3M DP270BLACK400ML Epoxy Potting Compound Adhesive
3M Scotch-Weld DP270 is a versatile two-part epoxy potting compound and adhesive. Primarily used for potting, sealing, and encapsulating electronic components, it provides excellent thermal shock resistance, good electrical insulation, and is noncorrosive to copper. It's suitable for applications like potting transformers, coils, chokes, relays, and protecting heat-sensitive components like glass diodes and sensors. Available in bulk containers or the 3M EPX Applicator System for multi-station usage.
