A hardener is a curing agent that reacts with a resin and forms a crosslinking polymer by using a catalyst, which initiates resin polymerization. Amine hardeners are the most used epoxy resin types, like aliphatic amines, aromatic amines, and cycloaliphatic amines. The amines and acid anhydrides are the most used hardeners. Whereas aliphatic amines react rapidly at room temperature, aromatic amine hardeners impart higher thermal stability and improved chemical resistance. Depending upon the hardener used, the reaction and chemistry of the process change and align.
The growing demand for high-performance epoxy-based coatings and adhesives across various industries such as construction, automotive, and aerospace. They are in high demand due to the excellent properties offered by the hardeners, such as chemical resistance, durability, and mechanical strength, which makes them essential in applications that require long-term structural integrity.
Rapid industrialization and infrastructural development in the emerging economies boost the consumption of the amine hardeners, which results in an increasing demand.
