Excellent high and low temperature impact performance 2K epoxy resin adhesive potting for transformers and controllers

SE685 is a solvent-free, black, two-component epoxy potting adhesive that can be cured at room temperature or by heating.

It has low heat emission, low shrinkage and good thermal conductivity when curing.

After curing, it has excellent electrical, mechanical and impact resistance properties, and can be applied to sample parts that need to be fully enclosed and protected, such as transformers, electronic stators, ignition coils, etc.





 

Special features

 

 
1. Excellent capricious and anti-impact resistance.
2. Excellent mechanical properties and electrical properties.
3. Excellent electrical insulation, and thermal stability.
4. Flame retardant UL94 V-0.
5. Excellent high and low-temperature impact performance, usually can withstand 200 hours.
6. Excellent adhesion and anti-cracking properties.
7. Low water absorption, good water, and moisture resistance.





 

Typical Applications

 
1. Applicable to the sample parts that need full enclosed protection, such as transformer, electronic stator, ignition coil, etc.
2. Suitable for motors, automotive electronics, power tools, reactors, instruments, and other encapsulation protection, with excellent adhesion and temperature resistance to most plastic and metal substrates.
