SD Cold-Ox (Hand Apply on Mild Steel)


Cold Ox is traditionally used in Engineering to Blacken components that need mild corrosion resistance, and minimal light reflection, the method used to achieve this is normally by using a 4 stage process Black Oxide Kit, Clean, Condition, Blacken and Seal, In recent years Black Oxide has become very popular for producing an Industrial look for furniture, Stair cases, Kitchens etc. in fact the list of items that it can be used on grows month by month, for an Aged Industrial Appearance Cold Ox can be applied by hand using a low pressure atomiser, cloth or brush.

You can also create artistic effects when applying by hand, by using various cleaners to prepare the metal, letting it dry and then apply the Cold Ox, always experiment first on a cut off which is the same metal, and you will be able to create great designs. It is very important that whilst applying the room temperature will need to be a minimum of 27°c.

This product can also be bought as a replenishment for use in our Black Oxide Kits

Below are some images of what can be achieved by hand application, preparation and metal quality are big factors in what the end product will turn out like










Once you have blackened and have the effect you want, it is important to seal the colour in, for that there are some option

    excellent product

    Having used this product for the commercial production of dining and coffee table bases in raw steel, I can confirm that it works very well. However, in order to obtain a uniform matt black patina, several coats are required

    I think it is a process which needs experience to get optimal results. But it did want I wanted.

    I&#039;ve tried a large number of cold blueing solutions over the years. This is the first one that (a) goes on evenly and (b) stays on. Thorough cleaning and degreasing are absolutely essential

    Great quality product, good service and a very fast delivery. This cold oxide blackener gave the perfect finish we needed to apply to a steel sculpture we were commissioned to make. I would definitely recommend this to anyone in the business.
