Vaongorori vakaona kuti kugadziriswa kwe epoxy acrylate (EA) ne carboxyl-terminated intermediate kunowedzera kuchinjika kwefirimu uye kunoderedza viscosity ye resin. Chidzidzo ichi chinoratidzawo kuti zvinhu zvinoshandiswa hazvidhuri uye zvinowanikwa nyore nyore.
Epoxy acrylate (EA) ndiyo inonyanya kushandiswa neUV-therapy oligomer nekuda kwenguva pfupi yayo yekupora, kuomarara kwayo, kugona kwayo kushandisa michina, uye kugadzikana kwekupisa. Kuti igadzirise matambudziko ekusasimba, kusasimba, uye kusimba kwakanyanya kweEA, UV-therapy epoxy acrylate oligomer ine kusimba kushoma uye kusimba kwakanyanya yakagadzirwa ndokuiswa paUV-therapy coatings. Carboxyl terminated intermediate inowanikwa ne anhydride ne diol yakashandiswa kugadzirisa EA kuti ivandudze kusimba kwefirimu rakagadzirwa, uye kusimba kwacho kwakagadziriswa kuburikidza nehurefu hwekabhoni cheni ye diols.
Nekuda kwehunhu hwadzo hwakanaka, ma epoxy resins anoshandiswa zvakanyanya muindasitiri yekupeta kupfuura chero rimwe boka rema binder. Mubhuku ravo idzva rekutarisa rinonzi "Epoxy Resins", vanyori Dornbusch, Christ naRasing vanotsanangura hwaro hwemakemikari eboka re epoxy uye vanoshandisa mafomura chaiwo kutsanangura kushandiswa kwema epoxy ne phenoxy resins muma coatings emaindasitiri - kusanganisira kudzivirira ngura, coatings pasi, poda coatings uye coatings yemukati yemakani.
Kusviba kweresin kwakaderedzwa nekutsiva zvishoma E51 ne binary glycidyl ether. Zvichienzaniswa ne unmodified EA, viscosity yeresin yakagadzirwa muchidzidzo ichi inoderera kubva pa29800 kusvika pa13920 mPa s (25°C), uye kuchinjika kwefirimu rakacheneswa kunowedzera kubva pa12 kusvika pa1 mm. Zvichienzaniswa ne modified EA inowanikwa mukutengeserana, zvinhu zvakashandiswa muchidzidzo ichi zvinodhura zvishoma uye zviri nyore kuwana kana tembiricha ye reaction iri pasi pe130°C, uchishandisa nzira iri nyore yekugadzira, uye pasina organic solvents.
