Removing rust without harming the environment 05 August 2022

Evapo-Rust from CRC Industries is a water-based rust remover that is biodegradable and non-toxic for the user and the environment. CRC Evapo-Rust can be used to restore metal parts and tools rapidly and efficiently in all types of industries.

Evapo-Rust is a powerful rust remover, with a water-based formula that is effective and easy to use. The part simply has to be immersed in a bath of the ready to use solution, the rust then detaches from the metal surface and remains suspended in the liquid. The active ingredient in the formula binds exclusively to iron, removing only the rust from steel, iron, cast iron and chrome. It thus preserves the non-oxidized metal and is harmless to other metals. Compared to conventional acidic or basic strippers, CRC Evapo-Rust is non-toxic, non-caustic and non-corrosive, and does not affect plastic, PVC, Viton and non-oxidized paint on treated parts.

CRC Evapo-Rust is a powerful formula that removes the thickest layers of rust down to bare metal, leaving no residual layer and requiring no sanding or blasting. The treatment is fast, a light layer of rust is removed in only 15 – 30 minutes, a medium layer in 6 hours, and a thick layer in 12 – 24 hours. It works great at room temperature; however results can be accelerated if heated to 50°C.

The same CRC Evapo-Rust bath can be reused several times, depending on the intensity of the rust layer on the treated parts, which makes it economical. 5 litres of Evapo-Rust can remove 0.3kg of pure dry rust. Moreover, preliminary cleaning is only necessary in the case of very dirty and greasy parts. Once the part has been derusted, you only need to rinse it with water. It is recommended to protect the treated part with an anticorrosion product or a paint.
