Latent at room temperature — enables extended pot life and ambient storage stability.
Activates rapidly upon heating — delivers efficient epoxy resin curing above 120 °C.
Low volatility and low odor — supports safer handling and improved workplace air quality.
Excellent compatibility with standard diglycidyl ether of bisphenol-A (DGEBA) resins.
Yields high glass transition temperature (Tg) cured networks with superior thermal and mechanical performance.
Aerospace composite prepregs requiring precise cure scheduling and out-time control.
Electrical laminates for printed circuit boards (PCBs) demanding high Tg and dimensional stability.
Automotive under-hood components requiring resistance to sustained thermal cycling.
Wind turbine blade structural adhesives and matrix resins for elevated service temperatures.
High-performance tooling and casting compounds where low exotherm and controlled reactivity are critical.
