Abstract

Abstract Thickness-sensitive spectrally-selective (TSSS) paint coatings were prepared by using FeMnCuO x pigment in combinations with phenoxy and silicone resins. The spectral selectivity expressed as a ratio between solar absorptance ( a s) and thermal emittance ( e T) was 0.92 0.14 for the first and 0.87 0.18 for the second type of the paint. The surface of phenoxy resin based coatings is characterized by pigment particles protruding from the surface, while silicone based paints exhibit a much smoother surface. Abrasion resistance and adhesion of both types of coatings were enhanced by cross linking the resin binder with diisocyanate hardener. Cured coatings withstand temperatures up to 135°C. Cross-linking and degradation mechanisms of both types of coatings were studied by using FT-IR spectroscopy and thermogravimetric measurements, cycling and ageing tests.
