Water-based coating is a type of coating that is applied by drenching, i.e., drenching the coating in liquid form evenly on the surface to be coated.

Water-based coating has the following characteristics:

1. Uniform thickness: By drenching, the coating can be evenly distributed on the surface of the object to be coated, forming a relatively uniform thickness.

2. Good adhesion: Water-based coating can effectively adhere to various substrate surfaces, providing good adhesion and durability.

3. One time construction: Compared with traditional brushing or spraying methods, water-based coating can be finished with only one time construction.
