A　mathematical　study　of　an　Oldroyd　4-constant　fluid　for　a　blade　coating　process　is　studied　in　this　paper.　The　results　for　plane　as　well　as　exponential　coaters　are　analyzed.　Suitable　dimensionless　variables　are　used　to　convert　the　model　governing　equations　into　dimensionless　form.　Lubrication　approximation　theory　is　applied　to　simplify　the　dimensionless　form　of　governing　partial　differential　equations.　The　well-known　numerical　technique　known　as　the　shooting　method　is　used　to　solve　the　non-linear　boundary　value　problem.　Influence　of　the　involved　theological　parameters　on　the　blade　coating　process　is　analyzed.　From　an　engineering　point　of　view,　load　on　the　blade　and　pressure　are　important　outcomes　of　the　present　study　as　they　ensure　the　thickness　and　quality　of　coating　and　enhance　the　life　of　the　substrate.　The　effects　of　material　parameters　on　load,　thickness,　velocity,　pressure　and　pressure　gradient　are　discussed.　Obtained　results　for　velocity,　pressure　gradient　and　pressure　distribution　are　shown　graphically,　whereas　load　and　thickness　are　expressed　in　a　tabulated　form.
