Arccoil EX 710 Liquid Coating for Architectural Aluminium Extrusions
A spray-applied liquid coating for aluminium window, door, shopfront and curtain wall profiles, supplied on a polyester binder for general architectural work or on a 70:30 PVDF and acrylic binder where the profile must match the coil coated sheet on the same building. It is applied over a chromate-free conversion coating and a matched primer, then oven cured.

1. Product description
A spray-applied liquid coating for window, door, shopfront and curtain wall profiles, supplied on a polyester binder for general architectural work and on a 70:30 PVDF and acrylic binder where the specification matches the coil coated sheet on the same building. It is applied over a chromate-free conversion coating and a matched primer, then oven cured to the metal temperature the binder needs. It exists to serve applicators running a liquid spray line and oven, where powder is not the specified route.
2. Features
- Polyester binder for general architectural work
- 70:30 PVDF and acrylic binder to match coil coated sheet on the same building
- Applied over a chromate-free conversion coating and a matched primer
- Sprayed wet on wet or with an intermediate flash off
- For applicators running a liquid spray line and oven where powder is not the specified route
3. Recommended uses
Architectural aluminium extrusions for windows, doors, shopfronts and curtain wall. Colour continuity with coil coated sheet is agreed on approved panels before production, because the two routes lay down different films.
Substrates. Architectural aluminium extrusions, cleaned, etched and chromate-free conversion coated, then primed.
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Solvent-borne polyester, or 70:30 polyvinylidene fluoride and acrylic, liquid spray system | Formulation |
| Supply viscosity | Supplied at the viscosity agreed for the spray equipment and stated on the Certificate of Analysis | ISO 2431 flow cup, or customer or supplier protocol |

| Cure, metal temperature and hold | Polyester binder about 180 to 200 degrees Celsius for 10 to 20 minutes; PVDF binder about 230 to 245 degrees Celsius for around 10 minutes | Customer or supplier protocol, metal temperature logged on the profile |
| Specular gloss, 60 degrees | Set to the specification: polyester binder within 30 to 80 gloss units, PVDF binder within 25 to 40 | ISO 2813, ASTM D523 |
| Colour difference against the approved panel | Delta E commonly specified at not more than 1.0 for solid colours; continuity with coil coated sheet agreed on approved panels | ASTM D2244 |
| Cross-cut adhesion | Classification 0, no removal at the cut edges or intersections | ISO 2409 |
| Pencil hardness | Polyester binder F to 2H; PVDF binder HB to F | ASTM D3363 |
| Solvent resistance, methyl ethyl ketone double rubs | 50 to 100 double rubs without exposure of the primer, used as a cure check | ASTM D5402 |
| Neutral salt spray resistance, finished system | 500 to 1000 hours with creep from the scribe not more than 2 mm and no field blistering, set by the system chemistry and film build | ISO 9227, ASTM B117 |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Spray application on a liquid spray line with an oven, wet on wet or with an intermediate flash off |
| Surface preparation | Extrusions cleaned, etched and chromate-free conversion coated, then primed with the matched primer |
| Viscosity adjustment | Correct with the supplied thinner only, to the supplied ratio |
| Applied film | Primer 5 to 10 microns and topcoat 20 to 30 microns dry |
| Cure, polyester binder | Metal temperature of about 180 to 200 degrees Celsius held for 10 to 20 minutes |
| Cure, PVDF binder | Metal temperature of about 230 to 245 degrees Celsius held for around 10 minutes |
| Alloy and temper | Confirm the bake with the extruder against the alloy and temper, because a long bake at fluoropolymer cure temperature can soften a 6000 series temper |
Process. Primer at five to ten microns and topcoat at twenty to thirty microns dry, sprayed wet on wet or with an intermediate flash off, then oven cured. The polyester binder cures at a metal temperature of about 180 to 200 degrees Celsius held for ten to twenty minutes; the PVDF binder needs about 230 to 245 degrees Celsius metal temperature held for around ten minutes. Confirm the bake with the extruder against the alloy and temper, because a long bake at fluoropolymer cure temperature can soften a 6000 series temper.
6. Storage and handling
Store in the original, tightly closed containers in a cool, dry, covered area away from direct sunlight and heat, and stir to a uniform consistency before use. Shelf life is stated on the label and Certificate of Analysis. Handle and use the product in line with its Safety Data Sheet.
7. Safety and regulatory information
Read the Safety Data Sheet before use. Safety Data Sheets and regulatory declarations are issued by our technical centre against the product and batch supplied, so they are sent on request rather than published. Request a Safety Data Sheet or declaration.
