Se685 Two Parts Epoxy Potting Compound for LED Light Strip, Automotive Electronic Module, Solar Module Junction Box Potting

Product Description

Our products

SE685 is a solvent-free, black,

Two-component epoxy potting resin adhesive

It can be cured at room temperature or by heating.
After curing, it has excellent electrical, mechanical, and impact resistance properties. It can be applied to sample parts that must be fully enclosed and protected, such as transformers, electronic stators, ignition coils, etc.

Direction of Applications

Manual mixing process (230g mixing volume)

1. Preheating: AB component in low temperature, the viscosity will become high, it is recommended to preheat to 20 ~ 25 ºC, easy to use.
2. Mixing: proportionally weighing A, and B components, mixing vertical stirring rod, clockwise (or counterclockwise) in the same direction and rapid mixing for 3 minutes, 110-120 Circle/min, pay attention to the bottom of the container, the edge should also be stirred evenly, otherwise there will be a local phenomenon of non-curing.
3. Pouring: pour the mixture into the device (Note: 2-3 minutes to pour the glue on the product), if the device has a complex structure and large volume, it should be poured in stages.
