Isophorondiamine

Product Overview

Isophoronediamine (IPDA), CAS 2855-13-2, is a premium aliphatic cycloaliphatic diamine widely recognized as one of the highest-performance epoxy curing agents available. As a pale yellow liquid with a boiling point of 217°C, IPDA delivers exceptional weathering resistance, chemical resistance, and mechanical strength to cured epoxy systems.

Derived from the hydrogenation of isophorone, IPDA's unique cyclohexane backbone structure imparts outstanding flexibility, UV stability, and thermal stability to the final polymer network. It is a key intermediate in the production of isophorone diisocyanate (IPDI, CAS 4098-71-9), polyurea elastomers, and high-performance coatings.

Key Applications

• Epoxy Coatings & Flooring: Premium curing agent for industrial anticorrosion coatings, flooring systems, marine paints, and protective linings — delivers outstanding adhesion, chemical resistance, and weather durability; enables room-temperature curing ideal for on-site application
• Adhesives & Sealants: Structural adhesives for construction, wind turbine blade bonding, and architectural sealants — high bond strength with exceptional aging resistance and long-term reliability under extreme environmental conditions
• Composite Materials: Curing agent for carbon fiber and glass fiber reinforced composite matrices — produces high-strength, high-toughness composites with superior heat resistance; critical for aerospace, automotive lightweighting, and sporting goods
• Polyurea Elastomers: Chain extender for polyurea prepolymer systems — imparts excellent mechanical properties, abrasion resistance, and chemical resistance; used in waterproofing coatings, wear-resistant linings, and truck bed liners
• Electronic Encapsulation: LED potting compounds and electronic component encapsulation materials — provides thermal stability and moisture resistance for sensitive electronics
• 3D Printing Resins: Raw material for high-performance photocurable resins in industrial additive manufacturing
• Waterborne Coatings: Curing agent for environmentally friendly water-based epoxy coatings — driven by tightening VOC regulations globally

Product Features

• Superior Weathering Resistance: Aliphatic structure prevents yellowing under UV exposure — ideal for outdoor coatings and clear finishes
• Excellent Chemical Resistance: Cured epoxy systems resist acids, alkalis, solvents, and corrosive environments
• High Thermal Stability: Heat deflection temperature (HDT) of cured systems exceeds 150°C, suitable for demanding industrial applications
• Outstanding Flexibility: Cyclohexane backbone provides impact resistance and toughness without sacrificing hardness
• Room Temperature Curing: No baking required — enables convenient field application and reduces energy costs
• Low Viscosity: Easy to handle and mix with epoxy resins, ensuring uniform curing and eliminating voids
• Key IPDI Precursor: Direct feedstock for isophorone diisocyanate production, linking to high-value polyurethane markets
• Regulatory Compliance: Suitable for REACH-registered applications; increasingly preferred over aromatic alternatives for low-VOC formulations
