Cov coatings siv rau xim -coated coils feem ntau muaj plaub yam: resins (zaj duab xis- tsim cov khoom), pigments, solvents, thiab additives. Feem ntau siv primers muaj xws li epoxy, polyester, acrylic, thiab polyurethane; qhov kev xaiv tshwj xeeb yog feem ntau txiav txim siab los ntawm cov khoom tsim daim ntawv thov, kev ua tiav, thiab kev sib raug zoo nrog cov topcoat. Cov zaj duab xis tuab ntawm primer yog li ntawm 5 txog 7 microns. Epoxy primers muab cov adhesion zoo thiab tshuaj tiv thaiv; polyester primers muab superior adhesion thiab yooj; acrylic primers muaj cov ntsiab lus organic hnyav; thiab polyurethane primers zoo nyob rau hauv ob qho tib si tshuaj tiv thaiv thiab yooj.
Nrog kev nce qib hauv thev naus laus zis, siab-kev ua tau zoo, eco- cov hmoov zoo phooj ywg-coated coils tau tshwm sim. Cov khoom siv no siv cov txheej txheem electrostatic txheej uas cov txheej txheem polymeric hmoov txheej yog txau rau ntawm qhov chaw substrate thiab tom qab ntawd kho ntawm qhov kub thiab txias los tsim cov txheej txheej tuab heev. Xim-coated coils uas tsim los ntawm cov txheej txheem no muaj ntau qhov zoo, suav nrog kev tiv thaiv corrosion tshwj xeeb (nrog rau cov kua qaub thiab alkali tsis kam mus txog 5 mus rau 6 npaug ntawm cov khoom siv), xoom formaldehyde emissions, Class A2 hluav taws kub tsis kam, thiab huab cua tiv thaiv uas phim lub neej kev pab cuam ntawm lub tsev nws tus kheej. Tsis tas li ntawd, txheej txheej tuaj yeem siv rau hauv ib qho dhau los kom ua tiav qhov tuab ntawm 35 txog 200 microns, yog li ua kom yooj yim rau kev ua haujlwm rau kev lag luam hauv qab xws li kev tsim khoom siv hauv tsev.
