Burgess Marine Heavy Duty Rust Converter. This environmentally friendly water based formulation is use extensively on ships of the Scandnavian merchant fleets. Where it is tried and tested in the severest of conditions. It is also successfully used on: ships ballast tanks, steel bridges, harbour installations, oil rigs, sewage treatment works, storage tanks, structural girders, railway and motor vehicles. Application by brush, roller, or airless spray. Can be over painted by most paint types, WE recommend the Burgess range of metal Paints.
Burgess Marine Heavy Duty converter is a co-polymer latex combined with organic chelating agents designed for application to corroded ferrous substrates. It actively converts the rust present on the substrate into a stable organic iron complex. As the polymer dries it forms an impermeable barrier to oxygen and moisture effectively sealing out any further corrosion. Burgess Marine Rust Cure has an extremely low order of toxicity and does not contain phosphoric acid or lead.
Burgess Marine Rust Cure has been successfully used on the following applications:
- automotive shells and chassis,
- ships ballast tanks,
- steel bridges,
- brine tanks,
- harbour installations,
- lamp posts,
- oil rigs,
- sewage treatment works,
- storage tanks,
- structural girders
- railway vehicles.
Wire brush the substrate to remove loose flaking paint and rust, remove any high surface peaks by abrading and then wash the substrate with detergent to remove oil and grease. The surface should then be cleaned using high pressure water wash to remove the detergent and any corrosion salts. Do not remove all traces of rust, the presence of rust is necessary for the complete chemical reaction of Burgess Marine Rust Cure.
It is recommended to carry out an initial test area at all times.
This test should take place in the working conditions of application.
The topcoat system should also be tested for compatibility.
Stir the product thoroughly before use, then decant sufficient material for the operation into a suitable non metallic container. To avoid contamination do not pour any unused material back into the original bulk container. Apply a minimum of two coats by brush spay or roller allow to a wet film thickness of 60-90um per coat (20 – 30um DFT)
Brush: Application by brush is preferred for the first coat to ensure full penetration when the substrate is heavily rusted.
Roller: Use a short nap roller and apply the coating evenly, edges may need to be stripe coated by brush to ensure the substrate is completely coated.
Spray: The coating may be applied by air assisted or airless spray techniques, typical gun settings are as follows:
Airless Spray Air assisted (syphon or pressure fed):
- 100 – 130Kg/cm2 tip pressure 3.5 – 4Kg/cm2 air pressure
- 250 – 400 um tip 250- 400 um tip
- 40 – 60 degrees fan 40 – 60 degrees fan
External : An air temperature of 5 – 30oC is preferred,
avoid applying if relative humidity is greater than 80%.
Avoid applying when there is a risk of rain or condensation during the drying period.
Internal : Ensure air movement is available to remove excess moisture during the drying process.
