Uses
Dehydrated castor oil fatty acid based alkyd resins and polyamides make up superior constituent in numerous paint and printing inks formulations.
Styrenated epoxy esters of these fatty acids are used in prime quality automotive paints.
Dehydrated Castor Oil Fatty Acid (DCOFA) is also used in the manufacture of high solid alkyds, acrylic and epoxy ester resins, which are useful for interior and exterior can coatings, appliance finishes, automotive topcoats, primers, coil coatings, tube coatings, marine finishes, overprint varnishes and high-speed printing inks.
Furthermore Dehydrated Castor Oil Fatty Acid (DCOFA) can be used as chemical intermediate because of their conjugate dienes structure.

It is mainly used in production of high solid alkyds, acrylic and epoxy ester resins (useful for automotive topcoats, overprint varnishes, marine finishes, coil coatings, interior and exterior can coatings, tube coatings, primers, and high-speed printing inks)

Dehydrated Castor Oil Fatty Acid commonly known as Dehydrated Castor Oil Fatty Acid (DCOFA) is a high diene Fatty Acid based on Castor Oil.
Dehydration of Castor Oil is carried out at about 2500C in the presence of catalysts and under an inert atmosphere or vacuum.
Dehydrated Castor Oil Fatty Acid (DCOFA) is liquid at room temperature, having a water-white to pale yellow color.

Dehydrated castor oil fatty acid (DCOFA) General Dehydrated Castor oil fatty acid commonly known as Dehydrated Castor Oil Fatty Acid (DCOFA) is a high diene fatty acid based on Castor oil.

Dehydration of Castor Oil is carried out at about 250 C in the presence of catalysts (e.g., Concentrated Sulphuric Acid, Activated Earth) and under an inert atmosphere or vacuum.
Under this condition of dehydration, the Hydroxyl Group and adjacent Hydrogen Atom from the C-11 or C-13 position of the Ricinoleic Acid portion of the molecule is removed as water.
This yields a mixture of two acids, each containing two double bonds but in one case, they are conjugated.

Applications
Dehydrated castor oil fatty acid based alkyd resins and polyamides make up superior constituent in numerous paint and printing inks formulations.
Styrenated epoxy esters of these fatty acids are used in prime quality automotive paints.
Dehydrated Castor Oil Fatty Acid (DCOFA) is also used in the manufacture of high solid alkyds, acrylic and epoxy ester resins, which are useful for interior and exterior can coatings, appliance finishes, automotive topcoats, primers, coil coatings, tube coatings, marine finishes, overprint varnishes and high-speed printing inks.

Conjugated poly unsaturated fatty acids are based on our standard PUFA products where the product is modified by an additional treatment (conjugation).
Conjugated PUFA's are widely used in the production of alkyd resin binder systems where the higher reactivity is mainly used to modify the drying properties of the coating resin.
Main applications are high quality alkyd resins, epoxy resins and water based alkyd resins.
