6.Precautions:

1. Components a and B should be sealed and stored. If they are not used up after opening, please seal them again.

2. In the process of glue filling, the mixing container and mixing tools should be kept away from water and moisture.

3. In the process of use, the dripping glue can be cleaned with acetone, ethyl acetate, dichloromethane and other solvents, but the solvent can not be mixed into unused a, B glue and potted glue.

Note: the above performance parameters are the typical data of the product tested at the humidity of 70% and temperature of 23 ℃. It is only for the reference of customers when using, and can not guarantee all the data that can be achieved in a specific environment. Please refer to the measured data when using.

Manual use process:

1. Weigh components a and B according to the weight ratio a: B = 125:100 and put them into a clean mixing container

2. Use a clean mixing tool to stir evenly, and pay attention to scrape off the single component on the bottom and side wall of the container

3. After mixing, vacuumize

4. Curing at room temperature after pouring
