Abstract
A polyurethane foam and a resin composition that may be used to form the polyurethane foam is provided. The resin composition comprises a first ethylene diamine-based polyol having about 100% ethylene oxide capping present in an amount of from 0.5 to 8 parts by weight based on 100 parts by weight of the resin composition, a second polyol, and a physical blowing agent. The polyurethane foam comprises the reaction product of an isocyanate component and the resin composition. A method of forming the polyurethane foam on a substrate, comprising the steps of combining the isocyanate component, the first ethylene diamine-based polyol having about 100% ethylene oxide capping, the second polyol, and the physical blowing agent to form a polyurethane composition is also provided. The polyurethane composition is applied onto the substrate at an ambient temperature of 0° C. or lower to form the polyurethane foam.
