Castor oil is the triglyceride of oleic acid. Castor oil is produced in the seeds of castor oil, and its proportion is 35%～57%." Castor oil is obtained by pressing or solvent extraction. There is basically no color or slightly yellowish color. It is clear and thick liquid; slightly gas; light and then slightly pungent. It is soluble in ethanol and can be mixed freely with absolute ethanol, chloroform, ether or acetic acid. It should be common in the field of paints and coatings.

There are many types of castor oil, so let’s take you to know the oxidized castor oil and epoxidized castor oil:

Oxidized castor oil is commonly referred to as blowing oil and blowing oil. It is made by oxidizing castor oil at high temperature. The resulting substance is a more complex mixture with various structures. It is specifically used for toughening of nitrocellulose lacquer. Agent, real paint, spray paint, can be used in polyurethane paint.

Epoxidized castor oil is obtained from castor oil which can be directly reacted with ethylene oxide or propylene oxide to carry out alkoxylation reaction. It can also be dissolved or alcoholyzed and then carried out alkoxylation reaction, and it can also be hydrogenated and then Carry out alkoxylation. The obtained epoxidized castor oil has a performance comparable to that of epoxidized soybean oil, and it is also used in paints and coatings.
