STEPANPOL PS-20-200A is a prepolymer grade aromatic polyester polyol that promotes adhesion to metal as well as having inherent UV stability thereby finding use in various coatings and adhesives.

This product can be used in formulating urethane coatings, adhesives, sealants and elastomers. It can also be used in flexible polyether and polyester slabstock urethane for enhanced production of flame laminating, packaging and reticulated foams. This product exhibits excellent hydrolysis resistance, very good thermal stability and primary hydroxyl advantage. It may promote adhesion to a variety of metal and plastic substrates. It increases polymer modulus, allowing processing at lower index. STEPANPOL PS-20020A is suitable for uses in prepolymers.
