Product Description

There are many varieties of epoxy resin potting sealant in potting sealant, and the scope of application is wide, especially in terms of technical requirements. Therefore, in terms of curing, it can be divided into two types: room temperature curing and heating curing. Whether it is mechanical potting or artificial potting, it can achieve the characteristics of protecting electrical parts after curing, especially the superior waterproof, moisture-proof, and corrosion resistance.
