Ultra Fine 5″ 125mm A5 PSA Polishing Disc
Conventional coated abrasives tend to dull quickly in a glass repair operation. 3M’s unique Trizact™ Structured Abrasive Film provides long lasting, consistent cut and finish while minimizing the abrasive disc change-over and slurry clean-up.
Trizact abrasives are made using a process of microreplication, whereby tiny 3D pyramids of fine grade abrasive mineral are uniformly distributed over the surface of the backing. As the top of these pyramids wears away, fresh cutting mineral is continually exposed to ensure a fast, consistent cut rate that easily removes defects such as scuffs, scratches and acid marks on shop fronts, table glass, windscreens, architectural glass and more to leave an extremely fine finish.
Scratched Glass Repair Process
Refine scratches, remove defective AR coatings using 3M™ Trizact™ Film Disc (Grade A5) Use the A5 disc to further refine any scratches left by the A10 disc. As in previous steps, apply a small amount of water to start the cutting action. Avoid extended dwell time to minimize heat build-up.
An aluminium oxide disc, Trizact 268XA effectively levels or touches up surface imperfections.
3M Trizact Discs are suitable on all acrylic & polyester solid surfaces including Corian®, Hi-Macs®, Staron®, Infinity®, Formica® Solid Surfacing, Wilsonart® Solid Surface & Freestyle®.
