STEPANPOL® PDP-70

STEPANPOL® PDP-70 is a hybrid aromatic polyester polyol. It is a diethylene glycol-phthalic anhydride-based modified polyester polyol. It exhibits excellent hydrolysis resistance, good thermal stability and low polyol viscosity. It promotes adhesion to a variety of metal and plastic substrates. It offers good hardness/flexibility balance, clarity and low color. It may improve selected physical properties such as tensile strength, modulus and tear strength as well as compatibility with some polyether polyols. It is used in UV curable coatings. STEPANPOL® PDP-70 complies with DSL and TSCA.
