Gudun polyester mara kyau shine mafi yawan amfani da nau'in guduro na thermosetting, wanda shine gabaɗaya mahaɗin polymer na layi tare da ester bonds da unsaturated biyu bond waɗanda aka samar ta hanyar condensation na dicarboxylic acid unsaturated tare da diols ko cikakken dicarboxylic acid tare da diols unsaturated. Yawancin lokaci, ana aiwatar da halayen haɓakar polyester a 190-220 ℃ har sai an kai ƙimar acid ɗin da ake tsammani (ko danko). Bayan an kammala aikin narkar da polyester, ana ƙara wani adadin vinyl monomer yayin zafi don shirya ruwa mai ɗanɗano. Wannan maganin polymer ana kiransa resin polyester unsaturated.
Gudun polyester mara kyau ya sami babban nasara a fannonin masana'antu da yawa, kamar kera jiragen ruwa da jiragen ruwa a wasannin ruwa. Wannan polymer ya kasance koyaushe a cikin jigon juyin juya halin gaskiya a cikin masana'antar ginin jirgi, saboda yana iya samar da kyakkyawan aiki da sassauci sosai a cikin amfani.
Hakanan ana amfani da resin polyester mara kyau a cikin masana'antar kera saboda ƙirar ƙira, nauyi mai sauƙi, ƙarancin tsarin, da ƙarancin ƙarfin injina.
Ana kuma amfani da wannan kayan a cikin gine-gine, musamman wajen kera kayan girki, murhu, fale-falen rufin rufi, kayan wanka, da bututu da tankunan ruwa.
Aikace-aikace na resin polyester unsaturated sun bambanta. Gudun polyester a gaskiya yana wakiltar ɗaya daga cikin cikakke
