Polymeric prepolymer yog ib feem tseem ceeb uas txiav txim siab qhov ua tau zoo ntawm UV txheej txheej txheej. Nws yog qhov tseem ceeb tshaj plaws ntawm UV number case thiab cov khoom tsim ua zaj duab xis. Nws qhov kev ua tau zoo yog lub luag haujlwm tseem ceeb hauv txheej txheem kho thiab cov yam ntxwv ntawm cov kua nplaum kho. Nws yog feem ntau cais raws li tus qauv pob txha. Cov qauv pob txha cuam tshuam rau qhov nyuaj, kev sib txhuam tsis kam, adhesion, lub teeb tsis kam, tshuaj tsis haum thiab dej tsis kam ntawm txheej.
Cov txheej txheem, cov oligomers yog cov uas muaj cov tshuaj molecular tsawg uas muaj" C=C" tsis muaj kev sib txuas ob zaug, xws li acrylic acyl, methacryloyl, vinyl, allyl, thiab lwm yam. Nyob rau tib qhov xwm txheej, lub teeb kho kom nrawm ntawm acryloyl pab pawg yog nrawm tshaj, yog li feem ntau oligomers yog acrylic resin.
