O le a le Epoxy Coatings

Epoxy-based coatings e mafai ona lua-vaega faiga (fa'aigoa lua vaega epoxy coating) po'o le fa'aaogaina o se paʻu paʻu. O vaega e lua epoxy coatings o loʻo faʻaogaina mo faiga faʻatinoga maualuga i luga o le uʻamea. O se mea lelei e suitulaga i mea e fa'apipi'iina ai le pa'u pa'u i totonu o fale gaosimea ma ta'avale fa'afetai ona o le maualalo o le fe'avea'i ma le fetaui lelei ma vai fa'atatau. Epoxy powder coating e masani ona faʻaaogaina mo le faʻapipiʻiina o uʻamea i "mea paʻepaʻe" talosaga e pei o faʻavevela ma mea faʻapipiʻi tetele. Epoxy coating o loʻo faʻaaogaina lautele mo le puipuia o le pala o paipa ma mea faʻapipiʻi: i totonu ole suauʻu ma kesi alamanuia, ae faʻapea foʻi mo paipa vai, sima faʻamalosia rebar e taʻu ai ni nai.

O le epoxy o se copolymer lea e maua mai i le toe faʻaogaina o se epoxide (resin) ma se polyamine (faʻamalosi). E lauiloa i latou mo lo latou maualuga maualuga o le pipii, aemaise lava i luga o uʻamea, maualuga vailaʻau ma vevela, ma sili atu le malosi o le faʻaogaina o le eletise. Epoxy formulations o se vaifofo sili ona lelei mo le tele o vaega eletise ma mea tau eletise (fa'ata'ita'iga: faʻapipiʻi faʻapipiʻi, ufimata solder i luga o laupapa matagaluega). Overall epoxy coatings e sili atu le taugata nai lo isi faiga e pei o le Alkyd poʻo le Acrylic, ae o loʻo faʻaalia foi le maualuga o faʻatinoga. I le isi itu epoxy coatings e mafatia i taimi uma i lamepa UV. O lenei vaivaiga e tauia e ala i le faʻaogaina o se faʻapipiʻi puipuia o le UV poʻo le pito i luga
