Soft and tough liquid epoxy resin developed successfully

China's epoxy resin industry online According to the news of Wuxi Di Aisheng, a spokesman for Japan's Dainippon Ink Co., Ltd. said on the 3rd September that they have developed and produced epoxy resins with a liquid oligomeric bifunctional molecular structure. This is achieved by introducing a low polarity binding group into the epoxy resin molecular structure.
According to data from Dainippon Ink Co., Ltd., this flexible, tough liquid epoxy resin has five excellent characteristics: First, it has low viscosity, easy operation, and a special relationship between molecular weight and viscosity - the same molecular weight as general-purpose BPA solid resin , Viscosity and general type BPA liquid resin is the same; second, excellent flexibility and toughness, can withstand 180 degrees repeated bending test; Third, the adhesive force is extremely high, 1 to 4 times higher than the general BPA liquid resin; four is curing Shrinkage is very small, only one-tenth to one-tenth; Fifth, less impurities, high purity, its COD content is 80% less than the general BPA liquid resin. This product is expected to be used in electronic technology cutting-edge materials, special coatings, adhesives, carbon fiber composite materials and other applications.
According to an expert from China Epoxy Resin Industry Association, epoxy resin has the advantages of formability, heat resistance, adhesiveness, and electrical insulation, and is widely used in coatings, adhesives, printed circuit boards, and semiconductor sealing materials. , but its disadvantages are hard and brittle. Recently, in the field of electronic technology, technological developments such as flexible wiring boards require the epoxy resin to maintain good flexibility and toughness.
Dainippon Ink Co., Ltd. has a leading position in the international ink industry and has a long history of producing coatings and epoxy resins. Wuxi Di Aisheng Epoxy Co., Ltd., established in 1997 with Bluestar New Materials Wuxi Resin Factory and jointly invested US$17 million, has become an important production base for China's epoxy resin industry.
