Electronic Potting Silicone

With low viscosity, the electronic potting silicone is a kind of two-component transparent silicone gel. The silicone is cured at room temperature or by heating. The higher the temperature, the faster it will cure. The electronic potting silicone, without any by-product during cure, can be applied to surfaces of a variety of materials such as PC, PP, ABS, PVC, and metal, etc.

Fully compliant with ROHS requirements, the silicone gel is used for insulation, water prevention and fixing for electric parts and particularly suits applications in precision electronic elements and encapsulation of power modules and circuit boards with high requirement for transparency and recoverability.

Use Instructions on the Electronic Potting Silicone
1. Put component A and component B in separate containers and stir evenly before mixing the two components together.
2. The two components are mixed in the weight ratio of 1:1.
3. The electronic potting silicone can be deaired according to specific needs. Stir the A and B mixture uniformly and then put it into a vacuum container. After 5 minutes' deaeration under 0.08MPa, it will be ready for pouring.
4. Substances such as incompletely cured condensation silicone, amine-cured epoxy resin and solder flux may hinder the curing process or cause the electronic potting silicone not to be cured. Thus users had better check it before use and clean the surface before applying the silicone if necessary.
5. The addition cure electronic potting silicone, before curing and after curing, we should keep the required temperature according to the technical datasheet, and if the silicone is thicker, the curing time will be longer accordingly. The silicone curing speed is influenced by the temperature. It takes a long time for curing in winter when heating is recommended for curing. 20 minutes is required for curing under 80~100℃, and approximately 8 hours at room temperature.

Packaging, Storage and Transportation
1. The electronic potting silicone is packed in 20Kg/set (A: 10Kg, B: 10Kg).
2. Shelf life of the silicone is one year (below 25℃).
3. The goods is NOT subject to the provisions of IMDG code. It is treated as general chemicals for safe transportation.
3. Use it within the warranty period. Our company is not liable for any quality problem due to use after the expiration date or improper storage.

Tips on the Electronic Potting Silicone
1. Keep the electronic potting silicone sealed. Use up the well-mixed silicone at one time to avoid waste.
2. Keep the silicone away from the mouth and eyes. If the silicon gets into the mouth or eyes, rinse immediately with plenty of water or go to see a doctor.
3. After being stored for a period of time, the silicone may become layered. Stir it uniformly before use, so the performance will not be affected.
4. In order to prevent non-curing, the electronic potting silicone should not touch the following substances: organotin compounds and silicone rubber containing organotin; sulfur, sulphide, and sulfur-containing rubber; aminated compounds and amine-containing materials.
