Ndị nchọpụta chọpụtara na mgbanwe nke epoxy acrylate (EA) na carboxy-endated intermediate na-eme ka ihe nkiri ahụ dịkwuo mfe ma belata viscosity nke resin. Nnyocha ahụ gosikwara na ihe ndị e ji mee ihe adịghị ọnụ ala ma dịkwa mfe ịnweta.
Epoxy acrylate (EA) bụ oligomer UV a na-agwọkarị nke ọma ugbu a n'ihi obere oge ọgwụgwọ ya, ike mkpuchi ya dị elu, ihe onwunwe igwe dị mma, na nkwụsi ike okpomọkụ. Iji dozie nsogbu nke nnukwu mgbawa, enweghị mgbanwe, na nnukwu viscosity nke EA, e kwadebere ma tinye epoxy acrylate oligomer UV a na-agwọ nke nwere obere viscosity na nnukwu mgbanwe na mkpuchi UV a na-agwọ. Ejiri carboxyl nke anhydride na diol nwetara gbanwee EA iji melite mgbanwe nke ihe nkiri a gwọrọ, a na-agbanwekwa mgbanwe ahụ site na ogologo nke carbon yinye diols.
N'ihi ihe ndị pụrụ iche ha nwere, a na-ejikarị resin epoxy eme ihe n'ụlọ ọrụ mkpuchi karịa ihe fọrọ nke nta ka ọ bụrụ ụdị ihe mgbochi ọ bụla ọzọ. N'akwụkwọ ntụaka ọhụrụ ha bụ "Epoxy Resins", ndị dere akwụkwọ bụ Dornbusch, Christ na Rasing kọwara ihe ndị bụ isi gbasara kemistri nke otu epoxy ma jiri usoro pụrụ iche kọwaa ojiji nke resin epoxy na phenoxy na mkpuchi ụlọ ọrụ mmepụta ihe - gụnyere nchedo nchara, mkpuchi ala, mkpuchi ntụ ntụ na mkpuchi ite dị n'ime.
E belatara viscosity nke resin site na iji obere glycidyl ether dochie E51. Ma e jiri ya tụnyere EA a na-agbanwebeghị agbanwe, viscosity nke resin a kwadebere na nnyocha a na-ebelata site na 29800 ruo 13920 mPa s (25°C), mgbanwe nke ihe nkiri a gwọrọ na-abawanye site na 12 ruo 1 mm. Ma e jiri ya tụnyere EA a gbanwere n'ahịa, ihe eji eme ihe na nnyocha a dị ọnụ ala ma dị mfe inweta ya na okpomọkụ mmeghachi omume dị n'okpuru 130°C, site na iji usoro njikọta dị mfe, na enweghị ihe mgbaze organic.
