a single part, water-based, inorganic system that is silver in appearance and enables the coating to absorb and evenly diffuse light at high temperatures. Quartz-Coattm 845-Silver is stable in applications to 2000 oF (1093 8C). Quartz-Coattm 845-Silver is a direct replacement for more conventional aluminum filled, silicone based, solvent-rich coatings. Because 845-Silver is water-based and odorless, it is an ideal replacement for silicone coatings that are flammable and toxic. Quartz-Coattm 845-Silver is formulated to a viscosity range of 400-700 cps and solids content by volume of 42.0%. It is applied easily using conventional pneumatic spray equipment, and the typical dry film thickness is less than 1.0 mils. Curing can be accomplished rapidly in high-speed production systems by ramping the coating to 900-1000 oF for 5 minutes. After curing, the finish is tough and moisture resistant, and no outgassing will occur, even at high temperatures. Quartz-Coattm 845-Silver is available in pint, quart and gallon containers.
