Water-based paint is a paint that uses water as a solvent or dispersion medium.

Second, the difference between water-based paint and solvent-based paint
The main variety of water-based paint is latex paint, which is mainly composed of four parts: water, emulsion, pigments and fillers and various additives.
It can be seen that the dispersion medium of water-based coatings is water.
In terms of the physical and chemical properties of the coating film, some of the physical and chemical properties of water-based coatings are inferior to solvent-based coatings, such as chemical resistance, weather resistance, and stain resistance.
In terms of the construction environment, water-based coatings generally require construction above 5°C, and solvent-based coatings can also be constructed at 0°C.
On the requirements of the base layer, the water content of the base layer for water-based paint construction should be less than 10%, and the water content of the base layer for solvent-based paint construction should be less than 8%.
