New Epoxy TEG-99 Advent

Recently, the Chinese Academy of Sciences Guangzhou Chemical Research Institute of turpentine as raw materials, the hydration, catalytic ring-opening, alkaline closed-loop three-cell reaction and post-treatment, synthesis of a new type of epoxy resin TEG-99. Its synthesis technology and product features have three aspects. Mainly: the synthesis process is simple, the main physical and chemical indicators of the product are similar to that of bisphenol A epoxy resin; three types of curing agents commonly used in bisphenol A epoxy resins can be cured, and the cured product has excellent performance; under the same conditions The performance of the technical product and E-44 epoxy resin cured product is equivalent; broadening the scope of application of turpentine oil provides a new way for comprehensive utilization of turpentine oil.

The product can be cured with common amines, polyamides and anhydride curing agents, and the cured product has excellent performance. Under the same curing conditions, the cured product of the TEG-99 epoxy resin and the E-44 epoxy resin cured product have the same performance. China is rich in turpentine oil resources, and its price is low. The main method of deep processing is synthetic spices. Most of the others are used as solvents or exported as primary products. The deep processing rate is not high. Therefore, the synthesis and application of TEG-99 epoxy resin not only broaden the application range of turpentine oil, increase the added value of turpentine oil, but also enriches the types of epoxy resin, and is beneficial to the development of new and new uses of polymer materials.
