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 PS-2402 is an aromatic polyester polyol of exceptional purity and low viscosity.
Rigid isocyanurate boardstock; extender for polyurethane foams, including low-density pour and spray, high-density, and packaging.
Low hydroxyl number for economical isocyanate usage.
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
Aromatic polyester polyol. Used as an extender for polyurethane foams. Possesses very high purity and low viscosity. Improves hydrolytic stability and select physical properties. Possesses low hydroxyl number. Promotes adhesion to metal substrates.
