We had several questions for addressing the conductive paints & Busbars.
What is a bus-bar? a system of electrical conductors in a generating or receiving station on which power is concentrated for distribution.
As you know, litcoatings consist of different paint or coating layers working together.
From principle – the general essentials allow to use one of the Conductive paints below: (just to name a few)
Copper Conductive Paint
Silver Conductive Coating
Silver Coated Copper Conductive Coating
Nickel Conductive Coating
Optional is to use as bus-bar one of the above paints: copper, silver or nickel paints.
Conductive paints or varnish are mixed with metal particles that can transmit an electrical current and can be used for artistically projects.
The silver coated copper paints are perfect to use as your first conductive layer and to use as busbar or grid for the above transparent conductive layer.
“bus-bar” is just a functional name and perhaps “grid” or “raster” would be more appropriate in line with your design.
The above conductive layer is commonly used in combination with high- conductive busbar-grids for larger objects.
Try it out on small samples until you have it right. Also make sure that the layers do not short circuit.
The bus-bar “grid” or “raster” can have any other form according your own design.
Recommend bus-bar “grid” or “raster” surface area is 1/3 or 33%
LitCoat functionality is all about capacitive reactance within the capacitor, as that is actually what lit-coatings are. High frequent changing electromagnetic fields exiting the electroluminescence.
