Epoxy resin industry curing agent

Since the 1990 s, the world development trend of epoxy resin curing agent appeared many new characteristics, China epoxy resin industry association experts summarized as the following aspects.

Epoxy resin industry curing agent, look from the product type varieties emerge in endlessly, amine is still in the lead, followed by acid research department, including P, Si, B, F, Mg and other elements of "half inorganic polymer" curing agent with its unique performance attention, modification of mercaptan and modification of phenolic curing agent have different levels of development, has a thiol group at the end of the new block copolymer mass market.

From the trend of the development direction in six:

Is a functional curing agent become the hot spot of research and development, has solidified, toughening, flame retardant, and promote the function such as the versatility of curing agents become people the pursuit of the ideal products, due to the development of new structure and excellent performance of epoxy resin little progress, to meet the requirements for resin modified functional additives become the goal of a dose of pluripotent products more and more, at the same time, fast curing, low temperature curing and minimum water absorption of curing agent has been developing rapidly, the special function of curing agent, such as flexible curing agent also has a great development;

Second, low toxicity, no poison, people not only pay attention to in the process of curing agent in the production and use toxicity and environmental pollution, and attaches great importance to the environmental pollution of the waste epoxy resin, developed countries primary polyene more glue, aromatic amines have been replaced by the non-toxic or low toxic modified amine;

3 it is to adapt to the special environment (damp, underwater, outdoor, etc.) used in curing agent popular;

Four is to meet the requirements for high performance processing for epoxy resin, excellent mechanical properties, excellent electrical performance, mechanical properties of curing agent will get great development;

Fifth, electron beam and light type of curing agent is getting more and more cause the attention of the people;

Six is powder coating for curing agent, waterborne epoxy resin coatings for water soluble than fixing agent and dedicated one-component adhesive curing agent dosage is very big, broad prospects.

Look from the manufacturing technology embodies the four trends:

A modification is blue at Manila, is increasingly widely used, such as fatty amine modified, 4, - fragrant amine modified (especially m-phenylene diamine, between benzene dimethylamine modification), acid modified and liquid, the dicyandiamide modified and liquid modification, imidazole and the liquid, and the modification of low molecular weight poly cool amine;




Chinese name: Diethyl toluene diamine(DETDA)

Diethyltoluenediamine Raw material ：

TDA industrial, Sichuan production

Ethylene (Et) polymer grade, Shanghai production

TEA industrial imports

A reagent grade additives


Second, the distribution of efficiency and unitized burgeoning technology, the toxicity, environmental regulations and factors such as cost, efficiency, more difficulties in the development of a new structure of curing agent, through the distribution of load and improve the efficiency of the increasingly become an effective way to develop new curing agent;

Three is a solid solidification liu liquid technology is very promising, such as temperature and solid acid anhydride, dicyandiamide by modified to make it to a liquid at room temperature, not only can improve the operation and use of performance, and can save energy;
Four is the production and packaging of fine operation. Users and the market demand is pulling speed around curing agent of the development of the big driving force. China epoxy resin industry association experts say, it is mainly manifested in the user puts forward higher and newer requirements on curing agent, such as: use absolutely safe and reliable, to adapt to global environmental, health and safety trend; Application effect is significantly improved, excellent quality is outstanding;

Convenient to use and stored; Price is appropriate, cost - effectiveness of balance, is willing to buy and use; High purification and transparent.

Add to the demand of the market development trend, the seriation, specialty, form a complete set to change, the fine development;
In accord with environmental protection laws and regulations and meet user demand under the premise of continuously reduce cost and achieve higher profits; Curing agent factory and curing agent users to form a partnership, achieve a win-win situation.

The epoxy resin curing agent from the perspective of market competition and development strategy, the manufacturer is generally attach importance to the cultivation of curing agent research and development of high-quality comprehensive talents, technical transformation and new product development active at the same time, strengthen the scientific research a production, application research and development management system, strengthen the protection of intellectual property rights, and the development of epoxy resin, promote each other.

For the research and development than epoxy resin curing agent, compared with the varieties of epoxy resin, curing agent varieties more, and confidentiality is very strong. Each working on a new curing agent can solve a problem, is equivalent to the development of a new epoxy resin or opens up a new USES epoxy resin.
