STRUCTURED ABRASIVE MATERIAL WITH TOP LAYER AND METHOD OF ITS FABRICATION AND APPLICATION Russian patent published in 2013 - IPC B24D3/28 B24D3/34 B24D18/00 

FIELD: process engineering.

SUBSTANCE: invention relates to structured abrasive material with top layer and may be used with, for example, rotary tool. Said structured abrasive article comprises substrate with first and second opposed main surfaces, topographically structured abrasive layer attached to said substrate. Said structured abrasive layer comprises abrasive components with exact form. Note here that said components comprise abrasive particles in cross-linked polymer binder and feature parameter D₅₀, and solid top layer arranged at, at least, portion of said topographically structured abrasive layer. Said top solid layer comprises eroding particles with Moos hardness of, at least, 4, and water soluble polymer. Note here that said eroding particles feature D₅₀, smaller than or equal to that of said abrasive particles.

EFFECT: structured abrasive material with top layer.
