Introduction: Waterborne epoxy curing agents are a critical class of chemical materials used to fabricate high-performance epoxy coatings and composites. They react with epoxy resins to form stable three-dimensional network structures, enabling adhesion, protection, and reinforcement of substrates. With the increasing stringency of environmental regulations and the pursuit of sustainable development, these curing agents have gained widespread attention due to their low volatile organic compound (VOC) emissions. This article explores the fundamental knowledge, classifications, performance characteristics, and application fields of waterborne epoxy curing agents.

I. Basic Knowledge of Waterborne Epoxy Curing Agents

1. Definition: Waterborne epoxy curing agents are epoxy resin curing agents using water as a solvent or dispersion medium. They typically contain reactive functional groups, such as epoxy groups, which cross-link with epoxy groups in the resin to form stable polymer networks.
2. Composition: These curing agents primarily consist of resin matrices, curing agents, accelerators, fillers, and pigments. The resin matrix determines the performance, the curing agent provides reactivity, accelerators speed up the curing process, and fillers/pigments impart specific properties and application characteristics.
3. Function: The main role of waterborne epoxy curing agents is to chemically react with epoxy resins, forming stable cross-linked networks that enhance mechanical strength, chemical resistance, and weatherability of coatings or composites.
