Micro-replication

Trizact

3M™ Trizact™ Film

3M has pioneered the use of tiny, precisely shaped structures to give materials new physical, chemical or optical properties. Micro-replicated prisms are used in road signs, electronic displays and exterior building illumination to capture and reflect light more brilliantly. Minute pyramids make 3M's structured abrasives work better and wear more evenly. And micro-replicated channels can even direct fluids using capillary action, an application with enormous potential for biomedical products.

Reinventing abrasives

Ever wonder how your golf club was made? Answer: with a lot of sanding and grinding. 3M was a pioneer in abrasives and continues to innovate using micro-replication technology - a technology also used in applications from health care to traffic signs. Unlike conventional abrasives, which feature randomly arranged minerals, the micro-replicated grains found in 3M™ Trizact™ abrasives are precisely arranged in shaped structures, resulting in more predictable finishes and consistent quality.

Combined with:

surface

Micro-replicated precision

Structured abrasives feature an engineered surface of microscopic three-dimensional structures often resembling pyramids. This precise and consistent abrasive surface is ideal for metal-finishing applications that require a fine finish.

The bottom line

As 3M™ Trizact™ abrasives are used, the tops of the tiny structures wear away, continuously exposing fresh mineral. This provides a fast and extremely consistent cut rate throughout the long life of the abrasive. For industrial users, these features mean more parts are finished faster.
