These polyester polyols are the primary raw material components used to formulate a variety of polyurethanes. Based on unique ortho-ester linkages, they have proven their ability to enhance performance and reduce your formulation costs. Tests have shown that they:
Improve hydrolytic stability
Improve select physical properties
Promote adhesion to metal substrates
STEPANPOL polyester polyols can be used in coatings formulations. These polyols are low Tg and amorphous (or non crystalline) in their morphology. Due to their ortho structure, they improve hydrolytic stability, tensile strength, and modulus. Some potential elastomers include:
synthesis of urethane prepolymers
synthesis of water borne polyurethane dispersions
synthesis of radiation curable oligomers
formulation of two component urethane coatings
formulation with amino type resins in high solids coatings
polyol cross linker in radiation curable, cationic cure formulations
reactive diluents to increase the solids content of solvent based coatings
epoxy flexibilizers for both coating and molding/potting applications
as modifying resins to reduce the cost of acrylic, alkyd, epoxy, and polyester formulations
STEPANPOL PD-56 is a diethylene glycol-phthalic anhydride-based polyester polyol.
STEPANPOL PD-56 can be used in urethane coatings, adhesives, sealants, and elastomer applications.
It has excellent hydrolysis resistance, very good thermal stability, and primary hydroxyl advantage.
It may promote adhesion to a variety of metal and plastic substrates. In reactive hot melt adhesives,
it provides short open time and good green strength (Lauan to FRP).
