DESCRIPTION

A high quality quick drying water based ferrous metal primer, suitable for application directly to rusted surfaces, based on highly protective vinyl/acrylic copolymer resin.

PROPERTIES

Feronite Rusty Metal Primer is a true rust converting metal priming paint. When applied to rusty metal it has the ability to penetrate deeply into the rust layer and convert it into a black iron oxide-tannate complex, which then combines with the resins present to make a tough, stable, well bonded paint film. When cured, this barrier film is resistant to oxygen and to water, either liquid or vapour, and the anti-corrosive additives incorporated actively prevent further development of rust, even if the coating is damaged.

Feronite Rusty Metal Primer de-rusts and primes steel in one application, and is compatible with all types of paint for finish coating. The coating cures in a few hours, and can be applied to damp surfaces.

COLOUR

Feronite has a milky off-white appearance, which changes to black as the film dries and the reaction proceeds.

TYPICAL

USES

Steel structures

Bridges

factories

piping

building frames

window frames

wrought iron

tank exteriors

Feronite Rusty Metal Primer is especially suitable for use on partly rusted galvanised iron, as it does not contain strong acids which can attack the protective zinc coating which may remain around the rusted areas.

SURFACE

PREPARATION

Remove scale, loose rust, old flaky paint, etc, by wire brushing, wet sand blasting, or similar, leaving a coating of firmly adhered rust still in place. Wash down with water, leaving the surface damp.

APPLICATION

Stir/shake Fer Stir/shake Feronite Primer thoroughly until sediment is well mixed. Apply Feronite by brush, spray, or roller, After 10 minutes the surface will begin to dry, and for best results a second coat should be applied and worked in well with a brush. Avoid too rapid drying: in warm or windy conditions, apply a fine spray of water to slow down drying and to promote the reaction with the rusted surface.

CLEAN UP

Wash all equipment with water and allow to soak overnight to remove all traces of primer.

TOPCOATING

After 3-4 hours the primed surface may be painted with the selected topcoat system. Two coats of finish paint are recommended. All oil based or solvent type paints are compatible. Exercise care in selection of water based acrylic or vinyl paints, as most are permeable to water vapour and therefore do not provide adequate protection to steel surfaces, Feronite will provide protection for up to 12 months without top coating.

THEORETICAL

COVERAGE

8 - 10 m² /litre, depending on the severity of the surface rust.

PRECAUTIONS

Feronite Rusty Metal Primer is non-toxic and non-flammable, but is very mildly acidic. Avoid breathing vapours and avoid direct contact with skin and eyes. Wash Feronite from skin with soap and water, Treat splashes in the eyes by washing immediately with water and eyewash solution. If ingested, do not induce vomiting and seek immediate medical advice. Only use in a confined space if operator is wearing full protective breathing equipment.

REFER TO FULL MATERIAL SAFETY DATA SHEET BEFORE USE.

EXPOSURE TESTS

Feronite has resisted 400 hours exposure in neutral salt spray test when overcoated with suitable topcoats. In sub-tropical outdoors exposure, both unprotected primer and fully painted samples remained unchanged after 1 year

.

FIRE RETARDANT PROPERTIES

Feronite Primer is flame retardent on non-flammable substrates, giving a Class 1 grading to BS 476 Part 7 1971 Surface Spread of Flame test.

SERVICE TEMPERATURE

Feronite Primer is not suitable for use on substrates continually above 60'C. For such service, use Feronite Rust Converter topcoated with approved high temperature primers and topcoats

.

PAINT COMPATIBILITY

Feronite Primer is compatible with most conventional topcoat paints, however metal or chromate containing paints should not be used.

STORAGE

The shelf life of Feronite Primer is 12 months  at 20 - 25 'C from the date of manufacture and should be used within that period. Higher storage temperatures will reduce the shelf life, e.g. 6 - 8 months above 30'C.
