Ujeedada daraasadda cusub waxay ahayd in la falanqeeyo saamaynta ka kooban basecoat iyo dhumucda habdhaqanka farsamada ee nidaamka dhamaystirka alwaaxyada badan ee UV-la daweyn karo.
Joogitaanka iyo sifooyinka qurxinta alwaaxdu waxay ka soo baxaan sifooyinka dahaarka ee lagu dabaqo dusha sare. Xawaarahooda degdega ah, cufnaanta isgoysyada sare iyo adkeysiga sare awgeed, dahaarka UV-la daweyn karo ayaa inta badan doorbida sagxadaha fidsan sida sagxadaha adag, miisaska iyo albaabada. Marka laga hadlayo sagxadaha alwaaxyada adag, dhowr nooc oo ka sii xumaanaya dusha dahaarka ayaa burburin kara aragtida badeecada oo dhan. Shaqada hadda jirta, qaababka UV-la daweyn karo oo leh lammaane monomer-oligomer oo kala duwan ayaa la diyaariyey oo loo adeegsaday sidii gunti gudaha nidaamka dhammaystirka alwaaxyo badan. Iyadoo jaakada sare loogu talagalay inay u adkeyso inta badan culeysyada la isticmaalo, culeysyada laastikada iyo balaastikada ayaa gaari kara lakabyo qoto dheer.
Inta lagu jiro daraasadda, sifooyinka jireed sida celceliska dhererka qaybta aragtida, heerkulka kala-guurka dhalada iyo cufnaanta isku-dhafka ah, filimaanta kali-go'an ee lamaanaha monomer-oligomer ee kala duwan ayaa la baaray. Kadibna, imtixaannada iska caabbinta xoqidda iyo xoqidda ayaa la sameeyay si loo fahmo doorka saldhigyada hoose ee jawaabta farsamada guud ee dahaarka badan. Dhumucdiisuna waxay ku xiran tahay saldhigga loo yaqaan 'basecoat' ayaa la ogaaday in ay saameyn weyn ku leedahay iska caabbinta farsamada ee nidaamka dhamaystirka. Ma jiro xiriir toos ah oo u dhexeeya saldhigga kootada sida filimaan gooni-gooni ah iyo gudaha dahaarka lakabyada badan, iyadoo la tixgelinayo kakanaanta nidaamyadan dhowr dabeecadood ayaa la ogaaday. Nidaam dhammaystiran oo awood u leh inuu kor u qaado caabbinta xoqitaanka guud ee wanaagsan iyo moduleka gelinta wanaagsan ayaa loo helay qaabaynta muujinta dheellitirka u dhexeeya cufnaanta shabakadda iyo bartinimada.
