Coating of slate with powder polyester paints

Abstract

The production technology of protective decorative coatings for asbestos-cement boards carried out with the use of powder polyester paints of domes tic manufacture is described. The technology was implemented in productive conditions of the Open Joint Stock Company “Krichevcementnoshifer”. The results of testing of asbestos-cement boards with polymeric coatings of blue, green and dark-red colours are presented. The testing was carried out for adhesion, frost- and heat-resistance, abrasive resistance, resistance to variable temperatures, accelerated weathering, water-resistance, colour fastness. It is shown that the complex of performa nce characteristics of the pilot lot of asbestos-cement boards with polymeric coatings corresponds to the requirements of STB 1118-98.
