以下是引用wonder在2005-8-30 16:46:04的發言：

<>就一般的通用樹脂，黏度在160~180CPS（brookfield 2#/60)或更低。卡博特的氣相二氧化硅！謝謝你們的回信！

可能和氣相二氧化硅的品級表面處理有關系~~ 方便的話請告知是那種樹脂目前用那種氣相二氧化硅

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 %
