MTHPA is mainly used as a curing agent for epoxy resins. It has a low tendency to absorb moisture from the air and zero or minimal formation of carbon dioxide when mixed with tertiary amine accelerators.

MTHPA can be easily blended with various liquid resins providing stable, low viscous mixture and long pot life. It is widely used for Casting or Potting, Impregnation, Pultrusion, Lamination and Filament winding process. In the field of fiber reinforced plastics, it is used for filament winding products, such as FRP pipes for oil, poles and sport appliance, it is also used for laminated sheets, printed circuit boards, switch gears.

MTHPA has excellent insulating properties to electrical parts such as: capacitors, resistors, wiring parts, transformers, ignition coils and motor.
