Product Description

Isophorone Diamine (IPDA) is a specialty aliphatic diamine derived from the isophorone family and widely used as a reactive curing agent in high-performance polymer systems. It is typically produced through the hydrogenation and subsequent amination of isophorone or its intermediates, yielding a highly pure compound suitable for advanced industrial applications. IPDA is supplied as a clear, low-viscosity liquid with a characteristic amine odor and offers excellent reactivity toward epoxy resins and isocyanates.

IPDA is valued for its outstanding chemical resistance, UV stability, and mechanical strength-enhancing characteristics. Its cycloaliphatic structure provides superior color stability, low yellowing tendencies, and strong durability under harsh environmental conditions. These attributes make IPDA essential in producing long-lasting coatings, adhesives, sealants, and specialty polyurethane systems that require high transparency, structural integrity, and resistance to degradation.

Major application areas include epoxy curing for protective industrial coatings, marine and flooring systems, and electrical encapsulation materials. IPDA also plays a key role in polyurethane elastomers, composite resins, construction adhesives, and high-performance engineering polymers. Its combination of robust functional performance, reliable crosslinking behavior, and compatibility with demanding industrial environments makes Isophorone Diamine a critical building block across coatings, automotive, electronics, and construction sectors.
