(Summary description)(1) Polyurethane modified paint This coating is also called urethane oil. The drying oils are first transesterified with polyols and then reacted with diisocyanates. Its drying is carried out in the air by double bond oxidation, and the paint dries quickly. Due to the presence of amide group, its wear resistance, alkali resistance and oil resistance are increased. It is suitable for indoor, wood and cement surface coating, but it has poor leveling, easy to yellow, and easy to powder paint. (2) Hydroxyl Curable Polyurethane Coatings Generally, it is a two-component coating, the first component contains isocyanate groups, and the second component generally contains hydroxyl groups. When using, the two components, methyl and second, are mixed and coated to make the isocyanate group react with the hydroxyl group. form a polyurethane polymer. Can be divided into varnish, enamel and primer. It is one of the most varieties of polyurethane coatings. Can be used to make coatings ranging from soft to hard with a bright finish. For metal, cement, wood and rubber, leather and so on.
