吸墨涂料
气相金属氧化物是非常高效的预涂覆添加剂，可在各种基材上用于墨水吸附。
我们提供广泛的 CAB-O-SIL® 气相二氧化硅、SpectrAl® 气相氧化铝和 CAB-O-SPERSE® 水分散剂，可用于油墨接收涂料。CAB-O-SPERSE 分散剂不含其他分散剂，具有静电稳定性，并且适用于多种 pH 值、金属氧化物粒度和固体重量百分比。
用于商业印刷的水性喷墨
喷墨打印已迅速成为许多成像应用的领先打印技术。它是数字化的，旨在减少设置时间并更具可定制性。此外，与溶剂或 UV 基喷墨油墨相比，水基喷墨配方更安全，使其成为纸张或塑料食品包装和摄影图像的理想解决方案。
什么是吸墨涂料？
喷墨接收涂层位于基材的顶部，该基材是不可渗透的或太多孔而不能用喷墨印刷。涂层控制墨滴的扩散，同时吸收其载体流体。它减少了实现所需光学密度所需的油墨量，并因此改善了印刷图像油墨的干燥时间。
HOW DOES INK RECEPTIVE COATING WORK?
Ink receptive coatings deliver blacker blacks, more vibrant colors, rub/mar resistance, optimal adhesion, and formulation flexibility. These type of coatings are specially designed for films, textiles and paper. They work well on banners, packaging, textiles, wallpapers, banners, labels, foils, etc. They can be applied by a variety of methods: rod coating, gravure/roll, knife coating, curtain coating, slot-die coating, even spray coating.
CAB-O-SIL FUMED SILICA
We offer a range of CAB-O-SIL® fumed silica and SpectrAl® fumed alumina performance additives that can be used in inkjet media applications. These additives achieve high absorptive capacity very efficiently, enabling excellent image quality and gloss. We are continually adding new products to better address this application’s specific needs.
LOWER VISCOSITY CAB-O-SIL FUMED SILICA
CAB-O-SIL® MS-55LV fumed silica is our newest product for the ink receptive coatings application. Compared to our standard CAB-O-SIL® MS-55 fumed silica, this product forms lower viscosity dispersions enabling higher loadings of silica resulting in a more efficient ink receptive formulation. We also offer sample formulations to support industry partners achieve differentiated performance through inkjet receptive coatings for water-based inks.

CAB-O-SPERSE FUMED SILICA AND FUMED ALUMINA DISPERSIONS
CAB-O-SPERSE® aqueous dispersions reduce formulation processing time by providing fumed silica or fumed alumina in an easy-to-use, water-based system. The dispersions are dispersant-free, electrostatically stabilized and available over a range of pH, metal oxide particle size and solids weight percent.
