Packaging

1 L in poly bottle

250 mL in poly bottle

Physical form

Terminal primary dihydroxy-functional oligomer.

Application

Hard and soft surface cleaners, defoamers in coatings and water treatment. Lubricant in metal working, anti-foaming aid and extender for linear and cross-linked polyesters and polyurethanes.

Features and Benefits
