Abstract:
A two-component urethane system. The first component is a hydroxy-terminated polyester polyol containing polymerized residues of phthalic acid and an aliphatic diol having Mn from 60 to 150, and having no more than 15 wt % polymerized residues of aliphatic acids. The second component is an isocyanate-terminated prepolymer containing polymerized residues of diphenyl methane diisocyanate and/or toluene diisocyanate and a glycol or polyol having Mn from 90 to 1000.
