SEP electronic-grade epoxy resin color pastes are solvent-free, offering high fineness and a narrow particle-size distribution. They do not interfere with epoxy curing and provide excellent migration resistance and stable electrical insulation. Ideal for electronic potting, LED encapsulation, PCB conformal coating, power modules, component encapsulation, dry-type transformers, epoxy carbon-fiber composites, and epoxy aramid-fiber ballistic materials.
