Novolac epoxy resin (F-type epoxy resin) has a wide range of applications, and o-cresol epoxy resin is its representative product.

Phenolic epoxy resin is also called F-type epoxy resin. Its chemical name is novolac polyglycidyl ether and it is a heat-resistant epoxy resin. Phenolic epoxy resin appears as a brown, high-viscosity transparent liquid with a faint ammonia odor. It has the characteristics of solvent resistance, chemical resistance, good thermal stability, and good electrical insulation. It is widely used in aerospace, automobile manufacturing, architectural coatings, electronics, etc. Wide range of applications.

According to different base materials, phenolic epoxy resin can be divided into three types: bisphenol A type novolac epoxy resin, phenol type novolac epoxy resin and o-cresol type novolac epoxy resin. O-cresol epoxy resin (EOCN) is made from epichlorohydrin and o-cresol resin as raw materials. It has the advantages of excellent processing performance, corrosion resistance, acid and alkali resistance, etc., and is used in the fields of large-scale integrated circuits and semiconductor integrated circuit packaging. More. In recent years, benefiting from technological progress, the quality and output of o-cresol epoxy resin in my country have continued to improve, driving the development of the phenolic epoxy resin industry to accelerate.

The main raw material of phenolic epoxy resin is phenolic resin. Its main preparation methods include ion exchange method, solid phase polymerization method and solvent polymerization method. With the improvement of technology maturity and increasingly strong market demand, my country’s phenolic resin output continues to grow, reaching nearly 2 million tons in 2022, setting a record high. Phenolic epoxy resin is a commonly used polymer material. Benefiting from sufficient supply of raw materials, its industry development trend continues to improve.

According to the “2023-2028 China Phenolic Epoxy Resin (F-Type Epoxy Resin) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center >》 shows that phenolic epoxy resin is mainly used in aerospace, automobile manufacturing, architectural coatings, electronics and electrical and other fields. In the field of aerospace, phenolic epoxy resin can be used in aerospace heat-proof coating systems, including aircraft casings, engine nozzles, etc.; in the field of automobile manufacturing, phenolic epoxy resin can be used to produce automobile structural parts, including automobile chassis, automobile Protective covers, etc.; in the field of architectural coatings, phenolic epoxy resin can be used as the base material for anti-corrosion coatings; in the field of electronic and electrical products, it can be used as electronic packaging materials.

Local companies and Sino-foreign joint ventures dominate my country’s phenolic epoxy resin market, including Jiangsu Sanmu Group and Sichuan Dongcai Technology Group. Dongcai Technology is actively promoting the commissioning of a special epoxy resin and intermediate project with an annual output of 60,000 tons. After the completion of the project, its annual production capacity of phenolic epoxy resin will reach 5,000 tons.

Industry analysts said that as a special epoxy resin, phenolic epoxy resin has excellent performance and has broad application prospects in many fields. In the future As market demand gradually releases, its industry prosperity will further improve. my country is a major producer of phenolic resin, and its raw material advantages have laid a good foundation for the development of the phenolic epoxy resin industry. In terms of market competition, my country’s phenolic epoxy resin industry is highly concentrated, and Dongcai Technology is the leading company in my country.
