3M Scotch-Weld DP270 Clear Potting Epoxy

3M DP270 Clear Potting Epoxy Adhesive Overview

3M DP270 Clear is a two-part, low-viscosity epoxy designed for potting, sealing, and encapsulating delicate electronic components. Its clear formulation offers excellent thermal shock resistance and electrical insulation properties, even in high-humidity environments. Non-corrosive to copper and featuring minimal exotherm, this epoxy is ideal for potting heat-sensitive components like diodes and sensors.

3M DP270 Clear performs well in a variety of industries, including electronics, metalworking, and specialty vehicles. With a 70-minute work life and low shrinkage, it is an excellent choice for potting transformers, coils, relays, and other sensitive equipment.
