The development of curing agents in six directions
The recent epoxy resin industry development forum highlighted the future direction and modification techniques of curing agents, which are essential for the growth of the epoxy resin sector. The event emphasized the need for coordinated development within the industry and addressed the issue of advanced production capacity coupled with insufficient market demand. Delegates focused on how to bridge this gap and enhance the overall performance of domestic epoxy resin applications.
Experts in the field outlined six key development directions for curing agents. First, functional curing agents are becoming increasingly important as they offer enhanced properties such as fast curing, low-temperature curing, improved toughness, and flame resistance. These features make them ideal for modern resin modification needs.
Second, there is a growing demand for low-toxicity and non-toxic curing agents. Industry stakeholders are now more concerned not only with the immediate environmental impact but also with the long-term effects of waste epoxy resins on the environment.
Third, curing agents that can perform well in harsh environments—such as humid, underwater, or outdoor conditions—are gaining attention. Their ability to maintain stability and performance under these circumstances makes them highly valuable.
Fourth, curing agents with superior electrical, mechanical, and physical properties are expected to see significant development in the coming years.
Fifth, electron beam and photo-curable products have attracted increasing interest due to their efficiency and versatility in various industrial applications.
Lastly, powder coatings, waterborne epoxy coatings, and single-component adhesives are showing promising potential. Curing agents tailored for these applications are expected to play a major role in the future.
To support these development directions, several modification technologies have been proposed, including fatty amine modification, aromatic amine modification (especially using m-phenylene diamine and m-xylylene diamine), acid modification and liquefaction, dicyandiamide modification, and imidazole-based modifications. These techniques aim to improve the performance and applicability of curing agents.
As the epoxy resin industry moves toward faster and more coordinated development, it is crucial to meet environmental and safety standards while also addressing user needs and reducing costs. The ongoing efforts to achieve serialization, specialization, and refinement in curing agent production remain key challenges for manufacturers.
Experts recommend that epoxy resin and curing agent producers should form strategic partnerships to drive mutual growth. This collaboration is seen as an effective path for the entire industry to thrive and develop sustainably.
Ceramic plates made of zirconia or alumina have excellent weatherability, and they have no effect on the surface and substrate, whether it is sunlight, rain (even acid rain) or moisture. UV resistance and color stability are fully up to international gray level 4-5.Similarly, large or rapid temperature changes will not affect the properties and appearance of the material. The reasonable combination of bending strength and elasticity makes the ceramic plate have high impact strength. The dense material surface makes it difficult for dust to adhere, making it easier to clean.
