ABOUT CITRISURF PRODUCTS

The CitriSurf® citric acid cleaning and passivation process is based on a new technology using safe and environmentally friendly citric acid to remove the free iron from the surface of stainless steel and chromium enrich the surface.

Austenitic stainless steel surfaces can be made highly resistant to corrosion if it is properly cleaned and passivated prior to use. Organic acids have been found to be much more effective than the traditional toxic mineral acids such as nitric acid. In addition, citric acid does not pose the environmental hazards that are present with nitric and other mineral acids.

Even with austenitic stainless steel, such as the 300 series, once a corrosion site has started it only gets worse, being continuous and self-catalyzing. In corrosive environments the growth of the corrosion site will accelerate rapidly! Thus, proper cleaning and passivation of surfaces prior to use is essential to achieve maximum resistance to corrosion.

CitriSurf® solutions provide the maximum protection by providing:

• Improved removal of free iron from the surface
• Faster removal of free iron from the surface
• Low hazard chemistry
• Environmentally safe chemistry
• Lower cost
• Passivated surfaces that pass all salt spray, immersion and high humidity tests
