MM Ligno is tailored for wood sanding applications. Fast and even cut thanks to special hourglass abrasive pattern, long service life with good resistance to clogging. Specially developed latex-impregnated paper for flexibility and edgewear resistance. Its dust channels 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.
