Rust Converter Primer Chemically Converts Rusty Metal BRC 6000
Designed for use on rusty metal substrates, to chemically convert rust on metal into a stable element. BRC 6000 then locks the conversion within a highly water-resistant acrylic resin system by lightly wire-brushing the surface to be converted, prior to applying BRC 6000.

BRC-6000 Rust Conversion Primer is designed to chemically convert the iron oxide surface of the rusty metal to a stable material called iron tannate. Iron oxide will continue to rust and needs to be treated to stop that process. Some companies use chemicals like phosphoric acid to accomplish this but the only true conversion occurs in the presence of a tannic acid which is used in BRC-6000. Simply brush the rusted surface lightly to remove loose rust, wash with clear water to remove any soluble salts, let dry and then coat with BRC-6000. The conversion happens as the liquid turns from gray to black. BRC-6000 also contains a latex polymer that then acts as the primer. In normal atmospheric conditions, topcoat BRC-6000 as soon as it is dry. In very harsh applications, another primer, like Steel Plus Epoxy Primer may be needed over the BRC-6000 for longest term protection.
Rusty steel is coated with iron oxide which forms a film on top of the steel substrate. For Burke Industrial Coatings BRC-6000 to work best, it is necessary to break the surface tension of this iron oxide film prior to applying BRC-6000. This can be accomplished by light wire brushing the surface to be converted. Also be sure there is no grease, oil or other compounds by washing the surface with Burke Industrial Coatings BC-4000 Cleaner. BRC-6000 will convert tight rust. Rust that is flaking or peeling must be removed to a tight substrate before treatment.
How to Apply Rust Converter Primer:
Stir BRC-6000 thoroughly. BRC-6000 should be either brushed or sprayed to thoroughly wet and cover the surface to be treated. When brushing, brush a heavy coat in one direction only. Do not brush back and forth. When spraying, apply BRC-6000 at the point where it begins to run for proper saturation. Thoroughly coat all edges, threads, bolts, and angles. Apply only when air and surface temperatures are between 50°F and 100°F and the surface temperature is at least 5° above the dew point. When brushing, do not work out of shipping container. Pour into another container. If you have material left over, do not dump back into a shipping container as it may contaminate unused product in the shipping container.
Equipment Recommended for Applying Metal Rust Converter:
Brush On: Use good quality synthetic bristle brush.
Spray On: An air, airless or air-assisted airless. Can also be applied in field applications with a backpack or pump up sprayer. For airless use .015 to .017 tip at1500 psi.
Rust Converter Appearance: Milky in the container. Black when dry.
Rust Converter Recommended Topcoats: Superlife 316 DTMR, Steel Tuff-316, Acrylic Topcoat 1010, and Steel Plus epoxies.
