Methylcyclohexanediamine is widely used as a curing agent in the production of epoxy resins, particularly in coatings, adhesives, and composites. Its ability to enhance the mechanical and thermal properties of epoxy systems makes it valuable in industries such as automotive, aerospace, and construction. It is also employed in the synthesis of polyamide resins, which are used in coatings and inks due to their durability and chemical resistance. Additionally, it serves as an intermediate in the manufacture of corrosion inhibitors and surfactants, contributing to applications in industrial cleaning and metal treatment processes. Its versatility and effectiveness in various chemical processes make it a key component in multiple industrial applications.
