Gum rosin

Product Description

Product Name : Gum rosin Specifications: Grade: X Grade, WW Grade Purity: *9.9% Other name: Colophony CAS No. ********7 Molecular formula: C*0H*0O2 Molecular weight: **2.*4 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 further use by its double bond ***** Packing: **5kg/drum, *1.6mt /*0"FCL Storing and Transporting: Gum rosin must be kept away from heat and flame Parameter Grade Standard WW APPEARANCE Transparent COLOR Pale Yellow SOFTENING POINT(R&B)CD *6.0 ACID NUMBER(mg KOH / g)≥ **6.0 UNSAPONIFIABLE MATTER % ≤ 5.0 ETHABOL INSOLUBLES % ≤ 0.**0 ASH CONTENT % ≤ 0.**0
