Important – Mix CW 177 Before Use

CW 177 contains mineral fillers which may settle during storage. Part A should be thoroughly homogenised before use, particularly when only a portion of the container is being measured.

After homogenising Part A, accurately measure the required amount of CW 177 and HY 177 and mix thoroughly, taking care to minimise air entrapment.
