Curing agent

Curing agent, also known as hardener, curing agent or setting agent, is a class of substances or mixtures that enhance or control curing reactions. Resin curing is a process of irreversible change of thermosetting resin through condensation, closed-loop, addition or catalysis and other chemical reactions, curing is completed by adding curing (crosslinking) agent. Curing agent is an essential additive, whether it is used as adhesive, coating, castable, it is necessary to add curing agent, otherwise the epoxy resin can not cure. The variety of curing agent has a great impact on the mechanical properties, heat resistance, water resistance, corrosion resistance and so on
