SoyaSpersion™ 7237 Methyl Violet
Packaging Options:

SoyaSpersion 7237 Methyl Violet is a multi-purpose dispersion of 37% PTMA Methyl Violet (Phospho-Molybdic Acid Salt of Violet 3) pigment in a near-zero VOC, bio-based litho vehicle for paste inks. SoyaSpersion 7237 Methyl Violet can be used alone for making many types of strong, violet inks such as Quickset/Sheetfed Lithographic, low-VOC Heatset Web Offset, Business Forms, and Newsinks.


Additionally, the high solids content of SoyaSpersion pigment preparations permit their use for high adhesion lithographic inks intended for printing on plastic film and metal. Metallic driers such as cobalt, manganese, zirconium and cerium are particularly effective when used with SoyaSpersion products.


Typically used to make mixing Violet inks, 30% to 55% of SoyaSpersion 7237 Methyl Violet by total formula weight is considered a normal loading for most paste ink formulas.
