Making keeping cool easier. Reflective properties, heat build-up and durability of coatings with IR-reflective pigments
Heat build-up of coated surfaces due to solar radiation and the resulting temperature increase of interiors are highly undesirable and even dangerous. Therefore, coatings containing special pigments with high IR-reflectance were tested that compare favourably with commercial equivalents. Heat build up in coated surfaces can be reduced by using complex inorganic colour pigments (CICPs) in coatings formulations. CICP dark pigment coatings have a higher solar radiation reflectance index than the same colour commercial coatings used for coating roofs. The CICP pigments were spinels containing mainly Co (Pigment Green 26 and 50) or Fe, Cr (Pigment Brown 33, Pigment Black 30) and hematites containing mainly Fe, Cr (Pigment Brown 29, Pigment Green 17). Aging in atmospheric conditions had no significant impact on the spectral characteristics and, as a result, on the TSR values and heat build-up of the coated surfaces, nor did it deteriorate the decorative properties (colour, gloss). Coatings containing CICPs are resistant both to mechanical stress and corrosion and can be used for coating steel, hot-dip galvanized steel and aluminium substrates. Good adhesion under corrosive conditions renders them widely usable and suitable for use on an extensive range of metal surfaces such as those found on roofs or facades.
