Intumescent coatings imhando yezvinhu zvisingapindi moto izvo zvinokura patembiricha yepamusoro kuita insulating layer. Izvo zvinoshandiswa zvakanyanya mukudzivirira moto kune zvivakwa, ngarava, uye maindasitiri emidziyo. Flame retardants, seyakakosheswa zvimisikidzo, inogona kuvandudza zvakanyanya zvimisikidzo zvemoto zvejasi. Pasi pemamiriro ekupisa kwepamusoro, zvinodzoreredza murazvo zvinoburitsa magasi anert kuburikidza nekuita kwemakemikari, kuderedza huwandu hweokisijeni, uye kukurudzira kuwedzera kwekuputira kuumba dense carbonized layer, zvinonyatso kupatsanura kupararira kwekupisa nemirazvo.
Zvinowanzo shandiswa murazvo retardants zvinosanganisira phosphorus, nitrogen, uye halogen makomponi. Phosphorus flame retardants inononoka kupisa nekugadzira phosphate protective layer; nitrogen flame retardants inoburitsa nitrogen kuderedza magasi anopisa; uye halogen flame retardants inovhiringidza kutsva kweketani nekutora mahara radicals. Mumakore achangopfuura, zvigadziriso zvemoto zvinodzoreredza (senge halogen-isina moto retardants) zvishoma nezvishoma zvave nzvimbo yekutsvagisa nekuda kwekuderera kwehupfu uye kushamwaridzana kwezvakatipoteredza.
Muchidimbu, kushandiswa kwemurazvo retardants mune intumescent coatings kwete chete kunatsiridza zvivakwa zvemoto, asi zvakare kunopa yakavimbika chengetedzo yekuvaka kuchengetedza. Mune ramangwana, nekuvandudzwa kwezvinodiwa zvekuchengetedza kwezvakatipoteredza, zvinobudirira uye zvakasvibira murazvo zvinodzoreredza zvichave nhungamiro yakakosha yekusimudzira indasitiri.
