Usage: Uses of Gum Rosin: At present, most rosin product is used for the
manufacturing of paper, paint, soap and printing ink. Since rosin is easily
softened and oxidized, in the oil paint industry, the carboxylation reaction of
resin acid is usually employed to produce resonates for further use. While in
the producing of synthetic rubber and printing ink, resin acid is changed into
disproportionate rosin, polymerized rosin, hydrogenated rosin, etc for
