Abashakashatsi basanze guhindura epoxy acrylate (EA) hamwe n’igice cya karubokisili cyavuyemo umwuka byongera ubworoherane bwa firime kandi bikagabanya ubukana bwa resin. Ubushakashatsi kandi bwerekana ko ibikoresho fatizo bikoreshwa bihendutse kandi biboneka ku buryo bworoshye.
Epoxy acrylate (EA) niyo oligomer ivurwa cyane na UV kubera ko imara igihe gito, ifite ubukana bwinshi bwo gutwikira, ifite imiterere myiza ya mekanike, kandi ikagira ubushyuhe burambye. Kugira ngo hakemurwe ibibazo byo kugorama cyane, kugorama guke, no kugorama cyane kwa EA, oligomer ya epoxy acrylate ivurwa na UV ifite ubukana buke kandi ifite ubworoherane bwinshi yarateguwe kandi ishyirwa ku bipfundikizo bivurwa na UV. Carboxyl terminated intermediate yabonetse binyuze mu gukora anhydride na diol yakoreshejwe mu guhindura EA kugira ngo inoze ubworoherane bwa filamenti ivurwa, kandi ubworoherane bwahinduwe binyuze mu burebure bw'uruhererekane rwa diols.
Bitewe n'imiterere yazo idasanzwe, epoxy resins ikoreshwa cyane mu nganda zisiga amarangi kurusha izindi nganda zose. Mu gitabo cyabo gishya cyitwa "Epoxy Resins", abanditsi Dornbusch, Christ na Rasing basobanura iby'ibanze bya chimie y'itsinda rya epoxy kandi bakoresha uburyo bwihariye bwo gusobanura ikoreshwa rya epoxy na phenoxy resins mu nganda zisiga amarangi - harimo kurinda ingese, gusiga hasi, gusiga ifu n'udupira tw'imbere mu macupa.
Ubushyuhe bwa resin bwagabanutse bitewe no gusimbuza igice E51 na binary glycidyl ether. Ugereranyije na EA idahinduwe, ubushyuhe bwa resin yateguwe muri ubu bushakashatsi bugabanuka kuva kuri 29800 kugera kuri 13920 mPa s (25°C), kandi ubworoherane bwa firime yavuwe bwiyongera kuva kuri 12 kugeza kuri 1 mm. Ugereranyije na EA yahinduwe iboneka ku isoko, ibikoresho fatizo byakoreshejwe muri ubu bushakashatsi birahendutse kandi biroroshye kubibona iyo ubushyuhe bwa reaction buri munsi ya 130°C, hakoreshejwe uburyo bworoshye bwo gukora synthesis, kandi nta binyabutabire by’umwimerere bihari.
