Web News Extender GX 40 is an economically-priced low-odor, low-VOC extender vehicle intended for use as either a letdown varnish or as a transparent white in color mixing systems for newspaper and no heat web offset inks. Inks made with this extender will have a very "flat" finish when printed. Therefore, it is only recommended for printing on newsprint stocks.

Web News Extender GX 40 is very thixotropic, due to the fact that there is nearly 40% clay in the formula. This thixotropy can be used to produce an ink that is resistant to misting and dripping, yet ink made with GX 40 Extender will produce flow under mild agitation. Use GX 40 Extender in combination with Web News Extender FFG for news inks with properly balanced flow properties.

We recommend using his product to formulate inks for older, larger high-speed presses.
