3M™ Trizact™ Hookit™ Blending Abrasive Disc 443SA works seamlessly with our Hookit™ disc pads and interface pads for responsive application and fast, efficient changeouts during the scratch refinement process.
About Our Trizact™ Abrasives
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.
Our Hookit™ Attachment System
The Hookit™ attachment system has a hook-and-loop feature which makes disc attachment, removal, and re-attachment clean and easy. It also facilitates use and re-use of the disc for maximum product life. Hookit™ sheets have a brushed nylon loop backing of the type most commonly used in everyday hook-and-loop applications. A range of Hookit™ disc backup pads features hooks which grip the brushed nylon loop backing. It’s simple: just attach the disc and start sanding. The disc removes just as cleanly and easily. The Hookit™ system is designed for work spaces and applications where adhesive backed abrasives may become contaminated by dust, dirt or debris.
