1. **Resin Industry**: It is widely used in the production of high - performance epoxy resins. By reacting with epoxy resins, it can improve the heat resistance, mechanical strength, and chemical resistance of the final resin products. These resins are commonly used in the manufacture of printed circuit boards, electrical insulators, and composite materials for aerospace and automotive applications.
2. **Coating Industry**: As a curing agent, 1,2,4,5 - cyclohexanetetracarboxylic dianhydride can be incorporated into coatings. It helps the coatings form a hard and durable film, enhancing the scratch resistance and weatherability of the coated surfaces. This makes it suitable for applications in architectural coatings, industrial coatings, and automotive paints.
3. **Plastic Modification**: It can be used to modify the properties of certain plastics. For example, by reacting with polyesters or polyamides, it can improve their thermal stability, dimensional stability, and mechanical properties. This is beneficial for the production of engineering plastics used in high - temperature and high - stress environments.
When using 1,2,4,5 - cyclohexanetetracarboxylic dianhydride, it is important to follow strict safety and operating procedures. First, ensure that the working environment is well - ventilated to prevent the inhalation of dust. Wear appropriate personal protective equipment, including gloves, goggles, and a dust mask.
In the resin production process, the appropriate amount of 1,2,4,5 - cyclohexanetetracarboxylic dianhydride should be added according to the formulation requirements. Usually, it is mixed with epoxy resins under controlled temperature and stirring conditions. The reaction temperature and time need to be carefully monitored to ensure complete reaction.
In the coating industry, it is added to the coating system in a specific proportion during the formulation process. The mixture should be thoroughly stirred to ensure uniform dispersion. After application, the coating needs to be cured at the appropriate temperature and humidity conditions.
**Case 1: Aerospace Composite Material**
A well - known aerospace company was looking for a high - performance epoxy resin system for manufacturing composite parts. They used our 1,2,4,5 - cyclohexanetetracarboxylic dianhydride as a curing agent in the epoxy resin formulation. After testing, the composite material showed excellent heat resistance, with a high glass transition temperature, and good mechanical strength. It could withstand the harsh environmental conditions during flight, such as high - speed airflow and temperature variations. This significantly improved the performance and reliability of the aerospace components.
**Case 2: Industrial Coating**
An industrial equipment manufacturer needed a coating that could protect their machinery from corrosion and abrasion. By using our product as a curing agent in their coating formulation, they developed a coating with outstanding scratch resistance and chemical resistance. The coated machinery could operate in harsh industrial environments, such as chemical plants and mining sites, for a longer time without significant damage, reducing maintenance costs and improving productivity.
