High temperature high band heat reflecting coating material and coated article

摘要

A sprayable, non-metallic heat reflecting coating mixture for reflecting heat energy in the frequency range of up to about 5 microns comprises a high temperature zinc compound and a binder substantially transparent to heat energy in the frequency range of up to about 5 microns, in the substantial absence of silica and silica compounds. The mixture and a resulting coating on an article has the capability to reflect an average of at least about 65-85% of heat energy in that frequency range, and stability at temperatures up to about 2000 DEG F. A coating resulting from application of the coating mixture to an article surface has a thickness of greater than about 1 mil up to less than about 10 mils.
