SoyaSpersion™ 8237 BS Purple
Packaging Options:

SoyaSpersion 8238 BS Purple is a multi-purpose dispersion of 37% Red 81 (Rhodamine BS) pigment in a near-zero VOC, bio-based litho vehicle for paste inks. SoyaSpersion 8238 BS Purple can be used alone for making many types of mixing Purple 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 Purple inks, 35% to 60% of SoyaSpersion 8238 BS Purple 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 4281 YS Rhodamine Red along with this product to achieve correct color hue.
