Abstract
A composition for improving the adhesion of a paint to a surface, wherein the composition comprises an unsaturated polyester, a modified acrylic resin, a polymerization inhibitor, an aromatic solvent and either divinylbenzene, isopropenyl-2-methyl benzyl isocyanate or an acrylic monomer.
Claims13
A composition which consists essentially of:
- A. from 1.0 to 20.0 weight percent of an unsaturated polyester;
- B. from 1.0 to 30.0 weight percent of a modified acrylic resin;
- C. from 0.0001 to 0.50 weight percent of a polymerization inhibitor;
- D. from 4.0 to 50.0 weight percent of an aromatic solvent;
- and
- E. from 1.0 to 10.0 weight percent of divinylbenzene, isopropenyl-2-methyl benzyl isocyanate or an acrylic monomer,
- wherein a surface treated with the composition provides improved adhesion of a paint to the surface.
