indene resin

Coumarone indene resin is a kind of resin material obtained by treating and refining benzofuran and indene contained in specific distillation section of coal tar, and then catalytic copolymerization. Coumarone indene resin is a commonly used base coating in the field of heavy anti-corrosive coatings. Compared with traditional epoxy and polyurethane polyurea, Coumarone indene resin has strong water resistance, insulation, acid alkali resistance and corrosion resistance. It is mainly used in the shipbuilding heavy anti-corrosion coating industry, high-voltage transmission and transformation insulation material industry, adhesive industry and tire rubber industry.

As Coumarone indene resin mainly adopts horizontal polymerization, its chemical structure is more stable than that of petroleum resin, with high softening point, large molecular weight, small taste and light color. It also has excellent fluidity and compatibility different from petroleum resin, and can improve the physical properties of various rubbers, significantly improve the adhesion between adhesives and electronic materials, and improve the corrosion resistance of paint.
