Description

Fatty Acids, Dehydrated Castor-Oil CAS NO 61789-45-5 is a specialized derivative of castor oil, where the ricinoleic acid component has been dehydrated to yield a mixture of conjugated and non-conjugated fatty acids. This chemical modification is critical for enhancing its reactivity and performance in high-value industrial formulations. It is an essential raw material for manufacturers in the coatings, polymers, and lubricants sectors seeking to improve product durability and functionality.

Application

• Alkyd Resins & Surface Coatings: A key monomer for producing high-performance, fast-drying alkyd resins used in industrial paints, varnishes, and enamels.
• Polymer & Plasticizer Manufacturing: Serves as an intermediate for synthetic polymers and as a building block for specialty plasticizers that enhance flexibility.
• Lubricants & Greases: Used in the formulation of bio-based lubricants and lithium-based greases, offering good thermal stability.
• Adhesives and Sealants: Imparts improved adhesion and water resistance in various adhesive and sealing compound formulations.
• Chemical Intermediate: Acts as a versatile precursor for further chemical synthesis, including sulfonation and ethoxylation.
