Technical Data
3M
Weld™ Epoxy Potting Compound/Adhesive 270 B/A) is a two-part, low viscosity
epoxy resin system designed primarily for potting, sealing, and encapsulation of
many electronic components and is available in clear or black. Scotch-Weld epoxy
potting compound/adhesive DP270 is noncorrosive to copper and offers good
thermal shock resistance and excellent retention of electrical insulation properties
under high humidity conditions.
Scotch-Weld epoxy potting compound/adhesive DP270 has a work life of
approximately 70 minutes, a tack-free time of about 3 hours and is fully cured after
48 hours at 73°F (23°C). This product produces no exotherm in 5-10 gram masses
and a very slight exotherm in larger masses.
Scotch-Weld epoxy potting compound/adhesive DP270 is ideal for the potting and
encapsulation of many heat sensitive or delicate components such as glass diodes
and sensors as well as for transformers, coils, chokes, relays, etc. It is available in
the convenient 3M™ EPX™ Applicator System for multi-station usage and in bulk
containers for larger volume applications.
Available in bulk containers as Scotch-Weld epoxy potting compound/adhesive
270 B/A.
