1. It has great flexibility and diversity in formula design.
According to different use performance and process performance requirements, we can design a good targeted formula. This is a major feature and advantage in epoxy resin applications. However, each good formula has a certain scope of application (conditions), and it is not suitable for use under any process conditions and any use conditions. In other words, there is no "" good formula. Different best formulas must be designed according to different conditions.
Due to the different curing principles of epoxy resin curing systems with different formulations, the curing process of epoxy resin, that is, the curing process conditions, has a great influence on the structure and performance of epoxy cured products. The performance of the product obtained by the same formula under different curing process conditions will be very different. Therefore, making the right material formula design and process design correctly is the key to epoxy resin application technology, and also the technical secret.
must deeply understand and master the structure and performance of epoxy resin and its curing agent, modifier, etc., the reaction mechanism between them and the impact on the structure and performance of epoxy cured products. Only in this way can the material formulation design and process design be handy, use freely, obtain a good plan, and produce and develop epoxy materials and products with good performance and low cost.
2. Different epoxy resin curing systems can be cured at low temperature, room temperature, medium temperature or high temperature, and can be cured in a wet table.
The surface is cured even in water, and it can be cured quickly or slowly, so it is highly adaptable to the requirements of construction and manufacturing processes. Epoxy resin can be molded by low pressure or contact pressure molding, so it can reduce the requirements for molding equipment and molds, reduce investment and reduce costs.
3. Among the three general-purpose thermosetting resins, the price of epoxy resin is relatively high, thus being affected to a certain extent in application. However, because of its excellent performance, it is mainly used in applications requiring high performance, especially in areas requiring high comprehensive performance
