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.

Application
• Formulated 100% solids high performance polyurethane coatings
• Low VOC UV resistant two-component industrial maintenance coatings and thermosetting OEM coatings
• Improved properties: flexibility, adhesion, moisture resistance and chemical resistance of coatings, adhesives, sealants, and elastomer formulations
• Low VOC force drying and baking of topcoats and primers for plastics and primers for metals
• Low viscosity, solvent-free pigment dispersion for polyurethane and polyurethane-melamine baked systems.
• VOC and viscosity reduction in coatings, adhesives and sealants
• Polyurethane intermediates, polymers
