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.
