Injongo yophando olutsha yayikukuhlalutya impembelelo yokwakheka kwe-basecoat kunye nobukhulu bayo kwindlela esebenza ngayo inkqubo yokugqiba iinkuni enezitezi ezininzi enokunyangeka nge-UV.
Ukuqina kunye neempawu ezintle zomgangatho womthi zivela kwiimpawu zomphezulu osetyenziswa kumphezulu wawo. Ngenxa yesantya sawo sokupholisa ngokukhawuleza, uxinano oluphezulu lokudibanisa kunye nokuqina okuphezulu, iingubo ezinyangwa yi-UV zihlala zikhethwa kwiindawo ezithe tyaba ezifana nomgangatho womthi onzima, iitafile kunye neengcango. Kwimeko yomgangatho womthi onzima, iintlobo ezahlukeneyo zokonakala kumphezulu womphezulu womphezulu womphezulu zinokuphazamisa umbono wemveliso yonke. Kulo msebenzi wangoku, iifomyula ezinyangwa yi-UV ezineebhanti ezahlukeneyo ze-monomer-oligomer zalungiswa kwaye zasetyenziswa njengesiseko sesiseko kwinkqubo yokugqiba umthi eneeleya ezininzi. Ngelixa i-topcoat yenzelwe ukunyamezela uninzi lwemithwalo esetyenziswayo, uxinzelelo lwe-elastic kunye neplastiki lunokufikelela kwiileya ezinzulu.
Ngexesha lophando, iipropati zomzimba ezifana nobude obuphakathi becandelo lethiyori, ubushushu bokutshintsha kweglasi kunye noxinano oludibanisayo, lweefilimu ezizimeleyo zezibini ezahlukeneyo ze-monomer-oligomer ziphandwe. Emva koko, uvavanyo lokutsalwa kunye nokumelana nokukrwela lwenziwe ukuze kuqondwe indima yee-basecoats kwimpendulo iyonke yoomatshini beengubo ezininzi. Ubukhulu be-basecoat esetyenzisiweyo bufunyenwe bunempembelelo enkulu ekuchaseni koomatshini kwenkqubo yokugqiba. Akukho nxu lumano ngqo olusekwe phakathi kwe-basecoat njengeefilimu ezizimeleyo kwaye ngaphakathi kweengubo ezininzi, kuthathelwa ingqalelo ubunzima beenkqubo ezinjalo iindlela ezahlukeneyo zokuziphatha zifunyenwe. Inkqubo yokugqiba ekwaziyo ukukhuthaza ukumelana nokukrwela okuhle kunye ne-modulus elungileyo yokutsalwa yafunyanwa kwifomyula ebonisa ukulingana phakathi koxinano lwenethiwekhi kunye nokuqina.
