A critical review of dynamic bonds containing curing agents for epoxy

Investigated the mechanical, thermomechanical, thermal, and recycling properties of the epoxy thermosets cured by developed curing agents. Addressed the challenges, opportunities and emerging trends in the field.

In modern manufacturing, epoxy resins, as high-performance thermosetting materials, are widely used in fields such as electronic encapsulation, automotive manufacturing, and construction due to their excellent mechanical properties, electrical insulation, and corrosion resistance. traditional epoxy resin curing processes often involve the evaporation of organic solvents, which not only pollutes the environment but also poses health risks to workers. developing an environmentally friendly, low-emission aqueous epoxy curing agent has become an urgent issue.

An aqueous epoxy curing agent is a novel epoxy curing system using water as a solvent. It can cure rapidly at room temperature and exhibits physical and chemical properties similar to conventional epoxies. Compared to traditional organic solvent-based epoxy curing agents, aqueous epoxy curing agents offer significant advantages:

1. Environmental Friendliness: Aqueous epoxy curing agents are free of volatile organic compounds (VOCs), greatly reducing environmental and human health impacts. During application and use, they emit almost no odor, minimizing irritation and harm to operators.

2. Safety: Due to their low toxicity, aqueous epoxy curing agents reduce the risk of occupational diseases, such as skin allergies and respiratory irritation. Additionally, they exhibit good fire resistance, making them less flammable in case of fire, thereby enhancing safety on construction sites.

3. Cost-Effectiveness: Aqueous epoxy curing agents are relatively inexpensive and can be reused, reducing resource waste. Their fast curing speed shortens project cycles, lowering production costs.

4. Ease of Application: Aqueous epoxy curing agents are easy to mix and apply, requiring no specialized equipment or conditions. This simplicity speeds up construction and provides significant convenience for workers.

5. Adjustability: The curing time and temperature of aqueous epoxy curing agents can be adjusted according to needs to achieve optimal results. This flexibility ensures peak performance across various applications.

6. Versatility: Aqueous epoxy curing agents are compatible with multiple epoxy resin types, including general-purpose, high-temperature-resistant, and flame-retardant varieties, meeting diverse application requirements.

Despite these advantages, aqueous epoxy curing agents face challenges in practical use. For example, their initial curing speed is relatively slow, requiring additives like catalysts to accelerate curing. Additionally, performance may be affected under extreme conditions, such as low temperatures or high humidity.

To address these challenges, researchers are exploring new formulations and technologies. For instance, cross-linking agents or initiators are introduced to improve curing speed, while formulation and process improvements enhance environmental adaptability. Combining aqueous epoxy curing agents with other eco-friendly materials (e.g., bio-based resins) further boosts overall performance.

Looking ahead, advancing technology and growing environmental awareness will expand the role of aqueous epoxy curing agents in industrial applications. Their eco-friendly, safe, and cost-effective nature positions them as key substitutes for traditional solvent-based curing agents. With ongoing innovation and technological progress, their performance will improve, meeting increasingly complex and demanding applications.

aqueous epoxy curing agents, as low-emission, environmentally friendly solutions, hold immense potential. Through continuous technological innovation and practical application, they are poised to play a critical role in future industrial production, contributing to a greener, more sustainable future.
