Electroluminescent paint simply consists of millions of microscopically crystals and each and every single crystal is a lamp on its own.
Thickness electroluminescent layers
It is about the functionality not the thickness of the electroluminescent layers.
The carrier (the paint) is the vehicle to deposit the pigments in a conformal and homogeneous (uniformity) film. (even thickness without “holes” in the film).
For this we may say that the smallest deposit or smallest possible film thickness is sufficient.
This is the key for all layers.
Thickness paint layers on cars
If we talk about the thickness of paint you see on cars, then it’s good to know that this is measured in microns (µm), 1 micron is equivalent to one thousandth of a millimeter (1/1000mm). It consists 3 layers: Primer, Base Color Coat and Clear Coat.
Hardness of the coatings used for the Electroluminescence.
The hardness is depending on the paint that you use for mixing the pigments. Polyurethane finish has the highest hardness.
Perhaps the best to say is to apply it paper Thin – As thin as 0.1mm; typically, between 0.2mm – 0.8mm
Next to the thickness is the use of the correct driver/inverter for the designated field also influential for the overall functionality.
