Info

OP-S NonDry/OP-SOP-S NonDry/OP-S is especially suited for polishing of very ductile metals like refractorymetals, aluminium, titanium*, tungsten, copper and other materials such as silicon. It canalso be used with the addition of reagents, normally used for the etching of the material inquestion. This increases the chemical activity, thus shortening the actual polishing time.*For the preparation of titanium we recommend using regular OP-S.ZnCuTi alloy.Polarized Lightwith sensitivetint plate, 200x.Method 1Method 2Plane Grinding Fine Grinding Diamond Polishing Diamond Polishing Oxide PolishingSurface MD-Gekko MD-Plan MD-Dac MD-Mol MD-ChemAbrasive SiC # 220 DP-Suspension, P - 9 µm DP-Suspension, P - 6 µm DP-Suspension, P - 1 µm OP-S NonDry/OP-ULubricant Water DP-Lubricant, Blue DP-Lubricant, Blue DP-Lubricant, Red -Surface MD-Piano 220 MD-Plan - MD-Mol MD-ChemAbrasive Diamond DiaPro Plan - DiaPro Mol OP-S NonDryLubricant Water - - - -OP-U NonDry/OP-UOP-U NonDry/OP-U is less aggressive than OP-S NonDry and suitable for all materials.
