Applications
Commercial and industrial applications for DCO Fatty Acid supplied from our Deodar plant.
High-Solids Alkyd Enamels
Conjugated diene structure enables the synthesis of high-solids, low-VOC architectural alkyd resins with outstanding gloss and color retention.
Learn more →Stoving & Baking Enamels
Used where low yellowing in baking finishes is required, imparting chemical resistance, flexibility, and light-stable characteristics to industrial baking finishes.
Learn more →Epoxy Ester Resins
Reacts with bisphenol-A epoxy resins to yield rapid-curing, corrosion-resistant primers and maintenance coatings.

Frequently Asked Questions
Why is DCO fatty acid used where low yellowing in baking finishes is required?
Conjugated 9,11-octadecadienoic acid promotes rapid oxidative cross-linking while resisting thermal discoloration during high-temperature baking finishes.
What conjugated diene fraction and acid value are specified for DCO fatty acid?
Target parameters include an acid value of 195 to 205 mg KOH/g and distilled fatty acid profile as per specification for high-reactivity color-stable baking enamels.
In what coating systems is DCO fatty acid formulated?
High-solids industrial stoving enamels, light-stable architectural finishes, and chemical-resistant epoxy ester primers.
