O le unsaturated polyester resin o le ituaiga thermosetting resin e sili ona faʻaaogaina, o se mea masani lava o se polymer linear ma ester bonds ma unsaturated double bonds e fausia e ala i le condensation o le unsaturated dicarboxylic acid ma diols poʻo le saturated dicarboxylic acid ma unsaturated diols. E masani lava, o le polyester condensation reaction e faia i le 190-220 ℃ seʻia oʻo ina ausia le acid value (poʻo le viscosity) e faʻamoemoeina. A maeʻa le polyester condensation reaction, e faʻaopoopoina se aofaʻi patino o le vinyl monomer aʻo vevela e saunia ai se vai mafiafia. O lenei polymer solution e taʻua o le unsaturated polyester resin.
Ua ausia e le unsaturated polyester resin le manuia tele i le tele o vaega tau alamanuia, e pei o le gaosiga o le windsurfing ma va'a la'u i ta'aloga i le vai. O lenei polymer sa avea pea ma totonugalemu o le suiga moni i le pisinisi fau va'a, aua e mafai ona maua ai le fa'atinoga sili ona lelei ma le maualuga tele o le fetu'una'i i le fa'aaogaina.
E masani fo'i ona fa'aaogaina resins polyester unsaturated i le alamanuia o ta'avale ona o le fetu'una'i o latou mamanu, mama, tau maualalo o le faiga, ma le malosi fa'ainisinia maualalo.
O lenei mea e faʻaaogaina foʻi i fale, aemaise lava i le gaosiga o mea kuka, ogaumu, taʻele o taualuga, mea faʻaoga mo le faletaʻele, faʻapea foʻi ma paipa ma tane vai.
E eseese faʻaoga o le unsaturated polyester resin. O le mea moni, o le polyester resins o se tasi lea o mea e sili ona lelei.
o mea fa'aputu e fa'aaogaina i le tele o alamanuia. O mea e sili ona taua, fa'apea fo'i ma mea o lo'o fa'aalia i luga, o:
* Mea fa'apipi'i
* Vali laupapa
* Paneli fa'apipi'i mafolafola, paneli fa'apipi'i, paneli fa'apipi'i
* Ufiufi gel mo va'a, ta'avale ma mea fa'aoga faleta'ele
* Mea vali lanu, mea fa'atumu, stucco, putty ma mea fa'amau vaila'au
* Mea fa'apipi'i e tineia e ia lava
* Kuata, ma'a ma sima fa'apitoa
