Features
Defoamer HY8201 is silicone defoamer with good function in different industrial application and is superior in foam inhibiting and defoaming in coating. It is a type of defoamer with good durability
Applications
It can be applied in chemcical industry such as screen printing ink, UV ink, and epoxy floor coating, etc. It can be applied in unsaturated polyester system as well as in PU potting adhesive
Using method
Dosage: 0.01 -1.00% of the total paint formulations. When it is added before grinding or stirring, it can the best effect on form inhibiting. It can be also added after the process with even stirring. It is necessary to make an application test to test the compatibility. it has high active content,it can be dissolved to 10% with aromatic solvent before added into the formulation. And it is also suggested to be used up immediately after dilution to avoid the deposit of hydrophobic particles. And it is thixotropic and its viscosity is apt to increase under the low temperature or after long time laying. This is a normal phenomenon and is suggested to stir evenly before using.
