The excellent physical, mechanical, and electrical insulation properties of epoxy resin, its adhesive properties with various materials, and the flexibility of its usage process are not possessed by other thermosetting plastics. Therefore, it can be made into coatings, composite materials, casting materials, adhesives, molding materials, and injection molding materials, and has been widely used in various fields of the national economy. The development direction and modification technology of key supporting products for epoxy resin, such as defoamers and curing agents, have also attracted great attention. And now, the editor of Jianyi Chemical will first introduce it to everyoneDefoamerLet's discuss the six major development directions for the future!
1. Due to the limited progress in developing epoxy resins with new structures and excellent performance, curing agents with special functions will become the darling of the market to meet resin modification requirements. Compared with traditional curing agents, functional curing agents typically have excellent properties such as rapid curing, low-temperature curing, toughening, and flame retardancy.
2. Low toxicity and non toxicity. Currently, the industry not only focuses on the toxicity and environmental pollution issues during the production and use of defoamers, but also attaches great importance to the long-term pollution problem of waste epoxy resin products.
3. Defoamers that can adapt to special environments. For example, curing agents that maintain good and stable performance in harsh environments such as humidity, underwater, and outdoors.
4. Solid defoamers with excellent electrical, mechanical, and mechanical properties will be greatly developed.
5. Electron beam and photopolymerization products are receiving increasing attention.
6. Powder coatings, water-based epoxy resin coatings specialized defoamers, and single component adhesive defoamers have broad prospects.
For the six major development directions of defoamers, specific modification technologies that match them have been proposed, such as fatty amine modification, epoxy resin aromatic amine modification (especially m-phenylenediamine and m-phenylenediamine modification), acid modification and liquefaction, dicyandiamide modification and liquefaction, imidazole modification and liquefaction, etc. It is urgent to accelerate the coordinated development of the defoamer industry for epoxy resin. On the premise of complying with environmental and safety regulations and meeting user needs, continuously reducing costs and developing towards serialization, specialization, matching, and refinement are the long-term tasks of defoamer production enterprises
