Abstract: A polyurethane catalyst composition comprises N,N'-bis(3-dimethylaminopropyl) urea and 3-dimethylaminopropyl urea in a ratio that can be varied to systematically control flowability, airflow, and force-to-crush physical properties for flexible polyurethane foam to enhance processibility. Increasing the N,N'-bis(3-dimethylaminopropyl) urea to 3-dimethylaminopropyl urea ratio increases the airflow and decreases the force-to-crush values of the foam whereas decreasing the N,N'-bis(3-dimethylaminopropyl) urea to 3-dimethylaminopropyl urea ratio improves the flowability of the foam.

Abstract: Described are aqueous emulsions of active amino groups-displaying epoxide adduct hardeners for curing epoxy resin systems, which are obtained by converting an aqueous solution of a conventional hardener, which contains reactive amino groups and can emulsify the epoxy resin used for adduct formation, under increase of the amine-H-equivalent weight, to an emulsion by mixing with an epoxy resin having a functionality of 1,2-3,5. The viscosity generally is 5 to 40 Pa.s. The values lie on an emulsion viscosity curve with a rising and falling viscosity profile. The hardeners are especially suitable for curing aqueous epoxy resin systems and for application together with epoxy resins as additive for hydraulic binders such as cement.

Abstract: The use of alkoxylated acetylenic diol surfactants in the aqueous synthesis of disperse azo dyes provides a simple process for improving filtration properties of dyestuff. The surfactants may be added prior to the coupling step of the synthesis or prior to heat treatment of the dye slurry. Advantages that are realized by incorporation of the surfactants into the synthesis include decreased filtration time, increased solid content in filter cake, improved washing properties of filter cake, and increased dye yield. In addition, for azo dyes that are synthesized as non-heat-stable crystal modifications, the presence of alkoxylated acetylenic diol surfactants in the dye slurry is effective in promoting the conversion of the dye to the desired thermally stable crystal modification.
