What is a Dielectric Coating?
A dielectric coating is a thin layer of material that is applied onto the surface of an object to improve its electrical insulation properties. They are commonly used in electronic devices, EV batteries, and e-motors to prevent electrical current from flowing across or through the surface of a component or device.
How Does Dielectric Coating Work?
When dielectric coating materials are applied to a surface, they create a barrier that prevents electrical charges from passing through or across the surface. This barrier is created by the properties of the dielectric material used in the coating.
JMC 700K Dielectric Epoxy Coating
Applications: Battery Cooling Plate, Battery Box, Motor Magnets
JMC 700k is a matte black heat-cure, epoxy-based coating provides excellent electrical insulation and protects against corrosion and heat. JMC-700k can be spray or dip applied to cooling plates, battery boxes or permanent magnets for e-motors.
Sipiol Ultra-Violet (UV) Cure Dielectric Coating
Applications: Battery Cells, Battery Boxes, Battery Cooling Plates
Sipiol UV is a UV-cured, VOC-Free, 100% solids, dielectric coating that cures in seconds that has superior adhesion to metals and plastics. It’s electrically insulative and can eliminate PET tapes and powder coating allowing you to decrease the risk of a shock-induced delamination of cells from cooling plates, replace traditional adhesive tapes and separators allowing for more cells to be placed in the same space and reduce overall thermal impedance.
