Epoxy curing agents are used to obtain optimum performance characteristics of epoxy resins by crosslinking with them. The selection of curing agents is totally dependent upon the process and end user requirements. Handling characteristics such as viscosity, pot life, gel time, and physical & chemical properties along with environmental limitations play a crucial role in the manufacturing of epoxy curing agents. Epoxy curing agents are mainly classified as aliphatic amines, polyamides, aromatic amines, anhydride, catalytic, polysulfide, and mercaptans. Each of them have advantages and dis-advantages over the other and for specific requirements
The global epoxy curing market has witnessed substantial growth due to its extensive applications in construction, coatings, adhesives, and electronics among others. High growth in construction activities in both, residential and no-residential sectors is increasing demand for high performance epoxy-based resins.
