What is Isophorone diamine?
Isophorone diamine (CAS 2855-13-2), commonly known as IPDA, is a cycloaliphatic diamine used as a curing agent and building block in high-performance polymer systems.
Where is Isophorone diamine used?
- Epoxy coatings for automotive and aerospace: UV stability and chemical resistance
- Structural adhesives and sealants in construction and transportation: flexibility and durability under mechanical stress
- Polyurea and polyurethane synthesis: elastomers and casting compounds for industrial flooring, protective linings and electronic encapsulation
- Printing and packaging: laminating adhesives with low yellowing and adhesion to film substrates
- Its low reactivity at ambient temperatures combined with rapid cure at elevated temperatures makes it a controlled hardener for demanding formulations.
Commercial specifications
- Purity typically 99% or higher
- Low-color or low-viscosity variants offered for coating and adhesive formulations with strict appearance requirements
