Stepanpol PD-110 LV Ortho phthalate-diethylene based 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 STEPANPOL® polyester polyols can be used in sealant formulations. These polyols are low Tg and amorphous (or non crystalline) in their morphology. They tend to lower melt viscosity and flow point. Because of their good wetting capacities, these products can provide enhancements of adhesion to a variety of substrates. Some potential sealant applications include synthesis of urethane prepolymers polyol curative for two component urethane sealants formulation of polyurethane foaming sealants and adhesives formulation of liquid urethane adhesives as a modifier to promote adhesion and to reduce raw material cost reactive diluents to increase the solids content of solvent based sealants STEPANPOL PD-110 LV Chemical Description ORTHO PHTHALATE-DIETHYLENE BASED POLYESTER POLYOL product exhibits excellent hydrolysis resistance, good thermal stability and low polyol viscosity. It may promote adhesion to a variety of metal and plastic substrates. It exhibits a good hardness/flexibility balance, clarity and low color. It can improve selected physical properties such as tensile strength, modulus and tear strength as well as compatibility with some polyethers and some isocyanates.
