Electronic Potting Silicone

Electronic Potting Silicone

The two-component electronic potting silicone with low viscosity allows fast cure at room temperature. The condensation type silicone sealant can be applied to the surfaces of PC, PP, ABS, PVC, metal, and other materials, providing good adhesion property. Fully compliant with ROHS requirements, the electronic potting silicone is typically used for encapsulation of electric modules and outdoor LED display screens, as well as insulation, water prevention and fixing for electric components.

Use Instructions on the Electronic Potting Silicone
1. Before mixing, first stir component A evenly till the sediment is uniform, and shake component B well.
2. A and B are mixed in the weight ratio of 10:1.
3. The electronic potting silicone can be deaired according to specific needs. Stir the A and B mixture uniformly before putting it into a vacuum container. After 3 minutes' deaeration under 0.08MPa, it will be ready for pouring.
4. After pouring, the silicone is kept at room temperature for cure. It goes to the next process until it is largely cured. 24 hours is required for complete cure. Ambient temperature and humidity have considerable impact on the product's curing.

Note: The above performance data are based on 25℃ temperature, 55% relative humidity and one day after curing. The data are subjected to change under different test conditions and without notice due to product improvement.

1. Keep the electronic potting silicone sealed. Use up the well-mixed silicone at one time to avoid waste.
2. Keep the product 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.

Packaging, Storage and Transportation of the Electronic Potting Silicone
1. The HY-215 electronic potting silicone is packaged in 22kg / set (A: 20kg, B: 2kg).
2. The shelf life of the silicone is three months (below 25℃). Our company is not liable for any damage or problem due to use after expiration.
3. The goods is NOT subject to the provisions of IMDG code. It is treated as general chemicals for safe transportation.
