I. Composition and Properties
A-3380 resin is a copolymer of (meth)acrylate monomers and saturated polyesters through a special process, using butyl acetate as a solvent. When used in combination with amino resins, this resin produces coatings with excellent adhesion to metals, superior recoatability and impact resistance, and excellent pigment wetting and dispersion properties.
