Dri-Rx® HF

by Borchers (Milliken)

Dri-Rx® HF by Borchers (Milliken) is a drier accelerator. It enhances drying performance in solvent- and water-borne air-dried paints, coatings & inks. It is an organic compound that works synergistically with cobalt, manganese and other oxidative (transition) metals to speed up the drying process in hard-to-dry and thick film applications. <ul style="padding-left: 40px;"><li>It increases oxidative activity while reducing susceptibility to hydrolysis and the loss-of-dry phenomenon that occurs through metal adsorption.</li> <li>Dri-Rx® HF is suitable for architectural paints, industrial coatings, stains and printing inks.</li> <li>Recommended usage level in high solids paints is 0.2% on vehicle solids, water-based paints 0.2-0.5% on vehicle solids and in slow drying inks 0.1-0.5%.</li></ul>
