Blending abrasive disc 443SA is a foam abrasive disc for scuff sanding blend panels, texture matching orange peel and removing fine grade sand scratches prior to paint blending on adjacent panels. Microreplicated 3-D mineral abrasive structures wear evenly for consistent application and longer disc life. For more predictable finishes and improved, consistent quality, 3M Trizact products feature microreplication – small 3-dimensional structures are reproduced and then uniformly distributed over the surface of the abrasive. These patterned, precise mineral structures contain multiple layers of abrasive mineral. As the structures wear, fresh, sharp mineral is exposed. The result is that the abrasive cuts faster, allows for precise finish control, and stays sharper longer – operators can even reduce grade sequences during collision repair, requiring fewer process steps and fewer abrasive products. 3M Trizact Hookit Blending Abrasive Disc 443SA works seamlessly with Hookit disc pads and interface pads for responsive application and fast, efficient changeouts during the scratch refinement process.
