3M Scotch-Weld DP270 Low-Viscosity Epoxy Potting Compound Electronic Components

Basic Properties​

3M Scotch-Weld DP270 is a two-part low-viscosity epoxy potting compound/adhesive available in Clear and Black variants. It features a 1:1 mix ratio by volume, 60-70 minute worklife at 23°C, designed for potting, sealing, and encapsulation of electronic components with negligible exotherm and non-corrosive to copper.

Product Description​

DP270 is ideal for protecting heat-sensitive components (e.g., glass diodes, sensors) and precision electronics (transformers, relays). It maintains excellent electrical insulation under high humidity (volume resistivity 4.1×10¹⁴ ohm-cm), certified UL 94 HB (File E61941), with full cure in 48 hours at 23°C.
