1、Recycling of Epoxy Curing Agents in Liyang
As a specialized epoxy curing agent recycling manufacturer based in Huzhou, we not only focus on the efficient application of epoxy curing agents but also prioritize maximizing their recovery and reuse, thereby contributing to environmental protection.
2、Recent progress in degradation and recycling of epoxy resin
Amine curing agent is the most common type of epoxy resin curing agents and approximately 71% of all epoxy resins are cured by amine curing agents. Therefore, it is crucial to study the degradation of amine-cured epoxy resins.
3、Facile recycling of anhydride
Herein, we develop a mild, efficient and energy-saving process for degrading anhydride-cured epoxy resins with the aid of hydrazine hydrate. In this system, hydrazine hydrate is chosen as a multifunctional reagent to play the role of a solvent and a reactant during the degradation process.
4、One‐Component Degradable High‐Thermal‐Conductivity Liquid Crystal Epoxy
High thermal conductivity liquid crystal epoxy resins (LCERs) and their composites are essential for efficient thermal management in electronic devices. The production of LCERs currently depends on combining epoxy monomers and hardeners or catalysts. However, these curing agents or catalysts destroy the liquid crystal phase in the crosslinked network, thereby limiting the thermal conductivity ...

Pinggu's Epoxy Curing Agent Recycling Initiative
Committed to the recycling and utilization of epoxy curing agents, the company achieves efficient recovery and resource-oriented use of epoxy curing agents through scientific management and advanced technological methods.
Bona fide upcycling strategy of anhydride cured epoxy and reutilization
Herein, we demonstrated an efficient degradation of anhydride cured epoxy resin by aminolysis in aminoethanol without using any catalysts. The epoxy resin was fully decomposed at 160 °C in 4 h, resulting in two distinct high purity monomers (HHPA-OH and BPA-OH).
In the rapid development of modern society, environmental protection and resource recycling have become increasingly critical. As an essential chemical material, the proper use and responsible recycling of epoxy curing agents significantly impact the environment. This article explores the current status of epoxy curing agent recycling in the Lincang region, the challenges faced, and future development trends.
Epoxy curing agents are indispensable to modern industrial development, widely used in coatings, adhesives, sealants, and other products. These applications play vital roles in industries such as construction, automotive manufacturing, and electronics, enhancing product performance and longevity. improper handling of epoxy curing agents not only poses environmental risks but also complicates disposal due to their complex composition.
As a key city in Western China, Lincang has seen rising usage of epoxy curing agents amid economic growth. This has intensified the challenge of managing waste epoxy curing agents. Traditional disposal methods like landfilling and incineration offer limited solutions. Landfilling consumes valuable land and risks groundwater contamination through leachate, while incineration releases toxic gases, endangering both the environment and human health. Thus, Lincang urgently needs more eco-friendly and efficient recycling approaches.
In recent years, stricter national environmental policies and heightened public awareness have made epoxy curing agent recycling a priority. Lincang has made progress in this area. Governments have invested in advanced recycling facilities, and businesses have explored innovative technologies, such as chemical decomposition to separate organic components, followed by harmless treatment and resource recycling.
Despite achievements, several challenges remain. First, technological barriers limit the number of enterprises capable of recycling. Second, low market demand persists, as many companies discard used epoxy curing agents instead of recycling them. Third, regulatory frameworks are incomplete, lacking incentives to drive recycling efforts.
To address these issues, Lincang must take multiple steps:
- Strengthen technology research: Improve the reliability and maturity of recycling techniques.
- Advance laws and policies: Clarify corporate responsibilities and encourage participation in recycling.
- Raise public awareness: Promote environmental consciousness through education and outreach.
- Establish market mechanisms: Offer government subsidies, tax breaks, and other incentives to attract investment in recycling initiatives.
Looking ahead, recycling epoxy curing agents will become a key industry trend as environmental principles and technologies advance. Lincang is poised to seize new opportunities through innovation, policy refinement, and community engagement. With concerted efforts, epoxy curing agent recycling in Lincang can significantly contribute to environmental protection and sustainable development.
