Description
Permabond MT382 is a two-part, modified epoxy adhesive engineered for high-performance bonding, sealing, and potting applications. It forms strong, flexible bonds on a wide variety of materials—including nylon, ABS, polycarbonate, metals, and composites—and cures at room temperature. The product’s self-leveling nature and variable mix ratios make it ideal for both manual and automated dispensing in electronic potting, encapsulation, and industrial assembly.
