Stepanpol PN-110 Ortho phthalate-neopentyl glycol polyester polyol Stepan PU - Polyols >> Polyester ADHESIVE >> Hot-melt ADHESIVE >> Solvent based ADHESIVE >> Radiation Curing (UV/EB) ADHESIVE >> Water-based SEALANT >> Foam 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 adhesive formulations. These polyols are low Tg and amorphous (or non crystalline) in their morphology. They tend to lower melt viscosity and flow point. They strongly increase elasticity. Because of their good wetting capacities, these products can provide enhancements of adhesion to a variety of substrates. Some potential adhesive applications include: synthesis of urethane prepolymers for reactive hot melt adhesives synthesis of water borne polyurethane dispersions formulation of liquid urethane adhesives synthesis of radiation curable oligomers polyol cross linker in radiation curable, cationic cure formulations reactive diluents to increase the solids content of solvent based adhesives epoxy flexibilizers for adhesive and molding/potting applications STEPANPOLPN-110 is a neopentyl glycol-phthalate anhydride-based polyester polyol. STEPANPOL PN-110 can be used in urethane adhesives and coating applications. It is useful in formulating urethane prepolymers and elastomers. Excellent hydrolysis resistance, very good thermal stability, and primary hydroxyl advantage. Steep viscosity/temperature curve. Good hardness/flexibility balance.
