Oxidation / Blackening Chemicals

 

Oxidation chemicals are also called as oxidation salts or blackening salts. Oxidation treatment forms a dark colored corrosion resistant coating on iron, steel and die castings. After coating, metal parts go into protective lubrication for enhanced corrosion protection. The treatment is made in strong alkaline solution at 135-145C degree of temperature. Coating is made while treatment solution is boiling.  

 

OXITH A 55 - Black Oxidation

It is a powder form black oxidation chemical product suitable for coating of iron, steel and die castings by immersion application. Metal parts to be coated have to be free from grease and rustings. Treatment is made under following conditions; % 50 chemical concentration, 135 - 145C degree temperature and 5 - 20 minutes of treating time. Coated parts must be rinsed and then must be treated with protective oil or lubricants.

 

OXITH A 65 - Black Oxidation

OXITH A 65 is a powder form oxidation chemical for coating of iron, steel and die castings by immersion application. Metal parts have to be free from grease and rustings prior to coating. Treatment is made under conditions of % 70 - 90 chemical concentration, 135 - 145C degree temperature and 5 - 15 minutes time duration. Metal parts must be rinsed after coating and then must be treated with protective oil or lubricants as post treatment.

 

OXITH A 75 - Blackening Compound

It is a powder form black oxidation chemical product suitable for coating of iron and die castings. Coating is formed in high alkaline solution by immersion application. Treating bath is prepared % 80 - 90 chemical concentration and metal parts are dipped in for 5 - 20 minutes at 135-145C degree of temperature. Coated metal surface must be rinsed and must be treated with protective oil or lubricants afterwards.
