Application method

Given the importance of the mixing ratio of the components and its effect on the quality of the product, we mix the two components A and B together and mix them for 3 minutes with a suitable mixer until they become uniform. Pour the prepared sealant onto the desired surface to spread it evenly on the surface. This work is preferably done in 2 stages.
Usage time: The maximum allowed application time after mixing the components is 30 minutes.

Storage

One year under standard conditions.
