Special indene-coumaron resin is a resin material obtained by treating, refining and then catalytically copolymerizing indene and benzofuran contained in specific fractions of coal tar. Since the special indene-coumaron resin mainly adopts transverse polymerization, its chemical structure is more stable than petroleum resin, and it has the characteristics of high softening point, large molecular weight, small taste and light color. It also has excellent fluidity and compatibility different from petroleum resin, and has strong water resistance, insulation, acid and alkali resistance and corrosion resistance, and can improve the physical properties of various rubbers and significantly improve adhesiveness. It can improve the adhesion between agents and electronic materials and improve the corrosion resistance of paints. It is mainly used in the adhesive industry, tire rubber, Marine heavy anti-corrosion coatings, high-voltage power transmission and transformation insulation materials industry, etc.
1.Good tackifying effect , widely used in special adhesive industry.
2. Good compatibility with rubber, used tackifier and filler in rubber industry
3. Good acid and alkali resistance and corrosion resistance , used in heavy-duty anti-corrosion coating industry.
