Abstract: A process for preparing alkali silicate—polyisocyanate composites without catalyst separation. The process involves blending a catalyst and a polyisocyanate to form a first component, and blending an alkali silicate and water to form a second component. The first and second components are then mixed together to form a reactive mixture that reacts to form a hardened composite. The progression of the reaction proceeds without excessive foaming, high exotherms, or the release of an offensive odor. Sodium silicate—polyisocyanate composites prepared according to the above process, and a process for using the alkali silicate—polyisocyanate composites to consolidate and seal various types of formations in mining, tunneling, and other construction projects are also disclosed. Any void volume which is capable of receiving a flowable precursor of a composite formulation according to the invention prior to its cure is suitable for treatment according to the present invention.

Abstract: Provided herein are catalyst systems useful for providing polyurethane foam products which exhibit low fogging characteristics while possessing favorable overall physical properties when used as interior components of automobiles and other motorized vehicles.

Abstract: A process, and the product produced thereby, for preparing a polyurea foam which comprises reacting an aliphatic polyamine having an average functionality from about 2 to about 6 wherein about 55 to about 95 percent of the functional groups are primary amine functional groups and about 5 to about 40 percent of the functional groups are primary or secondary hydroxyl groups with a polyisocyanate in the presence of a blowing agent that comprises water. The use of polyether polyamines having primary hydroxyl groups improves the cross-linking characteristics of the polyurea foam.
