以下是引用wonder在2005-8-30 16:46:04的发言：

<>就一般的通用树脂，黏度在160~180CPS（brookfield 2#/60)或更低。卡博特的气相二氧化硅！谢谢你们的回信！

可能和气相二氧化硅的品级表面处理有关系~~ 方便的话请告知是那种树脂目前用那种气相二氧化硅

一起等待楼主翔示…………

BYK®-405 Rheology additive for solvent-based systems. The additive is most suitable for coatings based on polyesters, acrylics and alkyds which contain fumed silica. The fumed silica must be at least partially hydrophilic. BYK®-405 facilitates the incorporation of the silica, prevents its separation, increases and stabilizes the thixotropic behavior. It contributes to gloss clarity improvement and humidity resistance of fumed silica containing coatings. Thixotropic resin systems can show additional thixotropy with the post-addition of BYK®-405. Composition  Solution of polyhydroxycarboxylic acid amides
Solvents  Xylene / Alkylbenzenes / Isobutanol 5 / 4 / 1
Dosage (Additive as supplied)  20-40 % upon fumed silica
Typical Physical Data  Non-volatile matter: 52 %
