CAS No: ********7
Standard: X WW WG N M K GB/T*************3
Appearance: Yellow transparent solid
Properties: Hard, amber resin. Soluble in acetone and benzene,

Introduction:
Gum rosin also called colophony, is a solid form of resin obtained
from pines and some other plants, mostly conifers, produced by
heating fresh liquid resin to vaporize the volatile liquid terpene
components. It is semi-transparent and varies in color from yellow
to black. At room temperature rosin is brittle, but it melts at
stove-top temperatures. It chiefly consists of different resin
acids, especially abietic acid.
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.
