Problems solved by technology

Most epoxy resins are insoluble in water. At present, most of the coatings used in industry are solvent-based coatings. Conventional solvent-based coatings mostly use aromatic hydrocarbons, esters, alcohols, ketones, etc. as solvents, but organic solvents are flammable and flammable. Explosive, toxic and other shortcomings have brought a lot of inconvenience to storage, transportation and construction, and volatiles are directly discharged into the air, which is relatively polluting to the environment. With the enhancement of people's awareness of environmental protection, new anti-corrosion Green coatings such as corrosive coatings such as powder coatings, solvent-free coatings and water-based coatings have been developed one after another
Due to the harsh curing conditions of powder coatings, its development is limited
