DGL Powder Coatings are an ideal choice for the long term protection of architectural aluminium items for your next project, and provide assurance through the issue of Alumi Shield Warranties.
The DGL Alumi Shield warranties are available for warranty grade DGL Powder coat products on architectural grade aluminium. Example items made from architectural aluminium include windows, louvres, doors, balustrades, decorative sheet amongst others.
The Alumi Shield Warranty is made up of two key components, a colour warranty (for fade and chalking) and a durability warranty (film integrity).

It is important to define your project correctly to ensure the correct product is specified and the performance and warranty is able to be gained for your project.
Both project type and the environment (conditions) will impact on the exposure of the powdercoat to elements such as UV, dirt and salt. For instance, marine and coastal environments are exposed to winds and sea salts, which have a long-term impact on the performance of coating systems due to erosion and weathering, and commercial projects will be exposed to greater environmental impacts, whether they be the usage of the environment or the height of the building.
To ensure products are fit for these environments DGL recommends suitable products based on the AS3715 and AAMA testing standards. These standards provide a benchmark of product quality that are an assurance that your asset will be protected by a product fit for purpose. For complete details relating to these standards visit aamanet.org
To define projects we utilise three key sources:
1. The building classifications under the Building code of Australia (BCA)
2. Industry standards for powder coatings – Primarily AAMA and AS3715
3. Environmental condition utilising AS4312 and ISO12944 Atmospheric corrosivity zones in Australia as a guide
The following tables allow you to identify your project, to look at the appropriate products for the environment, whether it be interior or exterior, the care and maintenance required, and details on our DGL Accredited Powder Coaters, as only DGL Accredited Powder coaters are able to issue our DGL Alumi Shield warranties.
Dulux Alumi Shield™ warranties are available on a wide range of fabricated architectural aluminium items, but those items must be designed, prepared (pre-treated), coated, fabricated and installed to standard ensuring that the item is fully protected.
It is essential that any item that is coated must be designed and fabricated to ensure:
Use the following table to help you identify your project and the appropriate standard a product should meet for that environment.
Definitions:
Use the following table to help identify the product choice you have for the exterior use of DGL Premium Powder coatings on your project. Refer to the conditions information to determine the environment that your project will be exposed to.
1. Fluoroset may be suitable in locations <10m from the high tide line e.g. harbours (contact DGL for advice.)
2. Electro and Duratec are only suitable for coastal environments >10m from the high tide.
Alumi Shield Warranties on perforated and expanded aluminium in exterior environments are available for the following products and conditions:
a. Mild – Electro, Duratec and Fluoroset (E-Prime base coat not mandatory)
b. Severe and tropical – Duratec, Electro and Fluoroset (E-Prime base coat mandatory)

Please refer to Exterior Environments close to liquids other than the sea section for warranty implications in such environments.
All DGL powder products are NOT suitable in strongly acidic or caustic environments so PH must be >5 and <9.
Use the following table which references AS4312 and ISO12944 Atmospheric corrosivity zones in Australia to define the environmental conditions and product is suitable for.
*Tropical projects – It is recommended to speak to a DGL Account Manager or call the advice line for all projects in Tropical locations
1. Geothermal environments with a PH>5 and <9. For PH outside this consult DGL.
2. Offshore islands that are not tropical include Waiheke, Stewart Island, Fraser Island etc.
3. Tropical islands include Australian Islands north of Mackay and Pacific islands such as PNG, Fiji, Samoa, Tonga.
AS4312 refers to the corrosion rate for steel primarily, but is used as an indicator for other metals including aluminium. For more info refer to the standard.
For powder coated assets close to liquids other than the sea, eg fences near outdoor swimming pools, fountains, outdoor bathrooms or furniture etc.
Please refer to the guidance below for your product choice and to understand the warranty limitations in these environments.

Use the following table to help identify the product choice you have for the interior use of DGL Premium Powder coatings on your project. Refer to the conditions information to determine the environment that your project will be exposed to.
All DGL powder product are NOT suitable in strongly acidic environments so PH must be >5.
Alumi Shield Warranties on perforated and expanded aluminium in interior environments are available for the following products and conditions:
a. General – Electro, Duratec and Fluoroset (E-Prime base coat not mandatory).
b. Moderate – Duratec, Electro and Fluoroset (E-Prime base coat mandatory).

Please refer to Interior Environments close to liquids for warranty implications where powder coatings may be in close proximity to liquids.
Use the following table which references AS4312 and ISO12944 Atmospheric corrosivity zones in Australia to define the environmental conditions and product is suitable for.
For powder coated assets close to liquids, eg fences, windows and doors near indoor swimming pools, fountains, fitting in bathrooms or furniture etc please refer to the guidance below for your product options for your project.

Attention to packing is essential for powder coaters and fabricators to ensure that all powder coated sections are received in good condition.
When packing powder coated assets, it is recommended that:
It is recommended in environments with low salt, low pollutants and in urban areas that cleaning should take place at a minimum of every twelve months. In areas where salts, pollutants and high corrosivity levels are prevalent, e.g. beachfront houses or industrial areas, it is recommended a cleaning program should be carried out more frequently at a minimum of every six months.
Sheltered areas can have a higher risk of coating degradation as wind-blown salt and other debris or pollutants may adhere to the surface and not be removed when it rains. These areas may require more frequent cleaning.
Use the following table to identify the recommended minimum cleaning and maintenance schedule for your project. The table references AS4312 and ISO12944 Atmospheric corrosivity zones in Australia to define the environmental conditions.
Care and maintenance schedules are essential to ensure that the life of your asset is maximised whether the project be a residential, commercial or non-habitable project. Simply follow 3 important steps:
1. Carefully remove any loose surface deposits with a wet sponge by gently rubbing.
2. Clean by gently rubbing the surface with a soft brush (non-abrasive) and a dilute solution of a mild detergent, e.g. pH-neutral liquid hand or dishwashing detergent in warm water to remove dust, salt and other deposits. For stubborn stains use only recommended solvents on the affected area, e.g. Isopropyl alcohol (IPA) or methylated spirits and rinse off with clean water. Do not use other aggressive solvents.
3. Rinse the surfaces with clean fresh water after cleaning to remove all residues.
Aggressive solvents such as turpentine, white spirits, thinners, citrus based cleaners and other aggressive solvents are harmful to the extended life of the powder coated surface. These solvents should not be used for cleaning purposes and will render a warranty void if used.
If paint splashes, sealants/mastics or stubborn stains need to be removed use only Isopropyl alcohol (IPA) or methylated spirits and rinse off with clean fresh water.
In some cases, strong solvents recommended for thinning various types of paints and also for cleaning up mastics/sealants are harmful to the extended life of the powder coated surface. These solvents should not be used for cleaning purposes and will render the warranty void if used. If paint splashes or sealants/mastics need to be removed then the following solvents can be used safely: Methylated Spirits, Ethyl Alcohol, Isopropanol.
