SO VCI® Surface treatment liquids: cleaners, rust removers and rust convertor

A clean, rust-free surface is where protection starts. Suprabha makes a range of liquids to degrease, de-rust and convert rust, many of them biodegradable, with inhibitors that keep the surface protected after cleaning.

Cleaning: ALC seriesNear-neutral, water-based cleaners (ALC 852 / 854 / 855 / 856) for ferrous and non-ferrous metals, and SO VCI® 418 / 448 solvent cut-back cleaner.

Rust removal: RRM seriesDip small items in RRM 422 / 423, rinse, then neutralise in SO VCI® 302 / 302V so acid drag does not cause fresh rust.

Acid tank additiveReduces metal loss, speeds de-rusting and forms a foam layer that keeps acid fumes in the bath.

Rust convertor: FEC 902For large fabricated surfaces: converts the surface rust layer into a rust preventive coating that can be painted over.

Room temperature, no fumesSolvent cut-back cleaners work at room temperature, unlike TCE baths: no power bills and minimal evaporation. Aqueous baths release no toxic fumes.

FAQ

Surface treatment liquids: questions buyers ask

Can I paint over the rust convertor?

Yes. FEC 902 converts the superficial rust layer into a rust preventive film that protects the surface underneath, and painting on it is possible.

Why neutralise after rust removal?

Acid left on the metal causes more rust. After de-rusting in RRM 422 / 423 and rinsing, parts are dipped in SO VCI® 302 / 302V neutraliser.

Do the cleaners need heating?

No. Suprabha’s solvent cut-back cleaners work at room temperature, unlike TCE baths, and the aqueous baths are near neutral and can be topped up inexpensively.

How are the baths disposed of?

Suprabha states its aqueous baths release no toxic fumes and can be disposed of without treatment through a regular oil-waste disposal system.
