Beschreibung
Zusammenfassung:	The present technology provides a matting agent for a polyurethane coating composition, the matting agent comprising porous silica particles having a ratio of BET surface area to pore volume (SA: PV) of 160 m2/mL or less. The technology also provides a polyurethane coating composition and a cured coating thereof. These compositions comprise the matting agent, a polyol, a crosslinker, and a catalyst. 本技术提供了一种用于聚氨酯涂层组合物的消光剂，该消光剂包含多孔二氧化硅颗粒，这些多孔二氧化硅颗粒的BET表面积与孔体积的比率(SA∶PV)是160m2/mL或更小。该技术还提供了一种聚氨酯涂层组合物和其固化涂层。这些组合物包含该消光剂、多元醇、交联剂和催化剂。
