Product Overview
Dehydrated Castor Oil Fatty Acid (DCOFA) is a chemically modified fatty acid obtained by dehydrating castor oil followed by controlled splitting and purification. This process transforms the naturally hydroxylated structure of castor oil into a conjugated unsaturated fatty acid system, giving the product strong drying and film-forming characteristics.
At Nova Industries, DCO Fatty Acid is manufactured with precise control over dehydration severity, reaction time, and purification, ensuring consistent acid value, color, and drying behavior. This level of control is critical for downstream users such as alkyd resin and coating manufacturers, where fatty acid variability can directly affect curing speed, gloss, and film integrity.
Compared to standard fatty acids, Dehydrated Castor Oil Fatty Acid offers enhanced oxidative curing, good solubility in resin systems, and reliable compatibility with solvents and modifiers. Buyers select this product when they require a bio-based drying fatty acid that delivers repeatable performance in demanding industrial formulations.
