NU-Blak modern, permanent liquid oxidant, 100 ml pack. Designed for spotting on worn or damaged parts of weapons. Oxidized gives the steel surface a black matte shade. By means of the process, a black decorative coating with a thickness of 1.3-3 μm is obtained. The blackening process does not significantly affect the size of the oxidized object.
Oxyda cold - a blackening system for metals, cast iron using the „Blackfast” method of the English company Blackfast Chemical LTD (a leader in the field of blackening at room temperature). Until now, oxidation was possible using expensive equipment by boiling in chemical solutions at high temperatures of 140 ° C. This made impossible the oxidation process on its own.
Process of cold oxidation - before oxidation, oxidized metal surfaces should be cleaned of rust, dirt, grease with the NU Blak Nr 16 degreaser made by Blackfast. For the oxidation process, it is necessary to physically and chemically clean the metal surface. If necessary, first use a rust remover.
Oxidation steps:
1. apply NU-Blak No. 16 degreaser to the metal surface to be oxidised.
2. remove degreased with a dampened cloth.
3. Using a clean cloth, apply NU-Blak Liquid oxidizing to the surface to be oxidised. Wait 3-5 minutes.
Apply the oxidiser several times until a nice black coating results.
4. remove the excess NU-Blak Liquid with a clean wet cloth or wash under running water.
5. For protection against corrosion, use Brunox® Gun Care Spray. Remove excess oil after use.
6. the oxidation process has been completed.
