Flag Rust Converter 1 Litre

Flag Rust Converter is a water based heavy duty rust converter which not only neutralises and encapsulates the rust but also forms a tough and attractive black satin finish. It can be left as a standalone finish or can be overcoated with a solvent based primer or topcoat, please note that it should not be overcoated with Xylene based paints such as Protectakote, Safekote or Flag's Anti Corrosive QD Metal Primer. If in doubt it is always advisable to do a test patch.

Areas of Use

Interior and Exterior (nb. minimum application temperature of 10°C)

Suitable Substrates

Ferrous Metals, Can also be used to overcoat wood and plastic. If in doubt always do a test patch first.

*The theoretical spreading rate has been calculated for the stated volume solids and dry film thickness. A practical spreading rate will depend on the actual dry film thickness, the nature of the substrate, and the relevant consumption factor. The physical constants are subject to normal manufacturing tolerances.

Surface Preperation

Ensure surface is free from all flaking material, dust, dirt, oil and grease. Metals (especially new/forged items) may require degreasing. Do not apply in temperatures below 10 degree centigrade.
