First, before the use of the need to fully stir the emulsion. Because the emulsion is not uniform can easily produce stratification, affect the use of defoaming agent.Second, try to use thickening agent to dilute. Silicone defoaming agent can be diluted when used, but the stability of defoaming agent will decrease sharply when diluted. For example, stratification occurs. Therefore, it is recommended to use thickener for thinning when diluted.Third, prevent frost. Silicone defoaming agent is sensitive to frost and high temperature and easy to be damaged. If frostproof, be sure to remove frost carefully and test before using.Fourth, pay attention to the storage of silicone defoamer. Long periods of strong oscillation or strong shear (e.g., mechanical pumps, homogenizers, etc.) or agitation can damage the stability of the defoamer, so pay attention to the storage of silicone defoamer.
