  • spectrally selective paints


In this paper we present some new results for preparation two different types of spectrally selective paints. Solarect Z-LT was prepared due to the demands for preparation of air drying coatings. Solarect Z-WB was a new water-based paint where the use of volatile organic solvents was restricted. In both cases the silicon resins were used as a matrix component. The properties of coatings are a complex combination of properties of the individual components and interfaces between them and polymer and substrate. Different variations for the preparation of final coating over three substrates (aluminium, cooper and stainless steel) were applied in order to obtain maximum solar absorptance and minimum thermal emittance. The durability of coatings has been studied by exposing samples to elevated temperature.
