Sodium 2-[(2-aminoethyl)amino]ethanesulphonate CA-95

Description

Ca 95 is a manufacturer and supplier (CAS 34730-59-1), a diaminosulfonic acid chain-extender used in the waterborne polyurethane industry.

The outstanding purity of Hopax's EES-200L provides the benefits of high solid content and excellent stability for waterborne PU dispersions.

Ca 95 works well with all isocyanate and polyol systems, especially with dimethylol propanic acid (DMPA) and dimethylol butyric acid (DMBA). These systems are used for the development of high performance aqueous polyurethanes (PU) used in shoe adhesives and coatings for leather, wood and textiles.
