Solar Selective Coating brochure (PDF)

Selective Black, silicone-based paint which collects heat more efficiently than ordinary black paint and resists out gassing to 400F. It is designed to selectively absorb wavelengths with the greatest heat content when used on the metal surfaces of collector panels having glazed covers. It collects heat energy more efficiently than ordinary black paints which emit a significant amount of the energy they absorb. This solar coating allows manufacturers of solar collector panels to achieve selectivity with the economy and ease of application of a paint. The coating also resists out gassing, a major cause of internal fogging of collector covers up to 400F. The coating is designed for spray application and can be applied directly to clean metal surfaces. It dries for handling in about 15 minutes. It is also available in spray cans, and provides a convenient way to touch up electroplated collector panels which may have incurred damage during manufacture, shipping or installation.
