DYMEREX modified rosin is a pale, acidic, thermoplastic, high softening point resin. It is composed predominately of dimeric acids derived from rosin with lesser amounts of monomeric resin acids and neutral materials of rosin origin. DYMEREX modified resin has high resistance to oxidation and does not crystallize from solutions or from solid compositions. It is compatible with many natural and synthetic film formers and rubbers. Being an acidic resin, it reacts readily with polyalcohols or hydrated lime to yield high melting derivatives.
High softening point; noncrystalline; resistant to oxidation; excellent solvent release properties.
Compatible in useful proportions with natural resins, rubber, and waxes; drying and nondrying alkyds; ethylcellulose; and various synthetic elastomers and plastic polymers and copolymers.
