Abstract: The present invention provides two-component aqueous textured layer forming compositions useful for forming flexible top coat layers for sports surfaces. The compositions comprise vulcanized or crosslinked rubber granules, for example, EPDM rubber, a soft:hard acrylic emulsion copolymer blend in a solids weight ratio to vulcanized or crosslinked rubber granule solids that ranges from less than 1:4 to 1:9, a polyalkylene oxide rheology modifier, one or more high boiling alcohols and, as a separate component, an aqueous dispersion of an aliphatic polyisocyanate as well as an epoxy silane. The vulcanized or crosslinked rubber granules may have a sieve particle size of 8 mm or less. The inventive top coat layers have enhanced tensile strength and elongation as well as improved pot life and color stability.

Abstract: Disclosed is a composition and process for making a flexible polyurethane foam from a polyol mixture that contains a copolymer polyol, a polyether polyol having a functionality equal to or greater than 3, an autocatalytic polyol, a hydroxyalkyltriethylenediamine and/or a hydroxytriethylenediamine catalyst, and a tertiary amine catalyst. Said foams have excellent resiliency and low compression sets and are particularly suited for use in low emission automobile seating applications.

Abstract: A method of reducing the number or size of voids in a polyurethane comprises reacting the formulation components in a container having an inner surface, or having a liner that has an inner surface, that has been modified to reduce the shear forces that normally accompany introduction of such components into a container. This is done by modifying the inner container's or container liner's surface by profiling and/or engraving it, or by including as a liner a mesh. The profiling and/or engraving or mesh serves to alter the formulation's flow dynamics such that the polyurethane has fewer and/or smaller voids, i.e., has a more uniform density, than polyurethanes formed without the modification.

Abstract: The present invention describes cyclic amine compounds useful for catalysts for polyurethane form-forming compositions, as well as amine alkoxylates and amine polyether polyols formed form the cyclic amines. The cyclic amine compounds of the invention provide distinct benefits for reaction compositions, methods, and polyurethane foams based on their desirable physical and catalytic properties.

Abstract: The present invention discloses a tertiary amine initiator and polymeric polyol compositions made therefrom useful for making polyurethane polymers, especially polyurethane foams. Said polyurethane polymer foams demonstrate a good balance of mechanical properties, physical properties and low emissions. The tertiary amine initiator is the reaction product of a dihydroxy tertiary amine and a polyhydroxy alcohol, such as the reaction product of N-methyl ethanolamine and glycerine.

Abstract: Cavities are partially or entirely filled with a polymer foam. A flexible, porous mesh tube is introduced into the cavity. The mesh tube has a volume smaller than that of the cavity and has openings. A foamable liquid mixture is introduced into the mesh tube. Despite the presence of the openings, the foamable liquid mixture does not pass through the openings in the mesh tube. The captured liquid composition then expands. As the composition expands, it flows through the openings in the mesh tube and makes contact with the walls of the cavity. After curing, a polymer foam is obtained which adheres to the cavity walls.
