EVAPO-RUST ® - Water based selective rust remover

EVAPO-RUST® is ideal for removing rust because:

• Compared to traditional acid-based or basic pickling agents, it safeguards the non-oxidized metal thanks to its selective chelating action, without requiring periodic surveillance to prevent it from corroding even the non-oxidized metal underlying the rust patina, nor the neutralization of the acid post-pickling.

• All the more so in the case of rust patina not spread uniformly over the entire surface of the metal, with consequent inevitable corrosion of the non-oxidized metal parts in contact with the acid as soon as the object to be treated is immersed in the tank.

• Compared to converters, it avoids the danger, especially in the case of thickening, that the conversion layer is unable to extend to the entire oxidized thickness, i.e. that a residual rust layer remains between the surface conversion layer and the underlying non-oxidized metal.

• Compared to both acid-based or basic pickling agents, and converters, it minimizes the structural embrittlement of the metal caused by the accidental introduction of hydrogen into the crystal lattice (hydrogen embrittlement) during treatment.

PERFORMANCE : Used by the USNavy, USAir Force, USArmy, NATO, CIA, FBI and recommended by the NRA Gunsmithing School, EVAPO-RUST® selectively removes even the most consistent layers of rust on steel, iron, cast iron and chrome.

SELECTIVE ACTION : the selective chelating agent contained in the chemical formula of the preparation removes exclusively (selectively) the oxidized layer (rust), without removing and / or damaging the non-oxidized metal substrate.

ECONOMIC : it lends itself to several reuse cycles, before the final disposal of the used solution according to the legal requirements. N ° 1 Lt. of EVAPO-RUST® removes up to 60 gr. of anhydrous rust.

SAFE : non-flammable, non-toxic and / or harmful, non-corrosive, non-irritating to the skin and eyes, non-sensitizing to the skin, does not produce fumes, unpleasant odors, Volatile Organic Compounds (VOCs) does not contain acids, alkalis or substances dangerous to according to Annex XIV (SVHC), Annex XVII biodegradable and 100% water-soluble.

EASY : no special equipment. Not applicable by brush (unless the end user has the patience to continue applying EVAPO-RUST® by brush on the rusty piece until the oxide is completely removed; feasible only for very thin oxide patinas).
