    Operation Process

    1. Weigh hardener CPU-55-B first and pour it into a mixing container to lubricate the sides of the container. 
    2. Weigh CPU-55-A then pour it into the same mixing containerand mix thoroughly for 1-2 min with stir speed 100-200 rpm. (Please do not stir with high speed.) 
    3. Place the container into vacuum machine to exhaust the air twice for 1-2 min each time. (This step could be neglected if one does not have a vacuum machine.)  
    4. Pour the mixed material into the molds (The molds should be applied to the release agent in advance.) or direct use.
