Product Overview
Dehydrated Castor Oil (DCO) is a chemically modified drying oil produced by removing hydroxyl groups from refined castor oil through a carefully controlled dehydration process. This modification converts castor oil from a non-drying oil into a highly functional drying oil with improved oxidative curing properties, making it suitable for surface coatings and film-forming applications.
At Nova Industries, DCO is manufactured using precise temperature control and reaction monitoring to achieve consistent conjugated double-bond formation. This controlled chemistry ensures reliable drying behavior, uniform film formation, and predictable performance across batches—critical requirements for coatings and resin manufacturers.
Unlike raw castor oil, Dehydrated Castor Oil exhibits enhanced air-drying characteristics, good gloss development, and strong adhesion. It is widely used where natural, bio-based alternatives to petroleum-derived drying oils are preferred without compromising technical performance. Buyers select Nova Industries’ DCO for its process reliability, formulation compatibility, and consistent supply quality.
