What is KELATE® ?

KELATE® is a highly reactive water reducible chelating polymer for rust passivation on rusted steel which has been hand or power cleaned, or blasted

KELATE® neutralizes the corrosion process. It reacts quickly (reaction time is +/- 3 hours) with the rust and transforms iron oxides into a stable and insoluble blue-black metallo-organic complex which is ready for painting after reaction.

The reaction is characterized by the surface turning to a blue-black colour.

KELATE® effects a thorough chemical passivation of the substrate and makes it a sound base for the application of coating systems.

KELATE® is not a paint or a primer coating. Treated surfaces must be protected by suitable paint/coatings, preferably within 48 hours after application. KELATE®MR138 will give some longer extra protection (see below).
