Description

Soybean Oil, Glycerine, Phthalic Anhydrided Polymer CAS NO 68918-58-1 is a specialized polymeric material derived from the reaction of soybean oil, glycerine, and phthalic anhydride. This product is valued for its versatility as a building block in polymer synthesis, offering a balance of properties from its renewable and synthetic components. It is primarily required by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing alkyd resins and plasticizers.

Application

• Primary raw material for the synthesis of modified alkyd resins used in industrial and decorative coatings.
• Production of polymeric plasticizers for PVC and other flexible polymer compounds.
• Key intermediate in formulating adhesives and sealants with enhanced flexibility and adhesion.
• Base component for urethane polyols and other specialty polymers.
• Used in the manufacture of corrosion-resistant primers and metal coatings.
• Potential use in biobased polymer research and development.
