1.Overview
Dehydrated castor oil fatty acid (DCO-FA) is mainly consist of conjugated linoleic acid（CLA）, linoleic acid, and oleic acid; it also contains a small quantity of stearic acid and palmitic acid with almost no linolenic acid.
Because of the highly active C=C-C=C conjugated double bond, the product has following properties:
● High reactivity, wide applied range. The product can be used in resin modification or directly used in resin synthesis.
● Quick-drying property. Due to high content of conjugated linoleic acid（CLA）, the resin made from this product has good quick-drying property.
● Final product made from this acid has good yellowing and weather resistance, because the total degree of unsaturation is not high, and the double-bonds left in the molecule are minor after sulfidation.
● Final product made from this acid has remarkable physical and chemical properties：good hardness, high adhesion and high performance in acid and alkali resistance etc.
