Application method

1.Before mixing A and B, part A should be fully stired, and part B should be shaked in its own container.

2.Mixing Weight ratio of A and B is A: B = 10:1, if operational conditions are needed to be changed, the mix ratio should be distinguished from 10:1, and it is advised to do some simple experiments before application. The more dosage of part B, the shorter time of the curing and operation.

3. If the potting depth is deep, bubbles may appear in the inner parts or on the surface of the glue, so it’s better to put both A and B into a vacuum vessel, and mix them in the condition of -0.06MPa in 5 to 10 minutes.


The product should be stored in a shady, dry place with the temperature of 0°C-40°C, freezing should be avoided.

The expiration date is 9 months.

Avoid from acid, alkali chemical materials and other impurities.

Handle as non-hazardous substance.

Notice: Above-mentioned technology is based on the situation that we master. For actual application, please refer to your actual requirement.
