Blown Castor Oil

Definition

Blown Castor Oil or Oxidized Castor Oil is produced by bubbling air or oxygen through castor oil at elevated temperatures, to obtain oils of varying viscosity.

Applications

Blown Castor Oils are excellent permanent plasticizers. Due to the polarity introduced by the addition of oxygen to the castor oil, blown castor oils are efficient wetters. They are excellent vehicles for pigment dispersion.

Blown Castor Oils are noted for their solvent resistance and find use in caulks and plug valve lubricants. In polyurethane prepolymer systems the blown Castor Oils impart weatherability, film build, high gloss, and gloss retention
