Properties and uses:
Polymerized rosin is produced by gum rosin through the new technology of "sulfuric acid - zinc chloride", with the features of high dimer content, light color, high softening point, non-crystallization character, high acid value, low content of soluble matter in hot water, good solubility is oil, little discoloration in lead acetate, etc. It is mainly used in printing ink, lacquer, rubber, adhesive, dampproof cloth, paper making and emulsifier, etc.
Packing: Pack in galvanized iron drums (net weight: 255 kg/drum) or according to client's requirements.
Technical indexes: ZBB72008-89; subject to the newest standard if there is alteration; please confirm the newest standard when concluding a contract.
