Ko te Methyltetrahydrophthalic anhydride (MTHPA) he matū e taka ana ki raro i te kāwai o ngā cyclic anhydrides. Ko te nuinga o te wā ka whakamahia hei rongoā i roto i ngā kapia epoxy. Anei ētahi o ngā painga matua o te MTHPA:
1. Ngā āhuatanga whakamaroke: He matū whakamaroke whai hua te MTHPA mō ngā kapia epoxy, e whakarato ana i te ātete wera me te matū tino pai. Ka āwhina i te huri i te kapia epoxy wai hei rauemi totoka, pakari, me te werawera, kia pai ai mō ngā mahi maha.
2. He iti te matotoru: He iti ake te matotoru o te MTHPA i ērā atu matū whakamaroke, ā, he māmā ake te whakamahi me te whakaranu ki ngā kapia epoxy, ka pai ake te tukatuka me ngā āhuatanga tono.
3. He pai te pumau o te wera: He pai te pumau o te wera o te epoxy kua rongoatia me te MTHPA, ā, he pai mō ngā tono e hiahiatia ana te ātete ki te pāmahana.
4..Ngā āhuatanga hiko pai: He maha ngā wā ka hiahiatia he hiko e hiahiatia ana i roto i ngā kapia epoxy kua whakamaroketia me te MTHPA hei kaiwhakamāro.
