coatings according to the coating effect; topcoats are further divided into flat
coatings, textured coatings and effect pigment coatings according to the coating
effect; flat coatings are further divided into gloss (60°) ≤ 10 GU and gloss (60°) >
10 GU according to the coating gloss.

coatings, topcoats and varnishes according to the coating structure; primers are
further divided into paints and varnishes according to the appearance of the coating
film; intermediate coatings are further divided into flat coatings and textured
