  • Applications

    Palustric acid, CAS 1945-53-5, is a resin acid derived from pine rosin. In industry, it is primarily used as a base material for rosin-based tackifying resins that increase adhesion, serving as a tackifier in adhesives and in coatings and inks. It is also used as an intermediate for the synthesis of functionalized esters and other specialty derivatives for polymer formulations. Additionally, palustric acid can participate in polymer stabilization packages, particularly as a component in PVC stabilizers, and serves as a feedstock for rosin-derived derivatives used in various resin and coating formulations.
