Description

Castor Oil, Dehydrated, Polymd. is a chemically modified derivative of castor oil, specifically polymerized and dehydrated to enhance its performance characteristics. This specialized grade is valued for its excellent film-forming properties, high viscosity, and chemical resistance, making it a superior alternative to standard drying oils. It is primarily used in the formulation of high-performance industrial coatings, inks, adhesives, and sealants where durability and specific rheological properties are required.

Application

• As a primary resin or modifier in alkyd resin formulations for industrial and protective coatings.
• As a high-viscosity, reactive polyol component in the production of polyurethane coatings, adhesives, and sealants.
• In the formulation of specialty printing inks, contributing to gloss, adhesion, and drying properties.
• As a binder and film-forming agent in wood finishes and varnishes.
• As a plasticizer and stabilizer in specific polymer and elastomer systems.
• In the manufacture of corrosion-resistant primers and metal coatings.
