Refined rosin modified resin is the transparent solid, which is made from refined gum rosin through eaterification with glycerol or pentaerythritol, which with the advantage of exhibit almost water white,aging resistance and excellent compatibility with the macromolecule material.
1. Light color, low odor, good hot-stability and excellent anti-oxidation. It can improve the bonding strength for solvent-based adhesive, press-sensitive adhesive and hot-melt adhesive.
2. Good solubility: Wide soluble in aromatic and aliphatic hydrocarbon solvents, eates,ketones and chlorinated solvents,etc.
3. God compatibility: Free compatible with EVA,SIS,SBS,NR,CR,SBR, and other polymers at free percentage.
