3M™ Trizact™, derived from patented 3M microreplication technology, is renowned for its consistency in achieving repeatable, precision finishes through the 3-dimensional shapes, which are replicated structures (micro or macro) with layers of abrasive minerals. Fresh mineral is constantly and evenly delivered to the work surface to ensure that cutting and consistency remain stable throughout the life of the abrasive. Trizact belts start sharp and stay sharp, resulting in more predictable finishes and improved, consistent quality in your parts.
