Arcprime WB 110 White Basecoat for Film and Metal
An opaque white basecoat that puts a printable white ground on a substrate that is not white, so that a CMYK digital image reproduces to the intended colour. It is pigmented for opacity at a practical coat weight and finished so that the digital process can image directly onto it without a further primer.

1. Product description
An opaque white basecoat that puts a printable white ground on a substrate that is not white, so that a CMYK digital image reproduces to the intended colour instead of being shifted by the substrate beneath it. It is pigmented for opacity at a practical coat weight and finished so that the digital process can image directly onto it without a further primer. It is the highest film build product in the Arcprime range and the highest in non-volatile content.
2. Features
- Opaque white ground so that the digital image is not shifted in colour by the substrate
- Pigmented for opacity at a practical coat weight
- Surface finished so that the digital process can image directly onto it
- Heavier film build than the other Arcprime grades, at 4 to 12 g/m², and higher non-volatile content than the water-based grades, at 45 to 60 per cent by weight
- Hot-air dried on film and stoved on metal
3. Recommended uses
White grounding of clear and metallised PET, BOPP and PE film, aluminium foil and foil laminates, tinplate and aluminium sheet, and coloured synthetic stocks ahead of digital printing. Typical work includes digitally printed flexible packaging, labels and decorated metal where the substrate is clear, metallic or coloured.
Substrates. Clear and metallised PET, BOPP and PE film, aluminium foil and foil laminates, tinplate and aluminium sheet, and coloured synthetic stocks.
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Opaque white pigmented basecoat, hot-air dried on film and stoved on metal | Formulation |
| Appearance | Opaque white liquid, drying to an opaque white film | Visual |
| Non-volatile matter | 45 to 60 per cent by weight | ISO 3251 |
| Supply viscosity | Set to the coating method, gravure or roller coater, and confirmed on the Certificate of Analysis for the batch supplied | ISO 2431 flow cup or ISO 3219-2 rotational viscometer, as appropriate to the grade supplied |
| Density at 23 °C | 1.30 to 1.65 g/cm³ | ISO 2811-1, pycnometer |
| Applied dry coat weight | 4 to 12 g/m² in total, in one or two passes | ISO 2808, gravimetric determination |
| Contrast ratio at a fixed spreading rate | 0.88 to 0.96 at the fixed spreading rate of the test | ISO 6504-3 |
| Wetting tension of the white surface | 38 to 46 mN/m | Test inks to ISO 8296; surface free energy, where required, by contact angle to ASTM D7490 |
| Adhesion of the digital image over the basecoat, on film and metal | Cross-cut classification 0 to 1 on metal sheet and where the blade can cut the coating without cutting through the base; on thin film and foil, judged by tape pull on the printed area against a retained reference | ISO 2409; tape pull to ASTM F2252/F2252M on thin film and foil |
| Block resistance, 30 min at 50 °C under the specified load | Rating 8 to 10 | ASTM D4946 |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Gravure or roller coater for film; roller coater for sheet and coil metal; offline |
| Surface preparation | Corona or flame treat film immediately before coating and check wetting tension with test inks; foil free of rolling oil; aluminium sheet and coil cleaned and conversion pretreated as for coil coating; tinplate coated as supplied with its standard mill passivation and lubricant film |
| Dilution | Supplied ready for use. Adjust only with the diluent and within the limit stated on the confirmed Technical Data Sheet |
| Applied dry coat weight | 4 to 12 g/m² in total; two passes are normal where a high contrast ratio is required |
| Drying or stoving | Hot air on film; on metal, stoving in an oven to the peak metal temperature confirmed for the grade supplied |
| Next step | Cool fully before the digital image, or a primer where the trial calls for one, goes on top |
Process. Gravure or roller coater for film, roller coater for sheet and coil metal. Offline. Two passes are normal where a high contrast ratio is required. Hot-air drying on film, and stoving to a defined peak metal temperature in an oven on metal.
6. Storage and handling
Store in the closed original container at ambient temperature, clear of frost and direct sunlight. Shelf life is stated on the label and Certificate of Analysis, and handling information is given in the Safety Data Sheet, issued on request. 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.
