SoyaSpersion™ 4238 Lithol Rubine Red
SoyaSpersion™ 4238 Lithol Rubine Red is a multi-purpose dispersion of Lithol Rubine pigment in a near-zero VOC, bio-based litho vehicle for paste inks. SoyaSpersion™ 4238 Lithol Rubine can be used alone for making many types of Process Red (Magenta) 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 Process Red (Magenta) inks, 25% to 50% of VersaBase™ 4037 Lithol Rubine Red by total formula weight is considered SoyaSpersion™ 4238 Lithol Rubine Red a normal loading for most paste ink formulas.
