<p>A hybrid resin composition is described, the composition comprising: A. An A part composition comprising an aliphatic polyfunctional isocyanate compound and a free radical polymerization initiator; and B. A B part composition comprising an ethylenically unsaturated, substantially water-free polyester polyol and a polyurethane catalyst. The A part composition can contain a non-interfering solvent, e.g., styrene, and the B part composition typically has an acid value of 5 or less (based on solids). For outdoor use, the B part composition is preferably free of tertiary hydrogens, ether glycols and terephthalic acid residues.</p> |
