Future Market Orientation And Product Characteristics Of Topcoat Paint

Its film is strong and tough, and it is full of luster, strong adhesion, water resistance, wear resistance, corrosion resistance. It is widely used in high grade wood furniture, also can be used in metal surface. Its main disadvantages are to  blister on damp and paint film powder. Like polyester paint, it has the same problem of yellowing. Polyurethane topcoat paint is a kind of common coatings, which can be divided into two components polyurethane topcoat paint and one component polyurethane topcoat paint. Two-component polyurethane topcoat paint are generally composed of isocyanate prepolymers (also known as low molecular carbamate ester polymers) and hydroxyl resins, commonly known as curing agent components and the main agent components.  This kind of coating is various, and application range is very wide. Also, according to the different that contains hydroxyl group component, it can be divided into acrylic polyurethane, alkyd polyurethane, polyester polyurethane, polyether polyurethane, epoxy polyurethane wait for a variety. Generally, it has good mechanical properties, high solid content, and all aspects of the performance is better. It is a kind of coating variety that has development prospect at present. The main application direction is wood paint, car repair paint, anticorrosive paint, floor paint, electronic paint, special paint and so on. The disadvantage is that the construction process is complex, high requirements for the construction environment, and paint film is easy to produce defects. Single-component polyurethane topcoat paint mainly include polyurethane oil coatings, moisture-cured polyurethane coatings, and closed polyurethane coatings. Its application surface is not as wide as two-component polyurethane topcoat paint, mainly used for floor coating, anticorrosive coating, precoiled material coating, etc. Its overall performance is not as comprehensive as two-component coatings.  Application field and market prospect of polyurethane topcoat paint: The main application directions of polyurethane topcoat paint are wood coatings, automotive repair coatings, anticorrosive coatings, floor coatings, electronic coatings, special coatings, polyurethane waterproof coatings, etc. The disadvantage is that the construction process is complex, high requirements for the construction environment, and paint film is easy to produce defects. Single-component polyurethane topcoat paint mainly include polyurethane oil coatings, moisture-cured polyurethane coatings, and closed polyurethane coatings. Its application surface is not as wide as two-component polyurethane topcoat paint. Polyurethane topcoat paint is widely used. In addition to the above purposes, Acrylic polyurethane can be used as magnetic recording coating, polyester polyurethane can be used as electrical insulating coating, transparent elastic polyurethane can be used as anti-fog coating, etc. It can be used in automobile industry, aviation, ocean, construction, plastic, electromechanical, petrochemical and other fields.
