ʻO ka Methyltetrahydrophthalic anhydride (MTHPA) he pūhui kemika i hāʻule ma lalo o ka māhele o nā anhydride cyclic.Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻōla i nā resins epoxy.Eia kekahi mau pono nui o MTHPA:
1.Curing waiwai: ʻO MTHPA kahi mea lapaʻau maikaʻi no nā resins epoxy, e hāʻawi ana i ka wela maikaʻi a me ke kū'ē kemika.Kōkua ia i ka hoʻololi ʻana i ka resin epoxy wai i mea paʻa, lōʻihi, a me ka thermoset, kūpono ia no nā noi like ʻole.
2.Low viscosity: ʻO ka MTHPA maʻamau ka haʻahaʻa haʻahaʻa i hoʻohālikelike ʻia me nā mea hoʻōla ʻē aʻe, kahi e maʻalahi ai ka lawelawe ʻana a hui pū me nā resins epoxy, hoʻomaikaʻi i ka hana ʻana a me nā hiʻohiʻona noi.
3.Good thermal stability: ʻO ka epoxy i ho'ōlaʻia me ka MTHPA e hōʻike ana i ke kūpaʻa wela maikaʻi, e kūpono ana i nā noi kahi e pono ai ka pale wela.
4..Nā waiwai uila maikaʻi: ʻO nā resins epoxy i hoʻōla ʻia me MTHPA ʻoiai ʻo ka mea hoʻōla e loaʻa pinepine i ka uila makemake.
