Application areas
溶剂型紫外线固化系统
主要特点
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、不适用于清漆。
5、Can meet the requirements of VOC standard for cigarette packet ink.
6、Reduce the floating surface phenomenon of fumed silica.
使用方法
In order to improve the foam inhibition, defoaming and defoaming speed of the system, it should be added to the grinding material.
建议用量
添加量（配方总量） 0.2-1.0%
