Abranet NC has been developed for sanding material that should not be contaminated by corrosive agents. The preparation of corrosion - sensitive surfaces requires abrasive products containing as little heavy metals as possible. Special procedures have been carried out in the Abranet NC production process to reduce metal content and ensure consistent quality. Due to its construction, Abranet NC has significantly lower amounts of heavy metals than similar traditional abrasives. Abranet NC is suitable for sanding aluminum and aluminum parts painted in automotive processes.
