Ndị na-eme nchọpụta chọpụtara na ngbanwe nke epoxy acrylate (EA) na etiti carboxyl kwụsịrị na-abawanye mgbanwe nke ihe nkiri ahụ ma na-ebelata viscosity nke resin. Ọmụmụ ihe ahụ gosikwara na akụrụngwa eji eme ihe adịghị ọnụ ma dịkwa ngwa ngwa.
Epoxy acrylate (EA) bụ oligomer UV-curable a na-ejikarị eme ihe ugbu a n'ihi oge ọgwụgwọ ya dị mkpụmkpụ, ike mkpuchi dị elu, akụrụngwa akụrụngwa dị mma, yana nkwụsi ike ọkụ. Iji dozie nsogbu nke nnukwu brittleness, adịghị mma mgbanwe, na elu viscosity nke EA, UV-curable epoxy acrylate oligomer na obere viscosity na elu mgbanwe dị njikere ma tinye na UV-curable mkpuchi. A na-eji carboxyl kwụsịrị etiti nke enwetara site na mmeghachi omume nke anhydride na diol iji gbanwee EA iji meziwanye mgbanwe nke ihe nkiri a gwọrọ, na mgbanwe mgbanwe na-agbanwe site na ogologo nke carbon carbon nke diols.
N'ihi njirimara ha pụtara ìhè, a na-eji resin epoxy eme ihe na ụlọ ọrụ mkpuchi karịa ihe fọrọ nke nta ka ọ bụrụ klaasị ọ bụla ọzọ. N'akwụkwọ ntụaka ọhụrụ ha bụ "Epoxy Resins", ndị dere Dornbusch, Christ na Rasing na-akọwa ihe ndị bụ isi nke kemịkalụ nke ìgwè epoxy ma jiri usoro dị iche iche kọwaa iji epoxy na phenoxy resins na mkpuchi ụlọ ọrụ - gụnyere nchebe corrosion, mkpuchi ala, mkpuchi ntụ ntụ na mkpuchi ime ụlọ.
E belatara viscosity resin site na iji ọnụọgụ abụọ glycidyl ether dochie E51. E jiri ya tụnyere EA na-enweghị mgbanwe, viscosity nke resin a kwadebere na ọmụmụ ihe a na-ebelata site na 29800 ruo 13920 mPa s (25 ° C), na mgbanwe nke ihe nkiri a gwọrọ na-abawanye site na 12 ruo 1 mm. E jiri ya tụnyere EA emezigharịrị azụmaahịa, akụrụngwa eji eme ihe n'ọmụmụ ihe a dị ọnụ ala ma dị mfe iji nweta okpomọkụ mmeghachi omume n'okpuru 130 Celsius C, na-eji usoro njikọ dị mfe, na enweghị ihe mgbaze organic.
