Armourspray® powder coatings have a multitude of uses over various substrates including steel and aluminium. Examples include: platform signage and train components, bus shelters, security lockers, telephone boxes, road and general signage, roller shutter doors, transformers, and furniture for industry and schools. Potential applications include areas in public buildings and recreation grounds such as toilet and shower cubicles, wall partitioning, food court benches, outdoor/street furniture, fixtures and fittings.
Ideal for application over:
Durable Polyurethane thermosetting powder
Armourspray
Solid, Pearlescent or clear look
Satin and gloss finishes
Interior and exterior use
The pre-treatment process must be capable of meeting the performance outputs as described in AS3715
Compliance to appropriate process parameters is essential in ensuring compliance to etch, conversion coating weights (time/concentration) and conductivity of the final rinse.
The etch process is a very important stage of pre-treatment and close consultation with your pre-treatment supplier is strongly recommended to ensure optimum adhesion & corrosion resistance is obtained. As an approximate guide:
This is the next pre-treatment process for aluminium to ensure that it is suitably prepared for coating. It is recommended that Chrome conversion weights shall be a minimum of 431mg/m2, but advice from pre-treatment suppliers should be taken into consideration.
Final rinse is to ensure optimum surface preparation prior to coating.
Care should be taken with handling to ensure health and safety measures are met and that the substrate is not contaminated.
Dry Off Oven (if applicable)
If your site uses a dry off oven to assist in the pre-treatment process please ensure:
Steel substrates shall be prepared as follows:
1. Wash and degrease all surfaces to be coated in accordance with AS1627.1 with a free-rinsing, alkaline detergent, in strict accordance with the manufacturer’s written instructions and all safety warnings.
2. Wash with fresh potable water and ensure that all soluble salts are removed in accordance with AS 3894.6 methods A&D.
3. Grind all sharp edges with a power tool to a minimum radius of 2mm.
4. Power tool clean welds to AS1627.2 Class 2 to remove roughness. Remove filings, preferably by vacuum or compressed air.
5. Abrasive blast clean all steel surfaces to be painted in accordance with AS1627.4 to visual standard AS1627.9 Class 2.5 (equivalent to ISO8501-1, Sa 2.5: Very Thorough Blast-Cleaning). Use a medium that will generate a surface profile of 35 to 65 microns (as tested to AS3894.5 Method A.) In situations where it is not possible to prepare your item on all surfaces as described above, for long term protection against corrosion it is strongly recommended whenever possible, that an alternative substrate such as, aluminium be considered.
6. The steel is to be stored in an area which is clean and dry
7. The steel must be coated within 4 hours of blasting.

The table references AS2312.1, AS 4312 and ISO 9223 to identify the environment, conditions and atmospheric corrosivity categories.
Use the following table to help identify where Armourspray can be applied on aluminium projects, the system required and the Dulux Alumi Shield™ warranty level available. Refer to the conditions information to determine the environment that your project will be exposed to.
Use the following table which references AS2312.1, AS 4312 and ISO 9223 to identify the environment, conditions and atmospheric corrosivity categories
To pinpoint your projects corrosivity zone this table should be used together with the corrosivity zone maps contained within AS 4312.
1. Geothermal environments greater than 500m of a bore, mud pool, steam vent, or other source with a pH between 5 and 9. For pH outside this consult Dulux.
2. Geothermal hot spots within 500m of a bore, mud pool, steam vent, or other source.
3. All offshore islands including Waiheke Island, Stewart Island, Fraser Island and Pacific islands eg PNG, Fiji, Samoa, Tonga, Tahiti, Noumea
4. The corrosion rates for the first year of exposure for the different corrosivity categories of Aluminium and Carbon (Mild) Steel are determined by the following standards:
AS 4312 – Atmospheric corrosivity zones in Australia.
AS 2312.1- Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings. Part 1: Paint coatings
ISO 9223 – Corrosion of metals and alloys – Corrosivity of atmospheres – Classification, determination and estimation
5. The corrosion rates for the first year of exposure for the different corrosivity categories of Aluminium are determined by the following standard:
ISO 9223- Corrosion of metals and alloys – Corrosivity of atmospheres – Classification, determination and estimation
