Fine polishing suspensions for perfect metallographic sample preparation

QPREP fine polishing suspensions are the polishing products of choice for the most demanding polishing requirements. This involves chemical mechanical polishing using silicon dioxide or aluminum oxide.

Product Advantages

Highest surface qualities
Removal of all deformation with vibration polishing
Polishing/removing scratches in the range of 0.1μm to 0.05μm

Recommended applications

Detailed microstructure analysis
Very soft or very hard and ductile materials
