Irangi ritaziba rya polyurethane n'irangi ritaziba rya acrylic ni irangi risanzwe ritaziba. Rifite itandukaniro rinini mu miterere y'ibikoresho, imiterere y'inyubako n'imirima ikoreshwa.
Ubwa mbere, mu bijyanye n'imiterere y'ibikoresho, irangi rya polyurethane ridashobora kuvoma rigizwe na resin ya polyurethane, imiti isukura n'ibindi birungo, kandi rifite ubushobozi bwo gukomera no kwihanganira ikirere. Irangi rya acrylic ridashobora kuvoma rigizwe na resin ya acrylic, ibintu biyizuza n'ibindi birungo. Rirangwa no kuma vuba no gukora neza filime.
Icya kabiri, mu bijyanye n'imiterere y'ubwubatsi, irangi rikoreshwa muri polyurethane ritaziba ubusanzwe risaba urwego rwo hejuru rwa tekiniki mu gihe cyo kubaka, rigomba kubakwa ahantu heza kurushaho, kandi rifite ibisabwa byinshi mu gutunganya ubuso bw'ibanze. Irangi rikoreshwa muri acrylic ritaziba ryoroshye gukora kandi rishobora kubakwa mu bihe bisanzwe, kandi rifite ibisabwa bike ku buso bw'ibanze.
Byongeye kandi, ku bijyanye n'imirima ikoreshwa, kubera ko irangi ritaziba rya polyurethane rifite ubushobozi bwo gukomera no kwihanganira ikirere, rikwiriye ahantu hakenera uburinzi bw'igihe kirekire kandi hashobora kubaho stress nyinshi, nko ku bisenge, mu mazu yo munsi y'ubutaka, n'ibindi. Irangi ritaziba rya acrylic rikwiriye mu nyubako rusange kandi rishobora kubakwa vuba. Rikwiriye rimwe na rimwe aho igihe cyo kubaka ari gito kandi hakenewe gukwirakwizwa vuba.
Hari itandukaniro rigaragara hagati y’imyambaro ya polyurethane idapfa amazi n’imyambaro ya acrylic idapfa amazi mu bijyanye n’imiterere y’ibikoresho, imiterere y’inyubako n’imirima ikoreshwa. Mbere yo kubaka, imashini zikwiye zidapfa amazi zigomba gutoranywa hakurikijwe ibyo umushinga ukeneye.
