I don't know if you are familiar with methyltetrahydrophthalic anhydride. In fact, some people are not too familiar with it. In fact, what many people have always wondered is what are the functions of methyltetrahydrophthalic anhydride and the precautions for use. Next, the following editor will help you summarize the relevant knowledge.

Methyltetrahydrophthalic anhydride is used as epoxy resin curing agent, solvent-free paint, laminates, adhesives, etc. It has excellent properties such as long-term coexistence at room temperature, low freezing point, and low toxicity. It is widely used in the electronic and electrical industry, such as: dry type transformers, insulators, insulating basins, insulating sleeves, insulating paint, high voltage switches, transformers, line output transformers, electric power and household capacitors, petroleum pipelines. Methylhexahydrophthalic anhydride is especially suitable for outdoor use places, such as outdoor transformers, light-emitting diodes, and oils, in addition to the above-mentioned fields.

In recent years, due to the rapid development of automatic molding technology for epoxy insulating products, new insulating materials using this type of products as raw materials have replaced traditional materials such as bakelite, SMC, porcelain, etc., and are widely used as epoxy insulating materials. And the market demand is increasing.

With the rapid development of China's four pillar industries of the electronic and electrical industry and the transfer of the world's manufacturing centers for such products to China, the application of epoxy resins in this field is bound to increase significantly, and it is matched with the acid anhydride curing agent used in this field. It will also grow simultaneously. By 2015, the acid anhydride curing agent used in the electronic and electrical industry in my country will reach 200,000 tons, of which, it can reach 40,000 tons only for dry-type transformers. The main varieties are methyltetrahydrophthalic anhydride and methylhexahydrophthalic anhydride. Especially with the vigorous development of the wind power industry, the corresponding demand for composite materials such as resins and coatings for wind turbine components is increasing, which has found a new growth point for the market application of acid anhydride curing agents.

The above summary of the knowledge about methyltetrahydrophthalic anhydride, I wonder how much knowledge you have learned after reading it.
