Making the Ultimax Ligno, Mirka takes sustainability into focus. Using new generation technology, together with fewer harmful chemicals, abrasive grains are printed onto optimized hourglass patterns on the surface, placing them where they can perform the best. Mirka’s precise, energy saving production process also has a significant effect in creating less material waste.
Selected out of 64 different designs, the printed hourglass pattern ensures optimal cutting performance with consistent results. The segmented surface increases sanding pressure on each abrasive grain. Each segment has four sharp corners and two angled surfaces, constantly creating additional cutting edges during sanding. With Ultimax Ligno, Mirka uses a specially developed latex impregnated paper to improve flexibility and adhesion and to control edgewear, providing each abrasive with a longer service life. It is available in a wide range of grits from 40 to 400.
To resist clogging and speed up the cutting process, Ultimax Ligno utilizes Mirka’s groundbreaking Multifit hole pattern. Its dust channels leading to extraction holes take control of dust, keeping the abrasive grains cutting, and as air circulates under the abrasive it reduces heat during sanding – an important benefit when sanding substrates, avoiding turning wood dust into a clogging putty. Even larger wood dust particles are not an issue thanks to different width dust channels. Exposure to wood dust is a significant occupational health risk, meaning Ultimax Ligno is designed from the start with Mirka’s dust free sanding technology.
