Component:Polysiloxane containing the Hydrophobic particles
||Half transparent to cloudy liquid
Silicone Defoamer HY-8200 has excellent foam inhibiting ability and is excellent in defoaming in the production of paint or ink. It can be applied to both solvent and non-solvent system and is suitable for high viscosity system
Expoxy floor coatings，screen printing inks, UV ink, unsaturated polyester systems, etc.
Dosage: 0.01 -1.00% in the coatings formulations. It can get the best foam inhibiting result if adding before stiring or grinding.It can be also added after the process，but stirring to even is a must. The compatibility test is necessarry when using in transparent system. 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.This product has thixotropy,the viscosity is easy to increase after long time laying or under the low temperatures,which is a normal phenomenon. It is suggested to stir evenly before operations .
