1. Features of power potting silicone rubber

1. It does not shrink during the curing process, and has better waterproof and moisture-proof and anti-aging properties;

2. It is flame-retardant, and the flame-retardant performance reaches UL94-V0.V1 level;

3. The heat transfer medium of components and reduce the working temperature of heating elements;

4. Improve the life and stability of LED lighting products, reduce light decay, and control the temperature rise of the power supply;

5. Temperature resistance, good high temperature aging resistance. After curing, it maintains rubber elasticity and good insulation performance in a wide temperature range (-60~250℃);

6. It has good resistance to alternating heat and cold, and is resistant to corona 

7. The rubber compound can be stored for a long time after being mixed under normal temperature conditions, but it can be cured quickly under heating conditions, which is especially beneficial to the use of automatic production lines.

2. The use process of power potting silicone rubber 

1. Weigh the two components according to the ratio and put them in the mixing tank, stir and mix evenly;

2. Pour the mixed compound into the device to be potted. Generally, vacuum degassing is not required. If high thermal conductivity is required, it is recommended to refill after vacuum degassing. It can be cured at room temperature or by heating. The curing speed of the glue has a great relationship with the curing temperature. It takes a long time to cure in winter. It is recommended to use heating to cure, curing at 80°C for 15-30 minutes, and curing at room temperature generally takes about 6-8 hours.
