Description
Gum rosin
Grade: X Grade, WW Grade
Purity: 99.9
Other name: Colophony
CAS No. 8050-09-7
Molecular formula: C20H30O2
Molecular weight: 302.44
Appearance: Light yellow transparent solid 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 f
urther use by its double bond reaction. Specifications:
Packing: 225kg/drum, 21.6mt /20"FCL
Storing and Transporting: Gum rosin must be kept away from heat and flame
