Arcterra CM 510 Cab and Panel Finish
A two-pack aliphatic acrylic polyurethane finish on a short schedule for cab shells, doors, panels, mudguards, steps and small parts sprayed on jigs or racks. It is handleable quickly at ambient and reaches full properties under a moderate force dry, with colour and sheen matched to the Arcterra PU topcoat on the machine.

1. Product description
A two-pack aliphatic acrylic polyurethane finish on a short schedule for cab shells, doors, panels, mudguards, steps and small parts sprayed on jigs or racks away from the main fabrication line. It is formulated to be handleable quickly at ambient and to reach full properties under a moderate force dry, so a jig line can be turned round within a shift without a high bake. Colour and sheen are matched to the Arcterra PU topcoat on the machine, so a cab built on a separate route arrives in the same colour as the chassis it is fitted to.
2. Features
- Short schedule for jig and rack lines within a shift
- Force dry at 60 to 80 °C for 20 to 40 min, no high bake
- Colour and sheen matched to the Arcterra PU topcoat
- Suited to conventional air, HVLP or electrostatic spray
3. Recommended uses
Cabs, doors, panels, mudguards, steps and small parts painted on a separate route from the main fabrication line, so that they arrive in the same colour as the chassis they are fitted to.
Substrates. Arcterra EP 210 primed steel, phosphated or otherwise pretreated sheet, and abraded sound existing coatings on bought-in components.
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Solvent-borne two-pack aliphatic acrylic polyurethane with aliphatic isocyanate hardener | Formulation |
| Colour | Matched to the Arcterra PU topcoat on the machine; agreed on a sprayed panel at production gloss | ISO 3668 visual comparison; instrumental to ISO/CIE 11664-4 where agreed |
| Specular gloss at 60° | Matched to the machine topcoat: high gloss 85 GU and above, or satin 30 to 50 GU | ISO 2813 |
| Dry film thickness | 40 to 70 µm | ISO 2808 |
| Pot life of mixed material at 25 °C | Typically 2 to 6 h, shortening sharply as temperature rises | ISO 9514 |
| Drying and cure | Through-dry in 16 to 24 h at 20 to 25 °C, full properties in 5 to 7 days; force dry at 60 to 80 °C for 20 to 40 min | ISO 9117-1 for through-dry; full properties and force-dry schedule to customer or supplier protocol |
| Cross-cut adhesion | Class 0 to 1 on prepared steel and between coats within the recoat interval | ISO 2409 |
| Accelerated weathering, gloss retention | Typically specified to retain 60 per cent or more of initial gloss after 1000 h xenon arc exposure | ISO 16474-2 for exposure, ISO 2813 for gloss, ISO 4628-6 for chalking |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Method | Conventional air, HVLP or electrostatic spray on jigs or racks; substrate held at least 3 °C above dew point through application and flash-off |
| Substrate | Arcterra EP 210 primed steel, phosphated or otherwise pretreated sheet, and abraded sound existing coatings on bought-in components |
| Mixing and thinning | Base and hardener mixed in the ratio stated on the label and stirred mechanically before use. Thin only where needed and only with the thinner specified by Arctic for the grade. For electrostatic application, the resistivity of the mixed material is adjusted into the range required by the equipment, using only the thinner specified by Arctic for the grade. |
| Applied film | 40 to 70 µm dry |
| Cure | Ambient at 20 to 25 °C, or force dry at 60 to 80 °C for 20 to 40 min after an ambient flash-off, with the time counted once the part is at temperature; heavy plate sections take longer to reach it than the bay air |
| Colour approval | Colour match agreed on a sprayed panel at production gloss before the first batch |
| Safety | Handling and personal protection as set out in the Safety Data Sheet, issued by Arctic on request. |
Process. Conventional air, HVLP or electrostatic spray at 40 to 70 µm dry. Ambient cure at 20 to 25 °C or force dry at 60 to 80 °C for 20 to 40 minutes. Colour match agreed on a sprayed panel at production gloss before the first batch.
6. Storage and handling
Store base and hardener in their original, tightly closed containers in a cool, dry, covered store away from direct heat and sunlight, within the temperature range on the label, and keep hardener containers sealed against moisture. Shelf life is stated on the label and the 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.
