  • Applications

    Rustoside, CAS 83144-68-7, is viewed as an organic synthesis intermediate and may be used as a solvent in certain processing steps; it often serves as a stabilizer and/or chelating agent in polymer and coating formulations to improve metal compatibility and formulation durability. It can also function as an additive for plastics, adhesives, and coatings to enhance processability, adhesion, and manufacturing performance. In industrial cleaning applications, Rustoside may act as a solvent component or cleaning aid. It is also considered as a processing aid or surfactant in specialized polymer systems. Its use should comply with local regulations and formulation limits.
