STEPANPOL® AROMATIC POLYESTER POLYOLS
STEPANPOL aromatic polyester polyols are a series of difunctional materials for use in polyurethane and polyurethane-modified polyisocyanurate polymers. They are utilized in rigid and flexible foams, and in coatings, adhesives, sealants, and elastomers (C.A.S.E.) applications. Stepan's basic position in phthalic anhydride and extensive experience in polyester polyol production result in several advantages for STEPANPOL polyols:
Superior performance
Economical
Dependable supply
High purity
Lot-to-lot consistency
Clear, low-color products
STEPANPOL PS-1752 is a diethylene glycol-phtalate anhydride-based polyester polyol.
Non-foam resin and prepolymer use in elastomers, adhesives, and coatings. Flexible polyether and
polyester slabstock urethane for enhanced production of flame laminating, packaging, and reticulated
foams.
Improved polyester hydrolytic stability. Increases polymer modulus, allowing processing at lower
index. Primary hydroxyl advantage. Promotes bonding to various plastics and metals.
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
