—is a polyester topcoat designed for outdoor use on HDG. It is based on acid-catalyzed hot-setting melamine cross-linked saturated aromatic polyester. Also contains pigments, extenders, solvents and performance enhancers. The finished coating has medium gloss and demonstrates a good balance between hardness and flexibility and also strong weathering and UV-resistance. The matte textured surface and additional protection against corrosion and mechanical damage make the system with wrinkled polyester enamel a priority choice for metal tiles and other building structures.
