Paints and Painting Procedures for Solar Energy Collectors,een designed for trapping the solar energy. These collectors are usually made of copper, aluminium, steel or galvanized iron. A solar collector must have very high absorption coefficient for incident solar radiation and very low emissivity in the long wave length region. Means of enhancing the absor

Paints and Painting Procedures for Solar Energy Collectors,g widely adopted in U.S.A. is black chrome. Black paints can economically and efficiently be used up to 65°C and are preferred for solar water heaters. The efficiency of these paints is good as they show a very high absorption coefficient for solar radiation (Table 1). However, they require frequent
