Product Introduction
Polycin D-290 is a 100% solid castor oil-based derivative used as a polyol or reactive diluent system in polyurethane coatings. Polycin D-290 has an extremely low viscosity, and can be used to prepare higher system solids to increase VOC reduction.
Polycin D-290 also imparts beneficial properties derivatives of castor oil, such as improved flow and leveling.
