Gum Rosin is processed from pine gum through a variety of ways and its main ingredients are resin acids. Gum Rosin is widely used in papermaking, ink, paint, coating, adhesive and other industries and can also be used to produce lots of other modified products like disproportionated rosin, polymerized rosin, hydrogenated rosin etc, which obtain special properties by changing the molecular structure, thus greatly improving the quality of the downstream industry products.
