Precision low-pressure application for sharp indoor floor lines, reduced airborne particles and consistent film thickness.
Discuss a validation trial
The Sharpliner applies indoor floor marking lines using slot die coating technology - a precision coating method used for decades in battery manufacturing, pharmaceutical production and industrial surface finishing.
Instead of atomising material at high pressure through a spray tip, the system meters material through a precision shim chamber and deposits it as a controlled coating curtain from just 5-10 mm above the surface.
The result is a specialist application method for sharp-edged indoor lines, difficult-to-spray coatings and environments where airborne contamination, masking tape and film thickness variability create practical limitations.
Slot die technology for indoor floor marking
Max. 3.0 bar material / 1.0-1.5 bar atomising air
Sharp line edges without masking tape
For food, pharmaceutical, clean-area and active warehouse facilities where reduced airborne particles matter.
Line edges are defined by die lip geometry, eliminating the masking step for straight-line work.
Low-shear, pre-metered delivery for high-viscosity, fast-curing or shear-sensitive formulations.
Airless spray is proven and efficient, but high-pressure atomisation can create overspray, variable line edges and operator-dependent film thickness.
A low-pressure, premetered coating curtain that delivers sharp, repeatable straight lines with reduced airborne particle generation at recommended parameters.
