SoyaSpersion 4281 YS Rhodamine Red is a multi-purpose dispersion of 36.5% Red 81 (Rhodamine YS) pigment in a near-zero VOC, bio-based litho vehicle for paste inks. SoyaSpersion 4281 YS Rhodamine Red can be used alone for making many types of Rhodamine Red 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 Rhodamine Red inks, 35% to 55% of SoyaSpersion 4281 YS Rhodamine Red by total formula weight is considered a normal loading for most paste ink formulas. It may be necessary to incorporate a small percentage of SoyaSpersion 8238 BS Purple along with this product to achieve correct color hue.
