## Description

FUCHS ANTICORIT AQ 1961 R is an aqueous organic corrosion inhibitor for the protection of ferrous metals. It forms a thin, transparent dry film after application. The film permits direct welding, and most coatings can be applied directly onto the film without prior removal, effectively simplifying production processes. Barium-free, it provides excellent corrosion resistance and is suitable for a wide variety of process conditions. It delivers particularly outstanding protection for porous metal surfaces such as castings and forgings.

## Features

FUCHS ANTICORIT AQ 1961 R is suitable for in-process corrosion protection and final anti-corrosion treatment at the end of washing and dipping lines. It can also be used as a leak-testing medium and grinding fluid, or added to synthetic coolants and alkaline cleaners as an anti-corrosion additive.

It forms a transparent, dry, oil-free and non-tacky film. No cleaning is required to remove the protective film before welding or painting.

When used at a concentration of 3% or lower, it is compatible with refrigerants for air-conditioning compressors and provides corrosion protection for AC compressor components.

Barium-free for better environmental safety. It achieves excellent rust prevention on porous metal surfaces such as castings and forgings.

Applicable industries: metalworking, automotive, foundry, forging, mechanical equipment, iron and metallurgy.
