Misunderstandings in the composition and selection of coatings
Time of Update: 2020-10-09
Coatings generally consist of four basic components: film-forming substances (resins, emulsions), pigments (including body pigments), solvents and additives (additives).
Coatings can be divided into oily coatings, fiber coatings, synthetic coatings and inorance coatings according to the main film-forming substances used in coatings; in our daily life, what are our mistakes when we buy wall paint?
