Methyltetrahydrophthalic anhydride (MTHPA-EG) is a versatile low cost liquid anhydride hardener.
MTHPA-EG/6K is one of several pre-catalysed versions of MTHPA-EG.
It contains 1-2% BTEAC (N-Benzyl-N, N,N-triethylammonium chloride). This product is specially
formulated to remain liquid during the winter season (typical pour point -20°C to -15°C).
It provides unique characterisics to epoxy cured materials such as high volatage and temperatur
resistance.
It finds use in the coating of wind mill blades and in reinforced plastics, filament winding pro
ducts, construction and sport equipment, laminated sheets as well as in the production of electrical
parts such as capacitors, resistors, transformers, ignition coils.
Specific applications include filament winding, adhesive, potting, casting, encapsulation and vaccum
impregnation.
Typical formulation:
Epoxy: . . . . . . . . . . Bisphenol-A type, epoxy equivalent 190
Cure temperatur: . . 100°C (app. 25 minutes gel time)
Mix compositon:
Epoxy equivalent/anhydride equivalent = 1
Epoxy: . . . . . . . . . 100 phr
Anhydride: . . . . . . 87 phr
