Coating characteristics

In order to meet the requirements of coating manufacturing and construction technology, the synthetic resin for coating needs to have the following characteristics:
① The dispersing medium for coatings has good solubility or dispersibility.
② Has excellent film-forming properties and specific coating film properties, such as gloss, fullness, hardness, elasticity, weather resistance, chemical resistance, etc.
③ It is miscible with other synthetic resins for coatings, so as to modify each other and improve coating performance.
④ The pigment can be properly wetted to facilitate the dispersion of the pigment in the coating.
⑤ Good storage stability.
⑥ The molecular weight is suitable. For example, the molecular weight of synthetic resins for solvent-based cross-linked curing coatings is generally below 104, the molecular weight of synthetic resins for solvent-based non-conversion coatings is from 104 to 105, and the molecular weight for latex coatings is above 105.
Resin for electrodeposition coating should be charged and soluble in water.
