Blown Castor Oil

Blown castor oil is a viscous liquid with a honey-golden hue, produced through the process of oxidative polymerization. This substance is also referred to as oxidized castor oil or polymerized castor oil. The production involves introducing air or oxygen into castor oil at temperatures ranging from 80 to 130 degrees Celsius. Manufacturers of blown castor oil utilize oxidative polymerization to create products that exhibit enhanced viscosities, improved compatibility with various resins, and superior capabilities for wetting and dispersing pigments. Additionally, this process imparts solvent and abrasion resistance to lacquer systems, making them highly resilient to environmental conditions and industrial emissions. Like other castor oil derivatives, blown castor oil finds a wide range of applications, including its use as a plasticizer for different resins in adhesives, heat-set inks, and sealant systems, as well as serving as a lubricant base that is resistant to oil and solvents for plug valves.
