Film Velcro Disc

Film disc is one kind of velcro discs, using open sand planting method, planting the specially treated high-performance abrasive on the highly polyester film and carrying out special anti-blocking coating treatment, which can provide uniform grinding effect.

Film disc's advantage is the hidden super coated aluminum oxide corundum. The difference between it and other conventional coatings is that conventional discs have two layers of sanding surface. The outer layer on the sand paper falls down together with the sanding product's dust during sanding, which causing premature clogging.

However, film sanding disc has a hidden anti-clogging coating. This coating makes it last longer than all other traditional sand paper including the best 3M discs. Furthermore, the proprietary film backing causes a very strong bond between the abrasive and the film backing adding to its long life. Finally, the film backing and abrasive is very even, much more than conventional paper, making it much more effective during the entire sanding process.

Film discs are widely used in the grinding of automobile primer, atomic gray, intermediate paint and finish paint. And features: high grinding efficiency, good anti blocking performance, good grinding consisitency without secondary scratch, surface grinding GJ, durable.
