Ngaphambi kokuqonda abagqugquzeli bokunamathela, kumelwe siqale siqonde ukuthi kuyini ukunamathela.

Ukunamathela: Isenzakalo sokunamathela phakathi kwendawo eqinile kanye nokuhlangana kwento ethile ngokusebenzisa amandla ama-molecule. Ifilimu yokumboza kanye ne-substrate kungahlanganiswa ndawonye ngokubopha ngomshini, ukumuncwa ngokomzimba, ukubopha kwe-hydrogen kanye nokubopha kwamakhemikhali, ukusabalala okuhambisanayo kanye neminye imiphumela. Ukunamathela okudalwe yile miphumela kunquma ukunamathela phakathi kwefilimu yopende kanye ne-substrate. Lokhu kunamathela kufanele kube yisamba samandla ahlukahlukene okubopha (amandla okunamathela) phakathi kwefilimu yopende kanye ne-substrate.
Kuyisici esiyinhloko sezingubo zokugqoka ukudlala indima yokuvikela, ukuhlobisa kanye nemisebenzi ekhethekile. Ngisho noma ingubo ngokwayo inezakhiwo ezinhle kakhulu zomzimba nezamakhemikhali, ngeke ibe nenani elikhulu eliwusizo uma ingakwazi ukubopha ngokuqinile nomphezulu we-substrate noma i-base coat. Lokhu kubonisa ukubaluleka kokunamathela ekusebenzeni kwezingubo zokugqoka.
Uma ukunamathela kwefilimu yopende kukubi, izinyathelo ezinjengokugaya i-substrate, ukunciphisa i-viscosity yokwakha i-coating, ukwandisa izinga lokushisa lokwakha, kanye nokomisa kungathathwa ukuze kuthuthukiswe amandla okubopha ngomshini kanye nomphumela wokusabalalisa, ngaleyo ndlela kuthuthukiswe ukunamathela.

Ngokuvamile isikhuthazi sokunamathela siyinto ethuthukisa ukubopha phakathi kwezindawo ezimbili, okwenza ukubopha kuqine futhi kuhlale isikhathi eside.
Ukwengeza abagqugquzeli bokunamathela ohlelweni lokumboza nakho kungenye yezindlela eziphumelela kakhulu zokuthuthukisa ukunamathela.

Abagqugquzeli bokunamathela banezindlela ezine zesenzo:
Ukubopha ngamakhemikhali kokubili ifilimu yopende kanye ne-substrate;
Ukunamathela kwamakhemikhali kwefilimu yopende kanye nokugoqa ngokomzimba kwesisekelo;
Ukugoqa okungokoqobo kwefilimu yopende kanye nokubopha kwamakhemikhali kwesisekelo;
Ukugoqa okungokoqobo kokubili ifilimu yopende kanye nesisekelo.

Ukuhlukaniswa kwabagqugquzeli bokunamathela okuvamile
1. Abagqugquzeli bokunamathela kwe-polymer yemvelo. Abagqugquzeli bokunamathela abanjalo bavame ukuqukatha amaqembu okunamathela kwe-substrate njenge-hydroxyl, i-carboxyl, i-phosphate, noma izakhiwo ze-polymer ze-long-chain, ezithuthukisa ukuguquguquka kwefilimu yopende futhi zithuthukise ukunamathela kwefilimu yopende ku-substrate.
2. Abagqugquzeli bokunamathela kwe-ejenti yokuhlanganisa i-silane. Ngemva kokufakwa kwengubo enenani elincane le-ejenti yokuhlanganisa i-silane, i-silane iyahamba iye endaweni ephakathi kwengubo kanye ne-substrate. Ngalesi sikhathi, lapho ihlangana nomswakama ebusweni be-substrate, ingafakwa i-hydrolyzed ukuze yakhe amaqembu e-silanol, bese yakha izibopho ze-hydrogen namaqembu e-hydroxyl ebusweni be-substrate noma ihlanganiswe ibe yizibopho ze-covalent ze-Si-OM (M imele ubuso be-substrate); ngesikhathi esifanayo, amaqembu e-silanol phakathi kwama-molecule e-silane ahlangana ukuze akhe ifilimu emboza isakhiwo senethiwekhi.

Izici okufanele uzicabangele lapho ukhetha abagqugquzeli bokunamathela
Ukuhambisana kwesistimu;
Ukuqina kwesitoreji;
Ithonya ezimpahleni eziyisisekelo zomzimba nezamakhemikhali zezingubo zokumboza;
Ukwelashwa komhlaba we-substrates;
Ukuhlanganisa nezinye izinto zokusetshenziswa ukuze kuthuthukiswe ukwakheka kokumboza.
