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 further use by its double bond
reaction.
Storing
and Transporting: Gum rosin must be kept away from heat and
flame.
