Arctube OV 110 Flexible Gloss Overvarnish
Arctube OV 110 is a clear gloss overvarnish applied over dry offset decoration on aluminium tubes, monobloc cans and bottles. It protects the inks, sets the gloss level and gives the rub and scuff resistance the pack needs through filling, cartoning and use.

1. Product description
A clear gloss overvarnish applied over dry offset decoration on aluminium tubes, monobloc cans and bottles, to protect the inks, set the gloss level and give the rub and scuff resistance the pack needs through filling, cartoning and use. On tubes it is specified for flexibility, because the varnish is the outermost film when the tube is squeezed, rolled up and folded at the crimp. On monoblocs and bottles it has to take necking and give the slip the filling line needs. A varnish mismatched to the ink system, or cured short, loses intercoat adhesion, and a film too hard for a tube crazes at the crimp.
2. Features
- Clear gloss finish over dry offset inks
- Flexible through the crimp on tubes; takes necking and gives line slip on monoblocs and bottles
- Applied wet on wet with the inks or as a separate roller pass
- Thermally cured, or UV cured over UV-curing inks
3. Recommended uses
Finishing varnish for decorated aluminium tubes, monobloc aerosol cans and aluminium bottles, over Arctube BC basecoats and Arcdeco or other dry offset inks.
Substrates. Decorated aluminium tubes, monobloc aerosol cans and aluminium bottles, over Arctube BC basecoats and Arcdeco or other dry offset inks.
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Clear thermosetting overvarnish, with a UV-curing version for UV ink systems | Formulation |
| Appearance | Clear gloss film | Visual |
| Non-volatile content | 35 to 55 per cent by weight for thermally cured versions; 95 to 100 per cent for UV versions | ISO 3251 for thermally cured versions; ASTM D5403 for UV versions |
| Supply viscosity | 200 to 3,000 mPa.s at 25 degrees C, according to grade and application unit | Rotational viscometer at a stated shear rate, ISO 3219-2 |
| Dry film thickness | 3 to 8 micrometres | ISO 2808 |
| Specular gloss at 60 degrees | 75 to 95 GU | ISO 2813, on flat panels coated alongside the trial |
| Cure state, thermally cured versions | 50 to more than 100 methyl ethyl ketone double rubs without breakthrough, according to grade | ASTM D5402 |
| Adhesion | Cross-cut classification 0 to 1 on flat aluminium panels; no varnish or ink removal by tape on the decorated container | ISO 2409 on panels; EN 15421 on finished tubes; customer or supplier protocol on monoblocs and bottles |
| Flexibility | No cracking or loss of adhesion on the conical mandrel on coated aluminium panel | ISO 6860 |
| Slip, monoblocs and bottles | Coefficient of friction or slip angle within the limit agreed with the filler at qualification | Customer or supplier protocol |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Wet on wet over the inks from the varnish unit of the printer and cured with them, or a separate roller pass after the ink bake |
| Surface preparation | Decorated container over Arctube BC basecoat; ink system confirmed as compatible |
| Viscosity adjustment | Thermally cured versions set within 200 to 3,000 mPa.s at 25 degrees C for the roller unit, using only the thinner Arctic specifies for the grade; UV versions supplied at application viscosity and not thinned with solvent |
| Dry film thickness | 3 to 8 micrometres |
| Cure schedule | Typically 4 to 10 min at about 150 to 200 degrees C metal temperature, or by UV over UV-curing inks to a lamp dose agreed at trial; a short cure loses intercoat adhesion |
| Next step | Tubes to capping and, where specified, latex banding, then to the filler for filling and crimping; monoblocs and bottles to necking and shaping |
| Qualification | Compatibility with the inks confirmed in a trial on the customer's line |
Process. Applied wet on wet over the inks by the varnish unit of the printer and cured with them, or as a separate roller pass after the ink bake, typically 3 to 8 micrometres dry film, cured typically 4 to 10 min at about 150 to 200 degrees C metal temperature, or by UV over UV-curing inks. Compatibility with the inks is confirmed in a trial on the customer’s line.
6. Storage and handling
Store in the original, tightly closed containers in a cool, dry, covered area, protected from frost, direct sunlight and heat, and stir before use. Shelf life is stated on the label and Certificate of Analysis; handling guidance 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.
