 <br />
Warm Tips for for PCB Electronic Potting Silicone<br />
 1. Sealing pakage for storage. The mixture should be used up at once to avoid wasting.<br />
 2. Silicone belongs to non-dangerous goods, but keep away form mouth and eyes.<br />
 3. When it gets stratified after a period of storage, Please mix HY-210# evenly before using,<br />
      it does not affect the performance.<br />
<br />
Shelf Life and Transportation<br />
1. Twelve(12) months when stored at 25C in original unopened packages.<br />
2. This is a non-dangerous product, it can be transported as general chemicals.<br />
3. Products exceed the storage life should be confirmed normal before using.<br />
 <br />
Technical Guidelines<br />
1. Pls put part A and B in separate container and stir evenly before mixing the two<br />
   parts together.<br />
2. Mixing Ratio part A:part B is 10:1<br />
3. Bubble release if necessary, deaeration the mixture under 0.08 MPa for 3 minutes.<br />
4. HY-215# is cured at roon temperature, so pls put it under room temperature after<br />
   pouring. It comes to next process when basically cured, and it takes about 24 hours<br />
   for completely cured.<br />
