Rosin special for yellow soldering has high purity, heat resistance, oxidation resistance, no pungent odor and other physical properties. Wetting, spreading and rheological characteristics: make the welding point meet the mechanical requirements of mechanical and electrical connection. Under the action of a catalyst, the polymerized rosin resin prepared by co-altering the bond and undergoing a polymerization reaction has a relatively high softening point, has a huge molecular structure, is not o
