Document Type and Number:
Japanese Patent JP2008506815
Kind Code:
A
Abstract:
A composition and a method for producing primarily water blown polyurethane foams is provided. The composition uses isocyanate ratios greater than conventional foam system to provide a water blown polyurethane foam suitable for a wide variety of applications including spray roofing, insulation, etc. The preferred composition for preparing a polyurethane foam comprises an isocyanate component and a polyol component, wherein the polyol component preferably comprises a combination of Mannich polyol, polyester polyol, and polyether polyol. Preferably, the composition includes water to act as a blowing agent and a metal salt catalyst to assist in the reaction. Preferably, the isocyanate index is between about 1.2 and about 2.0.
