Soytab Extender is used in the manufacture of soy oil-based web offset news inks. Soytab Extender, as the name implies, is soy oil-based, containing approximately 25% 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. 

​

Soytab Extender has a short, thick gel consistency. To obtain a more free-flowing soy news extender, please see Soytab Extender FFG in this catalog.

​

Soytab Extender has a very gelled body, especially when held in comparison to its low tack. This high viscosity-to-tack ratio is especially useful for making newsinks for presses that are used in high-temperature climates, or where press conditions tend to cause the breakdown of less robust ink formulas.

​

Please consult the Formulations Guide for more extensive information and formulas using Soytab Extender. For best performance, please avoid using any form of castor oil in process reds.
