German technical background VOK-Defom 6800 Defoamer For floor coating and screen printing ink replaces Elementis Defom 6800

German technical background Volcker VOK ?- Defom 6800 defoamer

Excellent defoaming and antifoaming performance has significant defoaming and antifoaming effects on high viscosity, high film thickness and solvent-free systems.

Overview: VOK ?- Defom 6800 is a foam inhibitor and defoamer for high solid content, high film thickness epoxy floor coating and screen ink

nature

(This data is only for test reference. If you need detailed product inspection technical indicators, please contact our company.)

Composition: polysiloxane compound containing hydrophobic particles

Appearance: translucent liquid

Nonvolatile: ≥ 99%

Specific gravity: 0.96-1.00

Refractive index: 1.399-1.409 (25 ℃)

Characteristics and use

Excellent foam inhibitor and defoamer. It has a good effect of inhibiting and eliminating bubbles generated in the manufacture and construction of high solid and solvent-free epoxy coatings

It has a good inhibiting effect on the bubbles of epoxy floor coatings with high viscosity and high film thickness, especially solvent-free high film thickness

application area 

Screen ink

Ultraviolet inks 

Epoxy floor coating

Addition amount and use method

Add 0.01-1.0% to the full amount

Before grinding or mixing, add foam inhibitor with good effect, and then add it to eliminate foam. However, it must be fully mixed evenly

To get VOK ?- Defem 6800 has better distribution and effect. It is recommended to grind with abrasive in colored coatings

Because VOK ?- Defem 6800 has high active content, which can be diluted to 10% with aromatic solvent before adding. Because hydrophobic particles are easy to precipitate, it is recommended to use it immediately after dilution

This product has thixotropy, and its viscosity tends to rise when it is kept for a long time or at low temperature. It is a normal phenomenon. It is recommended to stir it evenly before operation to facilitate use

Storage

The storage environment is 0-40 ℃

Place in a cool and ventilated place, keep the container tight and away from heat and fire sources
