Urea-elastomer coatings are produced by the reaction of amino compounds and isocyanates. Developed by the United States in the late 1980s, it has been widely used in the world due to its excellent performance. It is a new, efficient and easy to paint two-component pure polyurea elastomer coating developed after high-solid, powder coating, water-borne coating and uv-curing coating. This kind of high thick film elastomer coating has obvious characteristics: high solid content, green environmental protection, thick and compact and flexible coating, strong adhesion to the substrate, excellent performance of uv resistance, impact resistance, easy to apply. There are many researches on polyurea elastomer coatings at home and abroad.
The results show that when the molar fraction of polyurea content reaches 50%, the self-assembly effect induced by hydrogen bond increases the crystallinity of the copolymer, the corrosion resistance of the coating increases, and the surface energy decreases. Use qtech-412 pure polyurea heavy anticorrosive coating for coating, exposure aging in the artificial ocean and atmosphere environment, infrared spectrum, DSC and other test performance, coating mechanical, uv resistance, structure stability, excellent corrosion resistance.
