5108 Epoxy

Self-leveling, withstands high humidity environments

5108 is a black, electrically isolating epoxy adhesive specifically designed for potting and sealing electronic components. 5108 is a self-leveling material that exhibits low shrinkage once cured and can withstand high temperatures and high humidity or wet environments. This material is also environmentally friendly and considered non‐hazardous per D.O.T. regulations. 5108 is available in one-part pre-mixed and frozen syringes and two-part room temperature stable kits.
