3.Let the components sit,out of bubble by themselves,heat curing (In 120?, needs about 2-5mins,depending on the thickness of the adhesive), or curing in the room temperature after the bubble disappeared,need about 6-10hours.

4.About potting equipment please contact our Marketing Department

Note:

1.It can improve the performance of the hardened by vacuum defoaming for mixed component.

2.After use, please seal the package.

3.The curing speed will be slow in the low temperature, suggest workshop in constant temperature.The temperature is too low will lead curing speed Pianman, the proposed workshop thermostat

4.Once SI2721 contact with sulfur, amine, tin material would be difficult to sclerosis.
