These 3M™ Micron-finishing Film belts are made in England with high strength film backing and micron-graded aluminum oxide mineral. They are waterproof and provide a uniform, close tolerance finish. They have a proprietary lubricated Aluminum Oxide sanding surface which is excellent on steel. The 5 mil flexible poly backing has a friction coating on the back that resists slipping.
