Soytab™ LO VIS high flow Web News Extender
Soytab Extender LO VIS (Extra Long Flow) is a close relative of our 30+ year-old standard, Soytab Extender. Soytab Extender LO VIS's main feature is that it is very soft in body and has a very low viscosity. Soytab Extender LO VIS can be used as either a letdown varnish or as a transparent white extender. Soytab Extender LO VIS has nearly zero VOC's and is soy oil-based. One can tip over a drum, and Soytab Extender LO VIS pours out immediately.
Use Soytab Extender LO VIS for developing newsinks for modern high speed presses that use "injector" type ink fountains. Soytab Extender LO VIS is particularly well-suited for use in making inks for keyless inking systems. Newsinks made with Soytab Extender LO VIS exhibit very good long-term control of viscosity, avoiding viscosity "creep" during extender periods of storage. Soytab Extender LO VIS is particularly good for making viscosity-stable Process Red (magenta) inks.
Make sure to pre-mix Soytab Extender LO VIS thoroughly before using it, as some settling of pigment solids in Soytab Extender LO VIS may occur during long-term storage. For best performance, please avoid using any form of castor oil in process reds.
Soytab Extender LO VIS has 100 percent solids and is virtually VOC-free. It is used as an excellent letdown vehicle for making all kinds of no heat web news inks when combined with just about any type of flush.
For best performance, please avoid using any form of castor oil for water pickup control in process reds.
