Characteristics

1. Hardness: 75 Shore A
2. Size stable & hardening at room temperature
3. Good resistance for the alkalinity and acid

Processing

1. Stir CPU-66-A about 1 – 2 minutes for ready-use first (material will slightly precipitate).

2. Weigh CPU-66-B and then pour it into mixing container and let it lubricate the sides of the mixing
    container first.

3. Weigh the appropriate amount of CPU-66-A and then pour it into the same container, mix thoroughly by

    agitator at 100 – 200 rpm for at least 1 – 2 minutes making sure that you scrape       the sides and bottom
    of the mixing container several times. Please do not agitate with high speed.

4. Put the mixture into the vacuum to degas about 1 – 2 minutes and then exhaust about 2 times. Then, you

    can use the mixture according to your own purposes.   

Package

CPU-66-A

Note

1. The container of CPU-66-B must be sealed tightly after the use; otherwise, it will become stiff and

    cannot be used anymore.

2. The pot life is short, so please pay the most careful attention while using it. 

3. CPU-66-A will be slightly precipitated, so please stir it completely and evenly.
