Finsyl 7230 Maleated gum rosin Finjetchemical Industries Maleic Resins Inks INKS Pigment concentrates Other industry >> Paper coatings Finsyl7230 is a maleated gum rosin with increased reactivity recommended for use as an intermediate in the production of other rosin derivatives. Reaction of maleic anhydride with rosin forms a maleo-pimaric acid, which has three carboxyl groups instead of one. Softening point, and oxidation stabilityof the rosin is raised. Offers low softening point,High acid number, can be easily disolved in aqueous NaOH. Used in pigment resination, fortified paper-sizing agent ,film-former and plasticizer in “E” type lacquers and varnishes. Maleated gum rosin.
