Kumapende asekelwe emanzini, ama-emulsion, ama-thickeners, ama-dispersant, ama-solvent, ama-leveling agents anganciphisa ukucindezeleka kobuso bepende, futhi uma lokhu kunciphisa kunganele, ungakhetha i-substrate wetting agent.

Sicela uqaphele ukuthi ukukhetha okuhle kwe-substrate wetting agent kungathuthukisa i-leveling property yopende ophuma emanzini, ngakho-ke ama-substrate wetting agents amaningi ayi-leveling agents.

Izinhlobo zama-substrate wetting agents yilezi: ama-anionic surfactants, ama-nonionic surfactants, ama-polysiloxanes aguquliwe nge-polyether, ama-acetylene diols, njll. Izidingo eziyisisekelo zama-substrate wetting agents ukusebenza kahle kakhulu ekunciphiseni ukucindezeleka kobuso, ukuhambisana okuhle kwesistimu (ikakhulukazi upende olusekelwe emanzini olucwebezelayo), ngokuvamile oluncibilikayo emanzini, ama-bubble aphansi futhi angazinzile, ukuzwela okuphansi emanzini, futhi ngeke kubangele izinkinga zokuvuselela kanye nokulahlekelwa ukunamathela.

Ama-substrate wetting agents asetshenziswa kakhulu yi-ethylene oxide adducts (isibonelo, uhlobo lwe-polyoxyethylene-nonylphenol), uhlobo lwe-polyorganosilicon kanye nohlobo lwe-non-ionic fluorocarbon polymer compounds kanye nezinye izinhlobo, lapho i-fluorocarbon polymer wetting agent yokunciphisa ukucindezeleka kobuso iyona ebaluleke kakhulu.

Umbono ongalungile, othonywe ukukhangisa, ukuthi umphumela wokunciphisa ukucindezeleka kobuso kuphela unqunywa uma kungukusabalala kwengubo engaphansi komhlaba okubaluleke kakhulu, futhi lesi sici sihlobene nokuhambisana kwesistimu kanye nokucindezeleka kobuso okufanele.

Amandla okusabalala kwe-ejenti yokumanzisa anganqunywa ngokulinganisa indawo yokusabalala yevolumu ethile (0.05 ml) yopende ku-substrate efakwe ngaphambili ngemuva kokwengeza ukuhlushwa okunikeziwe kwe-ejenti yokumanzisa kupende. Ama-ejenti okumanzisa.

Ezimweni eziningi, inani lokuqina kobuso obungaguquki alikwazi ukuhambisana nekhono lokumanzisa lopende ngesikhathi sokwakhiwa, ngoba upende usensimini yokucindezeleka ngesikhathi sokwakhiwa, futhi uma ukuqina kobuso obushintshashintshayo kuphansi ngalesi sikhathi, kuzuzisa kakhulu ukumanzisa. Ama-surfactant e-Fluorocarbon anciphisa kakhulu ukuqina kobuso obungaguquki, okungenye yezizathu ezenza ukusetshenziswa kwama-surfactant e-fluorocarbon kuncane kakhulu kunokusetshenziswa kwama-silicone.

Ukukhetha i-solvent efanele kungaba nomphumela omuhle wokumanzisa i-substrate. Ngenxa yokuthi i-solvent iyahambisana nesistimu, ukucindezeleka kobuso obuguqukayo kuphansi.

Ukunaka okukhethekile: uma i-substrate wetting agent ingakhethwanga kahle, izokwakha ungqimba olulodwa lwama-molecule ku-substrate, ngakho-ke ukuhambisana nesistimu yokumboza akusekuhle, okuzothinta ukunamathela.

Izinto eziningana zokumanzisa zingaxutshwa ukuze kuxazululwe ukumanzisa okuyinkimbinkimbi kwe-substrate.
