  • Applications

    1,26-Hexacosanediol (CAS 15541-01-2) is a long-chain diol used mainly as a diol monomer or chain extender in polyester and polyurethane systems to introduce long, flexible soft segments in resins and elastomers. In coatings and inks, it may serve as a reactive diol component to adjust film properties such as flexibility, abrasion resistance, and adhesion. In PU-based adhesives and sealants, it is used to enhance elasticity and bond strength. Due to its long aliphatic chain, it can act as a processing aid or softening additive in plastic and coating formulations to improve compatibility with waxes, oils, and other hydrophobic constituents. Additionally, it may be an intermediate for the synthesis of specialty polymers and functional materials, depending on formulation needs and local regulations.
