a global chemical manufacturer

C.A.S.E.

STEPANPOL® aromatic polyester polyols are specifically engineered to meet the diverse and demanding requirements of the C.A.S.E. (Coatings, Adhesives, Sealants and Elastomers) industries.  Stepan has developed a line of high quality polyester polyols that are based on ortho-ester linkages.  By using phthalic anhydride as the building block, Stepan polyols deliver enhanced hydrolytic stability and diverse substrate adhesion while improving abrasion resistance and overall hardness.  The major end uses include liquid and hot melt urethane adhesives, polyurethane dispersions, thermalbreak, cast elastomers, and surface coatings.

Emulsion Polymerization

Experience has proven that choosing the right surfactant for latex manufacture is a critical step. Stepan makes this step easy with the POLYSTEP® line of sulfonates, sulfates, ether sulfates, nonionics, and other specialty surfactants that provide a wide range of surface active properties.

Stepan's surfactant expertise and broad product line enable you to bring quality latex products to the marketplace more efficiently whatever your final application area may be. Stepan's fifty plus years of surfactant experience, coupled with a commitment to a statistically based quality process, assures you of batch-to-batch reproducibility. So remember, POLYSTEP ...cost effective surfactants for consistent latexes... when you reach that critical step.
