Abstract

Procedimiento para la fabricación de medios abrasivos, caracterizado porque se aplica sobre un sustrato flexible, de forma plana, un aglutinante de resina sintética a base de una mezcla acuosa de diferentes resinas fenólicas consistente en I) al menos un resol fenólico con el que han reaccionado por adición y/o por condensación por lo menos 1,1 moles de formaldehído por cada hidroxilo fenólico de los fenoles monovalentes y II) al menos un condensado mixto a base de al menos un fenol monovalente y al menos un fenol polivalente con formaldehído, el cual por cada mol de fenol monovalente contiene 1,1 a 1,9 moles de formaldehído y por cada mol de fenol monovalente contiene 0,1 a 2,0 moles de un fenol polivalente, siendo de 00,6 a 1,5:1 la proporción molar de las cantidades empleadas de formaldehído a la suma de las cantidades empleadas de los fenoles, juntamente con granos abrasivos, y eventualmente otros aditivos y luego se seca y endurece.
