Flex LB is a multi-purpose and long-lasting abrasive suitable for countless applications. It has a quick cut and a very homogeneous finish thanks to the special aluminium oxide granules distributed with a new generation system. It has a paper support, semi-open sprinkling and new calcium-based stearates (in the P80-P180 grains) and zinc-based (in the P220-P800 grains) that improve the inlay resistance by prolonging the effectiveness of the abrasive and increasing the quality of the finishes. Velcro system.
