Duram NS1 Rust Buster is a rust converter and primer that stops rust in its tracks with its proven corrosion-fighting properties. Scientifically formulated, NS1 Rust Buster chemically reacts with rust and converts it into a stable, solid compound that’s ready for further priming and painting. The liquid is cream coloured and turns blue-black when reaction is complete.

Features & Benefits

• Convert rust to a stable compound on a variety of metal surfaces
• Neutralises the iron oxides that cause rust and then turns the rust into a solid compound
• Saves time, money and labour
• Quick and easy to apply
• Non-toxic
• The converted rust is ready to be primed and painted with Duram’s range of NS metal coatings
• Compatible with most paints
• Low water permeability
• Hard and flexible
• Resistant to flash rust and chemicals
• Passes Fire Resistance BS 476, Part 7 with a class 1
• Water-based, so equipment can be cleaned by rinsing it under cold water
• Cream coloured, turns blue-black when reaction is complete

Coverage

• 12 – 14m² per litre per coat. Applied in a 1 coat application

Surface Preparation

Prep

Weathered metal (rusted):

• Ensure all substrates are thoroughly clean, sound, dry and free from any contaminants such as dirt, salt, algae and grease
• Remove loose, flaking paint and rust by wire brushing, chipping or sandpapering
• Clean away sanding dust, grease and dirt with Duram NS2 Galvanized Iron Cleaner according to instructions
• Rinse thoroughly with water, especially in heavy industrial and marine atmospheres, until a water break-free surface is attained and allow to dry
• Stir or shake Duram NS1 Rust Buster thoroughly before use
• Apply one generous coat of NS1 Rust Buster to rusted, dry metal surfaces using a stiff brush as it assists penetration of the solution into the rust. It is also possible to use a soft brush, roller or airless spray, or by air assisted spray if thinned. Surface will turn blue/black in colour in 2 - 3 hours as the chemical reaction takes place. If NS1 Rust Buster is applied to a non-rusted surface, NS1 Rust Buster will remain clear
• Do not apply on hot surfaces above 40ºC

Prime

Weathered metal (rusted):

• Abrade lightly (after 2 - 3 hours)
• For optimal protection against corrosion, apply Duram NS4 Anti-Rust Coating according to instructions before applying the topcoat (especially for humid and coastal environments)

Protect

Weathered metal (rusted):

• Decorate and protect metal with Duram NS8 Metal Topcoat or other suitable paints
• Paints that can be used to overcoat Duram NS1 Rust Buster include alkyds (enamel paints), epoxies, vinyls, nitrocellulose (lacquers), polyurethanes, acrylics and water- based systems
• NS1 Rust Buster may bleed through the first coat of water-based systems
• Before overcoating with acrylics and water-based systems, first apply a coat of solvent based Universal Undercoat to prevent bleed through

Cleaning

• Use water to clean equipment and spills
• Remove spills with water or methylated spirits immediately
• The solution will stain concrete if accidentally spilled

Important

• Duram NS1 Rust Buster must be overcoated
• Do not apply at temperatures below 8ºC
• Not suitable for substrates continually above 60ºC

Safety Precautions

• Not for internal consumption or inhalation. If swallowed, perform gastric lavage
• Avoid contact with skin or eyes. In case of accidental contact, flush with water
• If splashed into the eye, rinse with a 1% solution of sodium bicarbonate
• Keep out of reach of children

Performance

• Salt spray: When applied to blast cleaned steel at a dry film thickness of 50 microns above the surface profile NS1 Rust Buster gives excellent barrier properties and shows minimal failure when subjected to 2000 hrs salt spray (ASTM B117)
• Rust conversion: Converts surface rust to an iron organic complex in ± 2 hours
• Flexibility: 6mm bend (Pass)
• Hardness: Falling weight test, 3mm indent (Pass)
• Scratch resistance: 2000g
• Resistance to flash rust: Excellent
• Fire resistance: Passes BS 476, Part 7 with a class 1
• Chemical resistance: Resists spillage of strong acids, alkali’s, aliphatic solvents, alcohols, petrol, crude oil and diesel. Not resistant to aromatic solvents, animal and vegetable oils.
