Simple 'Dip & Coat' method

SD “Cold-Ox” System

“Cold” Black Oxide Solution developed with the Hobbyist and Small Production Shop in Mind

A “Cold” Black Oxide Solution (similar to Parkerizing) developed with the Hobbyist and Small Production Shop in mind brought to you through years of research and experience in the metal finishing industry. Safely produces a firmly adherent black oxide coating on steel surfaces as an alternative to the hot caustic processes. This process does not contain cyanides or organic complexants.  The coating is integral with the steel surface with no dimensional change.  It is ideal for the small or large volume user alike. Parameters are the same for treating one screw or one hundred thousand screws.  Safely and easily produces a rich black oxide coating on all types of Steel and Cast Iron except Stainless Steel.  Hardened and High Carbon Steels can be treated without loss of strength or embrittlement. Dilute with tap water to make 4 times the volume of the concentrated solution.  The 4-litre SD Cold-Ox kit (1 litre concentrate) will cover at over 4 square metres per litre of concentrate or 36 square feet.  Kit contains all necessary chemicals for the job – “Klene-OX 8000” Degreasing/ Cleaning Solution – “Cond-OX” Metal Conditioner – “Cold-OX” Black Oxide Solution – “Seal-OX21” Protective Sealer – Instructions and 4 plastic containers (containers only available for the 4 and 22 litre kits).  

Can be used on Fasteners, Car and Motorcycle Components, Steam Engines, Gun Barrels and accessories, Engineering and Model Engineering Products, Machine Parts and Restoration Work.
