MASS FOR MANUFACTURING ABRASIVE TOOL Russian patent published in 2017 - IPC B24D3/28 

FIELD: chemistry.

SUBSTANCE: weight includes abrasive, epoxy resin, polyethylenepolyamine systems, organic modifier, high strength cast iron ferrite particle size D_fi=(1.2-1.5)d_A, where d_A -dispersion of abrasive, and crystalline iodine, moreover, it additionally contains a powder of grey cast iron particle size D_gi=(0.8-1.0)d_A, the following component ratio, wt %: the abrasive 40-50, polyethylenepolyamine systems 3.5-5.0, organic modifier 2.5-3.5, high-strength ferrite iron 15-20 crystalline iodine, 0.5-1.0, grey cast iron 5-10, epoxy is the rest.

EFFECT: increase in the period of resistance abrasive tool between his edits, reducing roughness treated surfaces and thickness of the surface layer with modified physical-mechanical properties, reducing relative in square surface details.
