3M's 237AA Trizact material is an embedded aluminum oxide grit in pyramid shapes on the surface of the belt. The 237AA material is a cloth backed belt that requires less pressure than the 272LA Trizact material and will generate less heat while grinding. They are excellent for creating fine finishes on your glass surfaces as a prep for final polishing or fire polishing.
- 3M's 237AA Trizact material is an embedded aluminum oxide in a randomized pyramidal structure for quick abrasion to surfaces
- The 237AA Trizact is coated onto a cloth backing for a sturdier structure that requires less pressure for grinding and therefore generates less heat on your glass
- The greater backing pressure allows the belt to break in faster with less pressure from the operator. Adding extra pressure to the 237AA belts will only wear them out prematurely
