  • Applications

    7-Hexadecenedioic acid, (7Z)-, is a long-chain unsaturated dicarboxylic acid used as a monomer or comonomer in the production of polyesters and other polymers, particularly in coatings and composite resin systems. Its double bond at C7 enables conversion to anhydrides or acid chlorides to prepare polyester resins, adhesives binders, and crosslinkable systems for coatings and inks. It also serves as a precursor for ester derivatives that can be used to formulate lubricants or plasticizers for plastics. In specialty polymers and bio-based formulations, it is regarded as a building block for polymer materials derived from renewable resources. Derivatives of the diacid may be used in coating, resin, and adhesive formulations, depending on local regulations and formulation constraints.
