<p>A carboxy- and hydroxy-functional acrylic polymer cross-linked with a polyisocyanate and an amino resin is used as primer for PVC-plastisol. Preferred amino resins are melamine resins, and preferred melamine resins contain imino groups and are alkylated. The primer is particularly useful for steel substrates, more particularly in coil coating.</p> |
