STEPANPOL polyester polyols offer formulators versatility to tailor industrial coatings, radiation curable oligomers and polyurethane dispersions (PUDs). These products may be used as building blocks in 1K coatings or as primary reactants in 2K coatings. These polyols are used to make coatings with very good abrasion resistance, adhesion, chemical resistance, and/or weatherability. These products can be compatibilized with other resin systems such aspartic and acrylic polyols.
Stepan offers a broad range of aliphatic and aromatic polyesters including prepolymer grade products. Prepolymer grades are neutralized to slow their reactivity with isocyanates in prepolymer manufacture.
