What Is an Epoxy Hardener? Epoxy hardeners, also known as curing agents, are reactive chemicals that crosslink with epoxy resins to form a thermoset polymer network. Without a hardener, epoxy resin remains a viscous liquid and never fully cures.

An epoxy resin hardener is a chemical agent that reacts with epoxy resin to initiate the curing process. This reaction transforms the liquid resin into a solid, durable material by creating a strong polymer network.

The amount and type of hardener needed depends on the type of epoxy resin being used. Do-it-yourself epoxy paints (different from industrial-grade floor coatings) are often water-based and rely mainly, if not exclusively, on evaporation to harden and dry the final product.

Epoxy resins typically consist of two main components: the epoxy resin itself and the hardener. When these two components are combined in the correct proportions, a chemical reaction begins, forming a three-dimensional network of interconnected polymer chains.
