Abstract: A composition and method for protecting pipeline joints is disclosed. A mold covers the exposed pipeline joint. A reaction composition including a polyol, an isocyanate, and an ester, preferably 2,2,4-trimethyl-1,2-pentanediol diisobutyrate, is added to the mold and allowed to react to form a polymer.

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. Additional catalysts, surfactants, flame retardants, and blowing agents may also be used depending upon the desired finished product.

Abstract: A composition and method for consolidating aggregate material is disclosed. The method includes introducing a reaction composition into the aggregate material and allowing it to reach on form a polymer which binds the aggregate together. The composition includes polyol, isocyanate, and ester.
