C. into a water-based mold release composition comprising an aqueous emulsion or dispersion of at least one release effective substance and desirably at least one emulsifying agent provides for improved surface quality of the foam product.Also disclosed is a method for preparing a polyurethane foam article in a mold by applying to a mold surface a water-based mold release composition which comprises a release effective system which is in a solid (hardened) state at the mold pour temperature and a liquid state at the demold temperature, pouring a polyurethane foam composition into the mold, curing the foam composition and demolding the foam article. The use of such release effective system in the aqueous mold release composition provides for a reduction in surface defects of the polyurethane foam article.

Abstract: A vinyl acetate-ethylene copolymer emulsion which is about 65-70% solids and has a viscosity of less than about 3,500 is disclosed. The emulsion is prepared by copolymerization of vinyl acetate and ethylene monomers in the presence of a stabilizing system consisting essentially of 2-4 wt %, based on vinyl acetate monomer, of a polyvinyl alcohol having a 100-600 degree of polymerization and 2-4wt %, based on vinyl acetate monomer, of a surfactant. Such emulsions demonstrate an improved speed of set as an adhesive.

Abstract: A method for preparing polyurethane product by the reaction of an organic polyisocyanate with a polyester or polyether polyol in the presence of a catalytically effective amount of a catalyst system consisting essentially of a tertiary amine and 1 to 35 wt %, based on the tertiary amine, of an N-hydroxyalkyl quaternary ammonium carbonylate salt, particularly a quaternary triethylenediamine compound. The preferred quaternary composition is the reaction product of an alkylene oxide in excess of equimolar amount with triethylenediamine in the presence of an acid. The use of such catalyst system advantageously improves the cure time of the urethane reaction, when compared to a system containing solely a tertiary amine, while maintaining the same initiation of the reaction. This advantage can be transferred to a delay in the initiation time while maintaining or shortening the cure time by adjustments in the total amount of the catalyst system used.
