Vertellus Polycin D-290 Modified Castor Oil Polyol D 290 Bio-based Heat and Hydrolysis Resistant Polyol

Product introduction
Polycin D-290 is a 100% solids castor oil based derivative used as a polyol or reactive diluent system in polyurethane coatings. Polycin D-290 has a very low viscosity and can be formulated with higher system solids for improved VOC reduction.
Polycin D-290 also imparts derivatives of castor oil beneficial properties such as improved flow and leveling.
