ADDING METHODS:

Added in the foam solution in advance.
The defoamer can effectively suppress bubbles when it is added in advance.
Continuous trickle-down
In case of a continuous cycle where the defoamer is constantly consumed, using a method of continuous trickle-down the defoamer can effectively eliminate the bubbles.
Spray sprinkling
The use of spraying method is effective when a large number of bubbles are produced in a short time or temporary bubbles generated have to be eliminated. Air gun can also be used to spray the diluted defoamer directly at the foam. Large diameter sprayer is ideal, if the sprayer aperture is too small, the defoamer becomes foggy and cannot effectively eliminate the bubbles.
Smear on the container:
This method is quite effective to control the bubbles generated in certain circumstances. In the foam container paint the defoamer in the shape of a ribbon. The foam will be eliminated if the bubbles reach the surface smeared with the defoamer.

NOTE:

Recommend diluting the defoamer to about 10% of the solution by solvent before using. Add under the condition of a higher dispersion rate and ensure that the defoaming system can be dispersed evenly.
Sediments may occur in the defoamer during storage, but this will not affect the defoaming property. Stir it until the defoamer becomes uniform and then use.
Please do not let the defoamer adhere to the skin / mucus when using. On the case of the defoamer adhesion to the skin / mucus, please wash it immediately with soap, then rinse by adequate water.
