Abstract
Described is a solvent-based pigmented coating composition comprising (A) at least one binder comprising at least one acrylate polymer, polyurethane polymer, or a polyester, (B) at least one crosslinking agent selected from the group of blocked polyisocyanates and amino resins, (C) at least one pigment, and (D) at least one organic solvent selected from the group of alkyl acetates or alkyl monoglycol ethers, wherein alkyl is n-pentyl or n-hexyl, and wherein the solids content of the coating composition is at least 35% by weight.
Claims2
A solvent-based pigmented coating composition comprising
- (A) at least one binder comprising at least one acrylate polymer, polyurethane polymer, or polyester,
- (B) at least one crosslinking agent selected from the group of blocked polyisocyanates and amino resins,
- (C) at least one pigment, and
- (D) at least one organic solvent that is n-pentyl acetate, n-pentyl glycol, or n-hexyl glycol,
- wherein the solids content of the coating composition is at least 35% by weight.
A multicoat paint system for a substrate, the system comprising:
- a clearcoat having a dry film thickness in the range of 10 to 40 micrometers;
- a basecoat having a dry film thickness in the range of 3 to 40 micrometers;
- and
- optionally a primer coat and a primer-surfacer coat below the basecoat;
- wherein the basecoat is formed from a solvent-based pigmented coating composition comprising:
- (A) at least one binder comprising at least one acrylate polymer, polyurethane polymer, or polyester,
- (B) at least one crosslinking agent selected from the group of blocked polyisocyanates and amino resins,
- (C) at least one pigment, and
- (D) a first organic solvent that is n-pentyl acetate, n-pentyl glycol, or n-hexyl glycol and a second organic solvent comprising butyl acetate;
- wherein the solids content of the solvent-based pigmented coating composition is at least 35% by weight.
