SPARKLEBRITE is a range of non-leafing aluminum pigment pastes carried in isopropyl alcohol or isopropyl acetate. These grades are typically used for liquid flexographic or gravure solvent inks. Once again the standard grades have cornflake geometry, whilst those identified as "Premier" are "lenticular" and "Ultra" are advanced-lenticular.
As with the ETERNABRITE® isopropyl pastes, the SPARKLEBRITE grades can be used in aqueous inks, but again these grades have not been treated to protect the aluminum from reaction with water and special care must be taken to evaluate the gassing stability of each grade in the final ink formulation. Gassing in an aqueous system can be initiated by the use of high shear mixing.
