FINE-SIL517 silica particles can enhance the defoaming effect of defoamer. In defoamer products, the defoaming effect needs to be strengthened by silica particles. Silica particles are carried by silicone oil to the air water interface of the foam and enter the bubble liquid film. Because of its hydrophobicity, the contact angle with the surfactant foaming liquid drops is greater than 90 °, which forces the foaming liquid to drain away from the surface of solid hydrophobic particles, causing rapid local drainage of foam, resulting in fracture. In this way, due to the synergistic effect, the two components have a good defoaming effect. It is widely used in defoamers.
