Quantum FX Shimmers at DesignEX 09
DesignEX is Australia's most comprehensive interior architecture and design event that celebrates the very best in innovation. DesignEX 09 again offered aspiration through the impressive showcase of cutting edge products, exciting features and prestigious awards such as the Dulux Colour Awards. Held every two years, DesignEX 09 was revealed at the Melbourne Convention and Exhibition Centre, Southbank.
Dulux dominated the Centre with a vast display, which successfully demonstrated that Dulux is “more than just paint”. The display invited visitors to interact and touch the stand elements, each coated with a different product finish to showcase the variety of colours, textures and effects available.
Dulux Protective Coatings featured our premier metallic polyurethane, Quantum® FX. The entire “pod” was spray painted in Quantum FX Gold (41/075) and sealed in Quantum Clear enhancing the metallic sparkle. The colour complimented the Dulux hue “Tibetan Silk” on nearby product pods. World-class polyurethane technology used in the Quantum FX formulation offers the Specifier choice of detailing the metallic coating without the Quantum Clear, achieving an elegant satin finish with long-term durability, UV stability and excellent graffiti resistance.
Opposite the Dulux Sustainable Solutions pod was our eco motto, “Corrosion Solutions that don't cost the earth”, creating awareness of our environmentally friendly high performance, low VOC waterborne coating systems.
Environmental sustainability is a core element of the Dulux® Protective Coatings business philosophy, with the move away from solvents and towards water-based and higher solids alternatives. Achieving Ecologically Sustainable Design is top priority, but the issues regarding our environment and how our building designs can affect it, are complex.

St Ignatius College Chapel, SA
Aluminium is a great building material being lightweight with design flexibility. Unlike perforated or punched sheet steel, this perforated sheet aluminium does not suffer from edge corrosion as the metal is inherently corrosion resistant. This resistance offers design opportunities less suited to other sheet metals.
The Chapel of the Holy Name was built in the grounds of the beautiful St Ignatius College Senior School in Athelstone, South Australia. The design brief, according to the delightful story on the Australian Institute of Architects' website, www.architecture.com.au, called for a building which “embodies the symbolism of the great Catholic and Jesuit history and tradition”.
Project architects, DesignInc Adelaide, used the unique qualities of sheet aluminium to great advantage in their design of the Chapel.
Integral to this “iconically powerful” design is the use of repeating motifs of ancient Christian origin, computer-aided laser cut into aluminium sheet. The sheets were then prepared and primed with Dulux Luxepoxy® 4 White Primer, spray-painted with Dulux Quantum® FX featuring its metallic polyurethane finish with high sparkle. Quantum® Clear high gloss polyurethane clear coat was applied highlighting the metallic effects. Fixed to the building protecting the upper faceted glass wall, the panels wrap around the entire circumference of the Chapel, emphasising the “embracing space” aspired to by the Architects in their design.
The chosen colour is sympathetic to the red brick of the base and bell tower, which in turn echoes the colours of surrounding brick and sandstone buildings.
Dulux Protective Coatings congratulates the DesignInc Adelaide design team, the project builders, Marshall & Brougham Constructions, the St Ignatius College clients and the coating applicators, Dickson Glass & Aluminium, and our Dulux Representative, Malcolm Lunn of Adelaide, who provided expert technical advice and coating materials.

Too Cold To Paint
Epoxies and polyurethanes work by addition reaction chemistry. Simply, this means that two reactive components need to be combined in the correct proportions for reaction and hardening, achieving the coating's ultimate film properties. These reactions are highly dependent on an initial activation temperature. Generally our products are formulated to work best between 10°C and 30°C, based on the average temperature range in Australia. |

In some respects, two-pack coatings work similarly to human chemistry. We feel a bit sluggish and slow down when the temperature gets below 10°C and risk overheating beyond 30°C. Two-packs can react in the same way.
During winter, let's deal appropriately with cold conditions!
If the temperature gets below 5°C we chill, and so will a general epoxy unless it is specifically formulated. Called a B-phase, it means the full reaction hasn't occurred and the coating will either be sticky or cheesy (yes, these are conventional paint terms!). The reaction will stall, and is unlikely to recover due to the polymer having grown through partial reaction. The product is now too cumbersome and will inhibit further of Part A and B molecules.
Tip 1: If using standard products and hardeners, it's important that the substrate (steel, concrete etc) is above 10°C and 3°C above the dew point. If possible, heat the area with a portable heater until the surface temperature is at least 10°C.
Tip 2: The paint should be in the 15°C to 20°C range. If the paint can't be stored in warm conditions then warming the separate Part A and Part B components just prior to use can help in colder weather. Don't overdo it by going any higher than this temperature range. Don't warm the paint after you have mixed the two components, as you will cook the reaction and you will lose paint through a shortened pot-life, compromise adhesion and possibly ruin expensive spraying equipment.
Tip 3: Regardless of season, it is critical to mix the two components (Part A and Part B) with a power-driven mixer. Mix for 3 minutes, scraping bottom and sides of the container. In winter, careful mixing is more critical as power mixing breaks up the structure of viscous and high solids paints additionally putting energy into the molecules that will feed them energy to initiate a reaction with their mates.
Tip 4: Choose products specifically formulated for low temperature cure. Dulux Protective Coatings has a range of products with cold cure hardeners listed below.
Dulux Winter Cure Products
Dulux® Protective Coatings now offers you an extended range of products with low temperature hardeners to help you keep working during the winter months.
Duremax® GPE, Durebild® STE, Weathermax® HBR and Luxathane® R are available in AS2700 and Dulux Colour Specifier colours.

Tech Note - Metallic Coatings
Metallic pigmented coatings (or metallic finishes) are coatings that contain irregular, flat, reflective pigments. These pigments may be aluminium flake, micaceous iron oxide or mica. Reflecting light, the flat pigments add a characteristic “metallic” look to the coating, varying from a bright glitter to a dull sheen. The variation in “sparkle” depends on the particle size – the larger the particle size, the better the light reflection and the greater the sparkle.
Metallic finishes exhibit a phenomenon called “flip” – that is, the perceived colour varies depending on viewing angle. A metallic finish sample viewed at an angle where it picks up maximum light, will appear quite light, whereas the same sample viewed is reduced lighting will appear as a much darker colour shade.
How does millscale cause corrosion? Millscale is less reactive (more “noble”) than the steel underneath, and consistent with the behaviour of two dissimilar metals when in contact, the less noble metal will corrode at the expense of the more noble metal. The image clearly shows bluish millscale flaking off the rusted steel underneath under the protective coating.
