PEG-12 Dimethicone Manufacturers introduces the precautions for the use of silicone defoamers:
1. Oil-in-water emulsions can be arbitrarily diluted, but at the same time the stability of the emulsion will drop sharply, such as stratification.
2. When diluting, add water to the defoamer and stir slowly.
3. Since the emulsion has the best stability at the original concentration, the diluted emulsion must be used up within a short period of time.
4. Emulsion is sensitive to frost and temperature higher than 40°C and is easily damaged.
5. Prevent frost! Emulsion that has been frozen can be carefully defrosted, but it must be tested before further use.
6. Long-term strong shaking or strong shearing (such as using mechanical pumps, homogenizers, etc.) or stirring will destroy the stability of the emulsion.
7. Increasing the viscosity of the emulsion or adding thickeners can improve the stability of the emulsion.
Through the above introduction, 1,3,5,7-Tetramethylcyclotetrasiloxane Manufacturers hopes that you can simply refer to the content of this article in future use.
