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. 5108 is available in one-part pre-mixed and frozen syringes and two-part room temperature stable kits.
