1. Basic Concept and Classification of Fast-Curing Epoxy Curing Agents
Fast-curing epoxy curing agents are additives that rapidly initiate chemical reactions at room temperature or low temperatures, transforming liquid epoxy resins into hard, solid materials. They typically exist in liquid or powder forms and can be mixed with other resins. Based on reaction conditions, these agents are classified into two main types: thermosetting and photocurable. Thermosetting agents accelerate reactions through heating, while photocurable agents rely on specific light wavelengths to trigger curing.
