Electronic-Grade Epoxy Color Pastes
SEP series is an electronic-grade epoxy colorant system containing no organic solvents, featuring high fineness with narrow particle size distribution, no interference with epoxy curing, migration resistance and stable insulation. Designed 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. Delivers long-lasting precise color and compliance for precision electronics manufacturing.
11 Grades Available
