Silicone Defoamer HY8300

Similar to KS66

Defoamer HY8300 is a type of polysiloxane containing the hydrophobic particles, and it has excellent defoaming ability. After the defoamer penetrates into the elastic film of foam, it will be distributed evenly on the film surface. With the decrease of surface tension, the thin layer will rapture. Or a mono-molecular film will be formed and it will help the thin layer rapture with lower surface tension. In addition, the hydrophobic particles in defoamer HY8300 will reach the surface of thin layer, and will absorb the surfactant, thus the thin layer is easy to be broken with less surfactant

  2. Defoamer HY8300 can be applied in resin system such as screen printing inks,  PCB inks,phenol-formaldehyde resin, expoxy resin system adhesive
  3. Defoamer HY8300 can be applied in Fermentation industry
  4. Defoamer HY8300 can be applied in petroleum process, such as vacuum distillation monomers, gas scrubbing,ethylene glycol

Using method of Defoamer HY8300

Dosage: 0.05 -1.00%. The examination of the compatibility need to be tested if it is used in the transparent system.Because defoamer HY8300 has high active content,it can be dissolved to 10% with aromatic solvent before adding it to the formulation. The hydrophobic particles in defoamer is easy to deposit,it is suggested to use immediately after diluted.
