Abstract:
The present invention provides two-component polyurethane compositions that are substantially free of VOCs and comprising, as one component, polyisocyanate compositions and, as a second component, a polyol which is chosen from a cycloaliphatic diol or polyol having a molecular weight of from 100 to 500 and containing one or more 4 to 7 member aliphatic ring and an oligomeric diol or polyol comprising the condensation reaction product of from 30 wt. % to 78 wt. %, based on the total weight of reactants used to make the oligomer, and an acrylic or vinyl emulsion polymer.
