使用byk-405。

The improved rheological effciency can be distinctly seen in clear varnishes as the incorporation of fumed silica

改进的流变性可以清楚地看到清漆作为气相二氧化硅掺入

The additive reduces or prevents the separation of fumed silica in the paint.

添加剂减少或防止涂料中二氧化硅的分离。

BYK-405 is best suited for solvent-borne systems based on polyesters, acrylics and alkyds that contain fumed
