Product Information Sheet
Product Label


DEFOAMER WTC-20 is most effective in aqueous systems. Depending on the application, concentrations of 0.0025% to 0.12% may be needed to achieve a suitable defoaming action. In many cases, results can be obtained by using even lower dilutions.

For best results, DEFOAMER WTC-20 should be added at a point in the system prior to the foam formation. It should be thoroughly mixed to ensure the most economical performance.
