Product Description





A MODIFIED NANODIAMOND MATERIAL OF RDDM GRADE

 

 

 

RDDM is a promising material for final polishing of hard metals, alloys, ceramics, ferrites, optical glass, gem stones (including diamonds).

One of the important effects of using small fractions of RDDM in polishing is to obtain precision mirror surfaces, including hard and super hard materials, with an increased rate of removal of a polished material.

An increased rate of removal of a treated material is typical for all fractions of RDDM material.

Technical characteristics of RDDM fractions are given in the Table below:
