Trizact™ is a product developed by 3M corporation. It is a micron-graded abrasive, available in A35, A20, A10 and A5, and is produced by microreplication of microscopic three dimensional structures applied to a thin film backing in a precise pattern. Trizact™ consists of precisely shaped pyramids of fine grade mineral. The “A” in the grit size designation stands for “Apex,” as that is the structure of this material.
