slot die coating

Compact, affordable, and pecise slot die coating equipment for scalable thin film deposition. With customizable slot-die head, upfront pricing and free shipping.

The dry coating layer thickness was adjusted to 1.5 for all coatings using the slot-die, thus leading to the wet layer thicknesses listed in for all parameter sets.

High-precision slot die coating equipment Slot-die coating is a coating technique in which a solution is delivered onto a substrate via a narrow slot positioned close to the surface. The slot-die has a high aspect ratio outlet controlling the final delivery of the coating liquid onto the substrate. This results in the continuous production of a wide layer of coated material on the substrate, with adjustable width depending on the dimensions of the slot-die outlet. By closely controlling the rate of solution deposition and the relative speed of the substrate, slot-die coating affords thin material coatings with easily controllable thicknesses in the range of 10 nanometers to hundreds of micrometers after evaporation of the precursor solvent.
