Abstract
A composition for coating a surface comprises an adhesive cementitious material such as a geopolymer, a kaolin, or mixtures thereof, and a filler material. Various filler materials are disclosed, with which the coating composition may be used for thermal mapping, oxygen protection to organic dopants, thermal protection, radiation protection, anti-tamper protection, mechanical abrasion protection, or high emission of electromagnetic radiation. With certain fillers, the coating composition remains thermally stable up to 1200.degree. C., and/or remains thermally operable for brief periods up to about 1400.degree. C. When the coating composition includes a wetting agent, and the filler is between 0.01 micrometer and 10 micrometers in size, the coating composition can take the form of an aqueous spray. With certain fillers, the coating composition can cure at a temperature below 100.degree. C. The coating composition can also be a thick film which provides resistance to cracking and peeling during severe thermal exposure.
