Description

technical field [0001] The invention relates to the technical field of polyurethane coatings, in particular to an antifouling polyurethane coating. Background technique [0002] The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. It is formed by addition polymerization of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compounds. It has many excellent properties, such as high elasticity, wear resistance, low temperature resistance, solvent resistance and good electrical insulation, so it is very versatile. Polyurethane coatings are currently the most common type of coatings. There are many varieties. The main application directions include wood coatings, automotive repair coatings, anti-corrosion coatings, floor paints, electronic coatings, special coatings, polyurethane waterproof coatings, etc. Although polyurethane coatings have some excellent compr...
