More info

ST2900 Anti-Corrosion topcoat is a specific two-component glossy acrylic clear topcoat that adheres to metals and protects against the appearance of oxidation (rust).

ST2900 Anti-Corrosion topcoat adheres directly to steel, galvanised metal, zinc, aluminium, copper, alloys and stainless steel. High resistance to UV radiation.

The anti-rust topcoat has a pigment which prevents the appearance or progression of oxidation : indeed, even if an adhesion topcoat is applied to a metal, residual oxidation can nevertheless develop under it, even if there are no visible traces of rust at all before coating. Rust will develop over time unless the anti-corrosion topcoat has been used.

ST2900 Gloss* has a good transparency (slightly less than a conventional bodywork clear topcoat).

Available in matt or satin (minimum order of 10 litres).
