DINITROL RC 900 is a rust converter based on organic chelate complex combined with epoxy resin. It actively converts the rust on the substrate into a stable organic iron complex. When the product dries, it forms an impenetrable barrier to further corrosion. DINITROL RC 900 penetrates about 7?10 times deeper into the rust than conventional rust conversion products and forms a dry and strong adhesive film that is suitable as a base for the lacquer structure and as a carrier for other corrosion protection products.
Polymer film formed on converted rust
Deep effect
Easy application
Deep working properties
DINITROL RC 900 is designed for use on oxidized iron parts.
Method of use
Remove rust, grease and dirt with a wire brush, sand paper or a sandblasting process. Rust and scale may only be visible as slight shading. In addition to rust, the steel must also be free from dust and grease. Carefully clean with acetone or lacquer thinner. Shake the spray can well. The product should be applied in several successive coats, at a distance of approx. 25 cm.
The metal temperature should not be below 10°C. The material is dust-dry after one hour, if necessary, a further coat can be applied.
Pre-treatment Substrates
DINITROL RC 900 should be applied to corroded surfaces. Loose rust must be removed before processing.
Over-Coating / 2-Layer-Application
DINITROL RC 900 can be overapplied with most DINITROL Corrosion Prevention products and with most common complete paint systems. For additional information, please consult DINOL GmbH.
