Description

Fatty Acids,C18-Unsatd.,Dimers,Polymers With Ethylenediamine,Glycerol,Isophthalic Acid,Pentaerythritol,Tall Oil And Tall-Oil Fatty Acids CAS NO 72480-46-7 is a complex, high-performance polymeric resin synthesized from a blend of tall oil derivatives and polyfunctional monomers. This product is engineered to deliver exceptional thermal stability, chemical resistance, and robust mechanical properties, making it a critical component in demanding industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite materials.

Application

• High-Performance Industrial Coatings: Used as a binder or resin modifier in alkyd, epoxy, and polyurethane coatings for heavy-duty machinery, marine applications, and protective industrial finishes.
• Adhesives and Sealants: Serves as a key polymeric backbone providing flexibility, adhesion, and durability in construction and automotive sealants and structural adhesives.
• Elastomers and Rubber Compounding: Acts as a processing aid, tackifier, or reinforcing agent in the production of specialty rubber products.
• Composite Materials: Utilized as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems requiring enhanced toughness.
• Printing Inks: Incorporated into resin formulations for specialty printing inks to improve gloss, adhesion, and rub resistance.
• Foundry Core Binders: Employed in binder systems for sand cores and molds in metal casting processes.
