The SIL-O-WET grades are treated with a chemical inhibitor to limit the reaction of aluminum in an aqueous system, and as such are one of Silberline's recommendations for water-based ink applications.  The grades are presented as an isopropyl alcohol paste, recommended for flexographic and gravure ink formulations.  The degree of gassing stability achieved with the SIL-O-WET grades is system dependent and must be evaluated for acceptable stability in the finished ink.  High shear mixing will reduce the effect of the chemical inhibitor used and damage the aluminum flakes and should therefore be avoided.
