Refined Rosin Modified Resin (2016)

This refined rosin modified resin is a transparent solid, approximate to water white. It is formulated by the refined gum rosin esterified through glycerol or pentaerythritol.

1. This substance has a plurality of highlights, such as aging resistance, slight odor, excellent thermal stability, oxidation resistance and optimized bonding strength for solvent-based adhesive, pressure sensitive adhesive, hot melt adhesive, etc.
2. Our refined rosin modified resin is easy to be dissolved in wide range of solvents, such as aromatic and aliphatic hydrocarbon solvents, eaters, ketones and chlorinated solvents, etc.
3. It offers high compatibility with the macromolecule materials at arbitrary percentage, like EVA, SIS, SBS, NR, CR, SBR, etc.
