Warm Tips for for PCB Electronic Potting Silicone
1. Sealing package for storage. The mixture should be used up at once to avoid wasting.
2. Silicone belongs to non-dangerous goods, but keep away form mouth and eyes.
3. When it gets stratified after a period of storage, Please mix HY-210# evenly before using,
it does not affect the performance.


Shelf Life and Transportation
1. Twelve(12) months when stored at 25C in original unopened packages.
2. This is a non-dangerous product, it can be transported as general chemicals.
3. Products exceed the storage life should be confirmed normal before using.

Technical Guidelines
1. Pls put part A and B in separate container and stir evenly before mixing the two
parts together.
2. Mixing Ratio part A:part B is 10:1
3. Bubble release if necessary, deaeration the mixture under 0.08 MPa for 3 minutes.
4. HY-215# is cured at room temperature, so pls put it under room temperature after
pouring. It comes to next process when basically cured, and it takes about 24 hours
for completely cured.
