FLUO HT is a micronized polytetrafluoroethylene (PTFE) which has been developed for use in areas where excellent heat resistance, slip and rub resistance are required. FLUO HT has been processed to a 1.0-1.5 NPIRI grind gauge reading to allow for easy dispersion into printing inks and coatings. Due to its very fine particle size, FLUO HT can either be pre-dispersed into a paste or added directly into most inks and coatings with conventional mixing equipment.
FLUO HT is most effective when used at low levels (1/2-1%) as an additive to either our MP grades of micronized synthetic waxes or our MPP grades of micronized polyethylenes. A low percentage of FLUO HT gives the most dramatic improvement. The addition of a small amount of FLUO HT along with our grades of waxes or polyethylenes allows each material to perform with maximum efficiency.
FLUO HT is especially recommended for use in Heat-Set, Quick-Set, IR, UV and Metal Decorating Printing Inks and Overprint Varnishes.
At temperature above 600°F, some polymer fumes may be emitted due to oxidation of the fluorocarbon polymer. Therefore, smoking should not be permitted when working with this material.
