Compounds, Dispersions & Emulsions for Inks and Coatings

PTFE in Ink Vehicles

FluoroSPERSE dispersions incorporate high quality PTFE found in our SST series in a variety of heat-set and sheet-fed vehicles, including viscoelastic hydrocarbon varnishes, linseed oil, lithographic oil and soya varnishes. The line is comprised of white or toned PTFE providing exceptional slip, rub resistance, and increased efficiency in high volume, automated printing ink manufacturing processes. FluoroSPERSE dispersions are available in paste or pumpable form.

PTFE in Water

Shamrock’s AquaFLON series is engineered to overcome the inherent incompatibilities between micronized PTFE and water. Ranging from micron-sized dispersions to sub-micron emulsions, these high solids, ready to use lube packagaes provide optimum slip and mar resistance in aqueous systems. They are designed with features optimized for easy incorporation into water based systems.

Wax in Water

The Hydrocer product line incorporates micronized wax powders from our S-series waxes in a pre-wetted form to provide maximum handling efficiency with performance properties such as controlled slip, abrasion resistance, and release. If these products separate, simple mixing with paddle or propeller mixer, is all that will be required to redisperse.

Wax Compounds

Wax compounds are prepared by crystallization of wax from solution to obtain fine particles. Shamrock’s CeraSPERSE line includes dispersions in hydrocarbon varnish, linseed oil, lithographic oil and soya varnish. They may be added directly into the mixing container. These products provide excellent slip and rub resistance at addition levels of 5-8% based on formulation.
