Ko ngā oligomer he ngota ngota e tito ana i ētahi waeine e tāruarua ana, ā, koinei ngā wāhanga matua o ngā waituhi UV-whakaora. Ko ngā waituhi UV-whakaora he waituhi ka taea te whakamaroke me te whakamaroke tonu mā te whakaatu ki te hihi ultraviolet (UV), e pai ai mō ngā tukanga tā me te paninga tere-teitei. He mahi nui tā ngā oligomer ki te whakatau i ngā āhuatanga me te mahi o ngā waituhi UV-whakaora, pērā i te matotoru, te piri, te ngāwari, te pakari, me te tae.
E toru ngā momo matua o ngā oligomer UV-curable, arā, ko ngā epoxy acrylates, ko ngā polyester acrylates, me ngā urethane acrylates. He āhuatanga me ngā whakamahinga motuhake tō ia momo, i runga i te momo papa, te tikanga whakamaroke, me te kounga e hiahiatia ana o te hua whakamutunga.
Ko ngā epoxy acrylates he oligomers kei roto i ō rātou tuara he rōpū epoxy, me ngā rōpū acrylate kei ō rātou pito. E mōhiotia ana rātou mō tō rātou kaha tauhohenga teitei, te matotoru iti, me te ātete matū pai. Heoi, he ngoikoretanga anō hoki ō rātou, pērā i te ngoikore o te ngāwari, te iti o te piri, me te āhua kōwhai. He pai ngā epoxy acrylates mō te tā ki runga i ngā papa pakari, pērā i te konganuku, te karāhe, me te kirihou, me ngā tono e hiahia ana kia kanapa me te pakeke teitei.
Ko ngā acrylates polyester he oligomers kei roto i ō rātou tuara he rōpū polyester, me ngā rōpū acrylate kei ō rātou pito. E mōhiotia ana rātou mō tō rātou tauhohenga ngawari, te iti o te whakahekenga, me te ngāwari pai. Heoi, he ngoikoretanga anō hoki ō rātou, pērā i te matotoru teitei, te iti o te ātete matū, me te tukunga haunga. He pai ngā acrylates polyester mō te tā ki runga i ngā papa ngāwari, pērā i te pepa, te kiriata, me te papanga, me ngā tono e hiahia ana kia pai te piri me te ngāwari.
Ko ngā urethane acrylates he oligomers kei roto i ō rātou tuara he rōpū urethane, me ngā rōpū acrylate kei ō rātou pito. E mōhiotia ana rātou mō tō rātou tauhohenga iti, te matotoru teitei, me te ngāwari pai rawa atu. Heoi, he ngoikoretanga anō hoki ō rātou, pērā i te utu nui, te aukati hāora teitei, me te tere whakaora iti. He pai ngā urethane acrylates mō te tā ki runga i ngā papa rerekē, pērā i te rakau, te hiako, me te rapa, me ngā tono e hiahia ana kia roa te mau me te ātete ki te pakū.
Hei whakamutunga, he mea nui ngā oligomer mō te hanganga me te mahi a ngā waituhi UV-whakaora, ā, ka taea te whakarōpū kia toru ngā akomanga matua, arā, ko ngā epoxy acrylates, ko ngā polyester acrylates, me ngā urethane acrylates. He painga me he ngoikoretanga tō ia akomanga, i runga i te tono me te papa. He tukanga tonu te whanaketanga o ngā oligomer me te waituhi UV, ā, kei te tūhuratia ngā momo oligomer hou me ngā tikanga whakaora hei whakatutuki i ngā hiahia e piki haere ana o te umanga waituhi.
