Description

technical field [0001] The invention discloses a resin, specifically a high-performance resin for electrophoretic paint, and belongs to the technical field of resins. Background technique [0002] With the continuous progress of society, people's environmental protection requirements for materials are getting higher and higher. At present, in the application field of traditional industrial coatings in our country, most of them use solvent-based coatings. During the construction and curing process, the volatilization of solvents is easy to cause environmental pollution, and it is flammable and explosive, which brings a lot to transportation, storage, especially construction. insecure. Water-based coatings have many distinctive features and advantages. They do not contain or contain only a small amount of solvents, are non-toxic, environmentally friendly, and safe. Especially after the emergence of electrophoretic coating technology, water-based electrophoretic coatings have ...
