[0002] Any coating that uses water as a solvent or a dispersion medium can be called a water-based coating. Based on the type of binder in the coating, water-based coatings are divided into two categories: natural water-based coatings made of natural substances or minerals and petrochemical water-based coatings made of synthetic resins. Spraying is a coating method that uses a spray gun or a disc atomizer to disperse the spray into uniform and fine droplets with the help of pressure or centrifugal force and apply them to the surface of the object being coated. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivative methods of the above basic spraying forms, such as high-flow low-pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc.
