The 3M™ Trizact™ Finesse-it™ Film Disc Roll 464LA was constructed with a revolutionary surface topography that channels sanding debris away from the surface, significantly reducing the chance of loading and extending the life of the disc.The secret behind the longer life and faster cut of the 3M Trizact Finesse-it Film Disc 464LA lies in the precise, microreplicated system of channels that move sanding debris away from the disc. This prevents debris from building up between the abrasive structures, allowing fresh mineral to be continually exposed to the workpiece. Unlike conventional abrasives, 3M Trizact Abrasive starts sharp and stays sharp, resulting in more predictable finishes and improved, consistent quality. 3M Trizact Abrasive Discs can last up to five times longer than conventional discs and provide precise finish control. Three-dimensional structures uniformly distributed over the entire surface of the abrasive ensure consistent performance and eliminate disc-to-disc variation. The film discs are perfect for finishing, defect repair and leveling, when you're working on paint, clear coat, and plastic defect removal.The precisely graded mineral helps reduce processing steps and produces a high gloss level. Very little water is needed, making the process easy and efficient. The extended life of the film disc, paired with its fast and consistent cut, make it the perfect aid for speedy repairs.
