Material Notes:
Chemical Name: AMMONIUM NONYLPHENOL ETHER SULFATECAS: 68649-55-8Available in: Asia Pacific, Europe, Latin America and North America Applications: RHODAPEX CO-436 can be used to prepare a broad range of commercial emulsion polymers including acrylics, vinyl-acrylics, and styrene-acrylics. Such polymers find application in latex paints, adhesives, paper coatings, and textiles. RHODAPEX CO-436 is particularly useful in the preparation of small particle size emulsion polymers with high water resistance and excellent chemical stability. The versatility of RHODAPEX CO-436 allows it to be used with a wide range of polymerization techniques. Including thermal and redox processes. When properly used in conjunction with other anionic and nonionic surfactants, RHODAPEX CO-436 allows fro the trouble-free commercial production of extremely stable emulsion polymers.Information provided by Rhodia, Rhodia has been acquired by Solvay.
