Cashew phenolic amine curing agent is a new type of environmentally friendly epoxy curing agent. The industry is still in its early development stage.

Cashew phenaldehyde amine curing agent is a phenolic amine epoxy curing agent based on cardanol modification and using xylene-n-butanol solvent system. Cashew phenolic amine curing agent is a type of epoxy curing agent. Its appearance is a light brown viscous liquid. It has the advantages of low viscosity, fast curing, low cost, non-toxic and environmentally friendly, and a wide range of ratios. It can replace phenol-based rings. Oxygen curing agents are used to cure epoxy resin, and the cured epoxy resin has excellent water resistance, wear resistance, corrosion resistance, flexibility, heat resistance and other characteristics.

Cashew aldehyde amine curing agent is a new type of non-toxic and environmentally friendly epoxy curing agent. It is mainly prepared from cardanol, paraformaldehyde and amine as raw materials through Mannich reaction. Among them, cardanol is a key raw material for the production of cardan aldehyde amine curing agent and refers to an extract of cashew nut shell oil. Cashew nuts have been introduced and cultivated in my country for nearly seventy years, and are now widely planted in Yunnan, Hainan, Guangdong, Guangxi, Fujian, Taiwan and other places. Based on this, my country has sufficient cashew oil that can be used to extract and prepare cardanol. The supply of upstream raw materials is relatively sufficient, and the cashew aldehyde amine curing agent industry has a good foundation for development.

According to the “2023-2028 Cashew Phenolic Amine Curing Agent Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center It is shown that epoxy curing agent refers to a material that can chemically react with epoxy resin to form a network of three-dimensional polymers and envelop composite materials in the network. It is often used in resins, coatings, glass, etc. Fiber reinforced plastics synthesis field. As a new type of epoxy curing agent, cashew phenolic amine curing agent has all the advantages of phenolic amine curing agent and can be widely used in manufacturing scenarios such as coatings, adhesives, friction materials, surfactants, etc., and can realize the bonding between metals and non-metals. The terminal application fields include ships, construction, automobiles, petrochemicals, machinery and equipment, rail transit, etc.

Cashew phenolic amine curing agent has a wide range of applications and has good market development prospects. At present, domestic enterprises such as Taian Hanwei Group, Shanghai Meidong Biomaterials, Changshu Nexu Biomaterials Technology, Zhejiang Wansheng Co., Ltd., Anhui Meidong Biomaterials, Jiangsu Sanmu Chemical, Shanghai Huayi Fine Chemicals, etc. have entered the cashew phenolic amine curing agent industry. market, but due to technical limitations, the number of companies is still relatively small.

Industry analysts said that cashew phenolic amine curing agent is a new type of environmentally friendly and non-toxic epoxy curing agent agent, which can replace phenol-based epoxy curing agents for epoxy resin curing scenarios. It is an important raw material for preparing ship coatings and industrial anti-corrosion protective coatings. The terminal fields involve machinery, ships, industry and other fields, and the market demand is huge. At present, there are only a small number of enterprises in the field of R&D and production of cashew phenolic amine curing agents in my country. The industry is still in its early stages of development, and there is broad room for future development.
