Soytab™ FFG free-flow gel Web News Extender
Soytab Extender FFG is a close relative of our 30+ year-old standard, Soytab Extender. Both extenders are used as either letdown varnishes or as transparent white extenders. Both also have nearly zero VOC's and are soy oil-based.
The main difference with Soytab Extender FFG in comparison to our standard "Soytab Extender" is that although it is a gel, it is softer in body and does not develop a high-structure ink like standard Soytab Extender can. This is particularly advantageous if you are formulating for more modern higher-speed presses that use pressurized ink delivery systems from tanks or large tote bins.
Soytab Extender FFG is used in the manufacture of soy oil-based web offset news inks. Soytab Extender FFG, as the name implies, is soy oil-based, containing approximately 40% soy oil. Soytab extender 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.
