Two conventional adding methods of silicone defoamer



1. Add before foaming


This method inhibits foam production by beforehand adding defoamer to the system where foam is likely to occur. For closed containers and devices, defoamer can effectively eliminate foam.




2. Add continuous drops


When the foaming liquid is either circulating or flowing, the circulating flow of the foaming liquid will consume the defoamer. In this case, the continuous drip of the defoamer can effectively eliminate the foam, and the addition amount can be effectively controlled if supplemented by the dosing pump to achieve the most economical use of the defoamer.


Precautions before adding
1, before use need to fully stir the emulsion. Because the uneven emulsion will easily produce stratification, affecting the use of defoamer effect.






2, try to use thickener to dilute. Silicone defoamer can be diluted when used, but at the same time the stability of the defoamer will also be sharply reduced, such as stratification, so it is recommended to use thickener as much as possible when diluting, if the water is diluted, then please add water to the defoamer and slowly stir, and use up the same day.






3. Prevent frost. Silicone defoamer is sensitive to frost and high temperature and is easily destroyed. If the defoamer has been frozen, it must be carefully frosted and tested before use
