Fumed metal oxides are very efficient pre-coat additives for ink adsorption on a variety of substrates.
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.
The aqueous inkjet is a printing technology for commercial, signage and packaging. It is designed to be safer to handle compared to solvent or UV based inkjet inks, making it an ideal solution for food packaging.
To solve the incompatibility issue between plastic substrates and aqueous inkjet printing techniques, an inkjet receptive coating can be applied onto the plastics to create a microporous layer to accept ink droplets.
Adding fumed metal oxide (FMO) particles to an inkjet receptive coating impart porosity when applied to a plastic substrates. CAB-O-SPERSE® aqueous fumed silica and fumed alumina dispersions are dispersant-free, easy-to-handle, ready-to-use and dust-free. A selection of these dispersions are suitable for use in some food contact applications.
