colophonium gum rosin

1,Gum rosin use in ink, adhesive, paint, food and rubber industry 2,gum rosin name colophony 3,ISO9001:2008 CERTIFICATE

GENERAL DESCRIPTION & APPLICATIONS

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 resinate 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.

Special Properties of Gum Rosin

Natural organic compound, mainly composed of resins, possesses chemical activity when dissolved in many organic solvents.
