Usually two-component potting adhesive is more suitable for the overall parts of the potting, potting can strengthen the performance of electronic products, the use safer. When bonding electronic components, a one-component electronic potting adhesive is usually used, which is easy to operate and suitable for both manual application and automatic assembly line application.
To judge the quality of the potting adhesive, several aspects need to be considered.
1, you can test the electrical performance of the cured potting adhesive, only the leakage resistance, corona resistance potting adhesive are good quality. Such potting glue has insulation performance, used in electrical appliances can strengthen the insulation performance, not easy to occur leakage accidents.
2, has been cured after the potting adhesive can be tested whether it has the performance of blocking ultraviolet light, with this performance of the potting adhesive to prove good sealing performance, moisture, moisture, and other substances have good resistance.
