Features of Epoxy Resin Electronic Potting Adhesive:
There are many types of epoxy resin sealing adhesive in the sealing adhesive, with a wide range of applications, especially technical requirements. Therefore, curing can be divided into two types: room-temperature curing and heating curing. Both mechanical sealing and manual sealing can achieve the characteristics of protecting electrical components after solidification, especially with superior waterproof, moisture-proof, and anti-corrosion performance.
Characteristics:
Good insulation performance, physical properties, surface gloss, processability, and crack resistance.
Application:
Suitable for insulation and waterproof packaging of electronic products such as capacitors, igniters, transformers, aquarium pumps, drive power supplies, sensors, etc.

Storage conditions:
The product should be sealed in its original packaging container and stored in a dry and ventilated place. In an environment of 18-40℃, the shelf life is 6 months. If the shelf life is exceeded, the analysis is required to determine whether it is still valid.
Due to 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.
