Product Description

               High quality High volume resistivity Epoxy potting adhesive

Our products

Transparent Epoxy potting adhesive for Electronic circuit board (PCB)

SE685 


       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.
