Application areas
Solvent-based, UV-curable systems
Main characteristics
1、It has very good ability to inhibit foam and eliminate microfoam.
2、Since it contains hydrophobic particles, there may be precipitation during storage, which does not affect product quality as long as it is stirred well before use.
3、If used after dilution with solvent, note that the storage period of the diluted solution is limited to 1-2 days.
4、Not applicable to varnish.
5、Can meet the requirements of VOC standard for cigarette packet ink.
6、Reduce the floating surface phenomenon of fumed silica.
Use method
In order to improve the foam inhibition, defoaming and defoaming speed of the system, it should be added to the grinding material.
Recommended dosage
Addition amount (total formula) 0.2-1.0%
Storage stability
Keep in unopened original package for 24 months. Stratification and turbidity may occur at temperatures below 5°C. Heating and thorough mixing before use will not affect product quality. Product beyond the storage period can continue to be used after passing inspection. Before the container is completely empty, it must be tightly closed immediately after use.
Packing
25KG / 180KG.
