HY-9301 Electronic Potting Silicone
The electronic potting silicone is a new type insulation material. Providing no heat production, no corrosion and small shrinkage during cure, the two-component silicone gel is applicable to sealing and potting electric elements. The electronic potting silicone can be cured at room temperature and is easy to use. Also it is able to keep elasticity within a wide temperature range and offers good insulating property. In addition to resistance to chemical mediator, yellowing, weather and ageing, the silicone offers water, moisture, mildew and dust protection.
The electronic potting silicone is suited for electronic parts with water prevention and insulation requirements. Apart from LED and LCD screens, advertising lamps, electronic circuits and PCB substrates, etc., the silicone is used for bonding and sealing power modules and control modules.

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. Leave the uniform mixture for deaeration for three minutes under 0.08MPa.
4. The curing of the electronic potting silicone can be greatly affected by temperature. Under too low temperatures in winter, customers are recommended to heat the mixture appropriately to accelerate vulcanization.
5. Substances such as incompletely cured condensation silicone, amine-cured epoxy resin and solder flux may hinder the curing process or cause the silicone not to be cured. Thus users had better check it before use and clean the surface before applying the silicone if necessary.
Tips
1. The silicone gel should be kept sealed. Use up the well-mixed silicone at one time to avoid waste.
2. Keep the electronic potting silicone away from the mouth and eyes. In case the silicone gets into the mouth or eyes, rinse immediately with plenty of clean water.
3. The product may become layered after being stored for a period of time. Stir it evenly before use, so the silicone 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.
Packaging, Storage and Transportation of the Electronic Potting Silicone
1. The electronic potting silicone is packed in 20Kg/set (A: 10Kg, B: 10Kg).
2. Shelf life of the silicone gel 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.
4. The product can still be used after expiration, if it is rechecked and found suitable for use.
