With the enhancement of environmental awareness and continuous advancements in industrial technology, traditional solvent-based epoxy curing agents are gradually being replaced by more eco-friendly waterborne alternatives. Waterborne one-component epoxy curing agents, characterized by low toxicity, low volatility, and ease of operation, demonstrate significant potential in fields such as architectural coatings, automotive repairs, and electronic encapsulation. This paper provides an in-depth analysis of the chemical composition, performance characteristics, application scope, and future development trends of waterborne one-component epoxy curing agents.

I. Chemical Composition of Waterborne One-Component Epoxy Curing Agents

Waterborne one-component epoxy curing agents primarily consist of epoxy resins as the core component, supplemented with curing accelerators, diluents, and other additives. Epoxy resins offer excellent mechanical properties, chemical resistance, and electrical insulation. The curing agent initiates chemical reactions during the curing process, enabling the epoxy resin to form a stable three-dimensional network structure, thereby achieving adhesion and protective functions. To improve curing efficiency and reduce costs, auxiliary materials such as fillers and pigments may also be incorporated.
