Ardrox 185 Alkaline Rust & Scale Remover Powder 25Kg Bag *DEF STAN 03-2/1

Ardrox 185L is a highly alkaline concentrated solution in water containing sequestrants. It is also available as a powder under the name Ardrox 185.

Ardrox 185L is primary intended for the removal of heavy rust and scale from ferrous components in immersion tanks but it is also capable to remove oil, grease and some air-dried paints. It will not attack or cause hydrogen embrittlement in ferrous alloys and there is markedly less tendency for re-rusting to occur than with acid pickling.

When used in conjunction with the adequate other Ardrox specialties, Ardrox 185L can be used to remove scale from hot-end jet engine components. It can also be used for cleaning parts made of Titanium.

Application:

Ardrox 185L is usually used at a concentration of 30-50% by volume in water, depending on the amount of rust or scale to be removed. This corresponds to a concentration of 200 - 375 g/L of Ardrox 185 in water.

Ardrox 185 must always be dissolved in cold water. There will be an exothermic reaction and the solution will heat up to 50-60°C / 120-140°F.
