Defoamers
Defoamers contain organomodified polysiloxanes which are characterized by their degree of incompatibility. For each system that has to be defoamed, 4 parameters must be considered with respect to relative importance and the production process. This way, the appropriate defoamer will be selected:
Eficiency
Long term stability
Surface defect trends
Incorporation
