Product performance:
1. The main ingredient is a mixture of more than 50% maleopimaric acid grinded adduct, about 35% unreacted resin acid and 10% neutral substance;
2. Dissolved in acetone, ethyl hexanoate and dichloroethane: insoluble in ethanol and solvent gasoline;
3. It has good stability, light resistance and oxidation resistance: its reaction activity is greatly improved.
