There are many kinds of defoaming agents, oily, solvent, silicone, emulsion and solid powder.And defoaming agents have the following properties:

  1, strong defoaming ability, less dosage;

  2. The basic properties of the system will not be affected after the addition of defoaming agent;

  3, small surface tension;

  4, good balance with the surface;

  5. Good dispersity and permeability;

  6, good heat and acid and alkali resistance;

  7, chemical stability, strong oxidation resistance;

  8, gas solubility, good permeability;

  9. Small solubility in foaming solution;

  10, high physiological safety.
