Ko te Glycidyl Methacrylate (GMA), he monomer mahi-epoxy ahurei, kei te whai wāhi tonu ki ngā momo ahumahi nā ōna āhuatanga matū motuhake. Nā te noho tahi o ngā rōpū epoxy me te methacrylate i roto i tōna hanganga ngota, ka taea e te GMA te whakahohe i te tauhohenga tino pai e kore ai e hiahiatia i roto i te whakarerekētanga rauemi.
I roto i te umanga paninga, ka whai wāhi a GMA ki te hanga paninga kiriata mahi-teitei. Ka tauhohe tōna rōpū epoxy ki ngā rōpū mahi i roto i ētahi atu wāhanga, ka whakarei ake i te piri o te paninga ki ngā papa, me tōna ātete ki ngā matū me te pakū. Mā tēnei ka mau tonu te pakari o ngā hua paninga ahakoa i roto i ngā taiao uaua.
Mō ngā piripiri me ngā hiri, he mea nui te GMA hei whakarerekētanga. Ka whakapai ake i te kaha o te here i waenga i ngā rauemi rerekē, tae atu ki ngā konganuku, ngā kirihou, me ngā mea whakakotahi, me te whakanui ake i te pumau o te waiariki o te hanganga. Nā tēnei maha o ngā whakamahinga ka waiho hei whiringa pai mō ngā tono e hiahia ana kia piri pono.
Hei tāpiritanga, i roto i te hanga rauemi polymeric, ka āwhina a GMA i te copolymerization me ētahi atu monomers. Ko ngā polymers e hua mai ana ka whakaatu i ngā āhuatanga miihini taurite me te ātete matū, e mahi ana i ngā rāngai mai i te hanga wāhanga motuka ki te takai hiko.
Hei poraka hanga matū taketake, ko te kaha o GMA ki te whakarei ake i te mahi rauemi e whakaatu ana i tōna hiranga pumau puta noa i ngā whenua hanga kanorau.
