Wettability of paint to substrate
- 2020-02-21 11:35:37
- admin
The adhesion of the paint film is caused by the mutual attraction between the paint and the polar groups on the surface of the coated substrate, and the mutual attraction between the polar groups is based on the premise that the paint is well wetted on the surface of the coated substrate.Since the wet condition of the coating on the surface of the coated substrate depends on the surface tension of...

The third step in the treatment of water-based paint coated substrates is sealing. The role of the water-based putty is to make the surface of the substrate such as wood not very regular and smooth and minor defects and defects, such as pores, fine cracks, pits, joints and concrete, to reduce the surface roughness and increase the flatness.The requirements for water-based putty are good adhesion a...
