POLYFLUO 190XF is a specially modified micronized fluorocarbon that will impart excellent abrasion resistance and slip to most printing inks. POLYFLUO 190XF has been processed to a 1.5-3.0 NPIRI grind gauge reading in order to eliminate the need for compounding or excessive grinding.

POLYFLUO 190XF has been designed to provide the toughness associated with polyethylene along with the slip provided by fluorocarbon when incorporated into printing inks, paints or other types of surface coatings.

POLYFLUO 190XF works especially well in letterpress and offset inks and due to its very fine particle size, it can be readily dispersed into most ink varnishes along with flushed or dry colors. This mix can then be given a normal canning or grind pass over the mill to produce an excellent grind. Using this method, POLYFLUO 190XF has shown to work very well in heat set web offset inks.

Optimum properties are usually achieved by adding 1-3% by weight. The amount will vary depending on the type of coating and the end use requirements.

At temperatures above 600°F some polymer fumes may be emitted due to decomposition of the fluorocarbon polymer. Therefore, smoking should not be permitted when working with this material.
