Slot-DieCoatingOverview
ReliableandSimple-Slot-diecoatingisoneofthemostreliabletechniquesforfabricatingthinwetfilms,andiscapableofproducingcoatingswithvariationslowerthan5%acrossmanymeters.Thecontrolofthicknessissimplygovernedbythesolutionflowrateandsubstratespeed,whilethepresenceofcoatingdefectscanbeeliminatedbyvaryingseveralgeometricparameters(whichdonotalterthecoatingthickness).

ControllingFilmThickness-Asslot-diecoatingisapre-meteredcoatingtechnique,thethicknessofthedepositedwetfilmonlydependsonthesolutionflowrate,thespeedofthesubstrate,andthewidthofcoating.Whenthesolutionconcentrationandmaterialdensityistakenintoaccountitispossibletodeterminethedryfilmthickness,thisisgivenintheequationbelow.
