Abstract
A polyurethane foam formulation for use primarily in sprayed applications has been discovered which provides a smoother than average foam surface. The formulation includes the addition of a primary or secondary mono or polyamine having a hydrogen functionality of two or greater. The compressive strengths of the resultant foams are equivalent to or greater than equivalent formulations without the amines, even though the amines also reduce fluorocarbon loss yielding lower density foams.
