Methyltetrahydrophthalic anhydride (MTHPA) ndi mankhwala omwe amagwera pansi pa gulu la cyclic anhydrides. Amagwiritsidwa ntchito makamaka ngati machiritso mu epoxy resins. Nazi zina mwazabwino za MTHPA:
1.Kuchiritsa katundu: MTHPA ndi mankhwala othandiza a epoxy resins, kupereka kutentha kwakukulu ndi kukana mankhwala. Imathandizira kusintha utomoni wa epoxy wamadzimadzi kukhala chinthu cholimba, chokhazikika, komanso cha thermoset, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zosiyanasiyana.
2.Low viscosity: MTHPA imakhala ndi kukhuthala kochepa poyerekeza ndi othandizira ena ochiritsa, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsira ntchito ndi kusakaniza ndi epoxy resins, kuwongolera machitidwe ndi ntchito.
3.Kukhazikika kwabwino kwa kutentha: Epoxy yochiritsidwa ndi MTHPA imasonyeza kukhazikika kwabwino kwa kutentha, ndikupangitsa kuti ikhale yoyenera kwa mapulogalamu omwe kutentha kuli kofunikira.
4..Zabwino zamagetsi: Ma epoxy resin ochiritsidwa ndi MTHPA monga machiritso nthawi zambiri amakhala ndi magetsi ofunikira.
