Defoamer is an additive that can reduce the surface tension of water, solution, suspension and other substances, prevent the formation of foam, or reduce or even eliminate the original foam . Its principle of action is to destabilize the bubble wall and rupture, thereby releasing the trapped gas.
The defoamer has the following characteristics:
1. Strong defoaming ability, less dosage;
2. Adding to the foaming system does not affect the basic properties of the system, that is, it does not react with the defoaming system;
3. Chemically stable, strong oxidation resistance;
4. The solubility in foaming solution is small.
Categorized Applications
Defoamers can be divided into organic silicon, polyether, polyether modified polysiloxane, etc. according to their chemical properties; Foaming type defoamer, defoaming type defoamer.
Defoamers are widely used in coatings, adhesives, detergents, cutting fluids, pesticides, pharmaceuticals and other industries.
