Product Details
應用領域
常溫固化塑料體(tǐ)系
特性和優點
BYK-220 SN 能改善所有傳統填料的分(fēn)散,例如碳酸鈣和氫氧化鋁。它能降低填充樹(shù)脂的粘度,從而提高填料的添加量。在大(dà)多數情況下(xià),儲存過程和加工(gōng)過程中(zhōng)填料的沉降可大(dà)幅減少。BYK-220 SN适用于膠衣中(zhōng)顔料分(fēn)散的穩定。該助劑還含有少量聚矽氧烷共聚物(wù),以改善浮色發花現象。這一(yī)成分(fēn)可防止貝納德漩渦的形成,并增進表面滑爽和流平。
推薦用途
該助劑特别推薦用于不飽和聚酯樹(shù)脂、膠衣、丙烯酸、聚氨酯和環氧樹(shù)脂,在所有應用領域都表現出了最高效的性能。
建議用量
0.5-1.5%助劑(購入形式)基于填料。
以上推薦添加量供參考,最佳添加量需經過一(yī)系列試驗确定。
加入方法及加工(gōng)指導
爲了獲得最佳性能,助劑應當在添加固體(tǐ)物(wù)料之前加入。
塗料工(gōng)業
特性和優點
該助劑可提供一(yī)種所希望的、顔料的受控絮凝,這一(yī)體(tǐ)系在各個顔料顆粒之間架起橋梁,從而形成三維網絡結構。顔料的這種受控絮凝有效防止了浮色發花以及沉降和流挂。
BYK-220 SN适用于工(gōng)業塗料和建築塗料中(zhōng)顔料的分(fēn)散穩定。它能提高光澤,防止發花,以及降低研磨料的粘度。該助劑還含有少量聚矽氧烷共聚物(wù),以改善浮色發花現象。這一(yī)成分(fēn)可防止貝納德漩渦的形成,增進表面滑爽和流平,及消光粉和鋁粉顔料的定向。在大(dà)多數情況下(xià)無需另外(wài)添加常規配方中(zhōng)所必須使用的有機矽助劑。
建議用量
助劑用量(購入形式)基于:
無機顔料: 3-10 %
钛白(bái)粉: 1-3 %
有機顔料: 8-16 %
以上推薦添加量供參考,最佳添加量需經過一(yī)系列試驗确定。
加入方法及加工(gōng)指導
爲了獲得最佳性能,助劑必須先加入研磨料中(zhōng),然後再投入顔料。
