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.
Uses
Suitable for capacitor, igniter, transformer, aquarium pump, drive power, sensor and other electronic products insulation waterproof package.
Characteristics
Good insulation performance, good physical properties, excellent surface gloss, good processability and good crack resistance.

Package
Component A: 25kg /barrel
Component B: 5kg /barrel
Storage Conditions
The product should be sealed in its original packaging container and stored in a dry and ventilated place. In an environment of 18-40ºC, the shelf life is 6 months. If the shelf life is exceeded, analysis is required to determine whether it is still valid.
Due to the storage conditions, this product may experience a small amount of precipitation during storage, which is a normal phenomenon. After stirring evenly, it can be used normally.
