Vertellus Polycin M-280 Modified Castor Oil Polyol M 280 Bio-based Heat and Hydrolysis Resistant Polyol

Product introduction
Polycin M-280 is a 100% solids castor oil based derivative designed for use as a polyol in polyurethane coating systems. Polycin M-280, with a high level of reactivity, will impart hardness and strength to polyurethane systems. When used as a reactive diluent, Polycin M-280 will deliver the beneficial properties of castor oil derivatives such as improved flow and leveling.
