What are the advantages and disadvantages of epoxy resin electronic potting glue?

Advantages of epoxy resin electronic potting glue:

Epoxy resin potting glue is mostly hard, and there are also a few modified epoxy resins that are slightly softer. The biggest advantage of this material is that it has good adhesion to the material and good insulation, and the cured product has good acid and alkali resistance. Epoxy resin potting glue generally has a temperature resistance of 100°C. The material can be used as a transparent material with good light transmittance.

Disadvantages of epoxy resin electronic potting glue:

1. It has weak resistance to cold and heat changes. It is prone to cracks after being exposed to cold and heat shocks, causing water vapor to seep into electronic components from the cracks.

2. Poor moisture-proof ability; after curing, the colloid hardness is high and brittle, and high mechanical stress can easily strain electronic components;

3. Once the epoxy resin potting glue is potted and solidified, it cannot be opened due to its high hardness. Therefore, the product is a "lifetime" product and components cannot be replaced;

4. Transparent epoxy resin materials generally have poor weather resistance and are prone to yellowing under light or high temperature conditions.

Application scope of epoxy resin electronic potting glue:

Generally used for potting of non-precision electronic devices such as LEDs, transformers, regulators, industrial electronics, relays, controllers, and power modules.
