Abstract
TSSS paint coatings were prepared by using FeMnCuOx pigment in combinations with phenoxy and silicone resins. The spectral selectivity achieved 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 150 degree(s)C but show degradation in 20 days when aged at 180 degree(s)C. Cross-linking and degradation mechanisms of both types of coatings were studied by using FT-IR spectroscopy and termogravimetric measurements, cycling and aging tests.
