Arcplast UV 310 UV-Curable Hardcoat Clear
A single-component UV-curable acrylate hardcoat for transparent and decorated plastic parts on high throughput lines. It crosslinks in seconds under a mercury or LED source, so parts can be handled, inspected and packed immediately instead of occupying oven and rack space.

1. Product description
A single-component UV-curable acrylate hardcoat for transparent and decorated plastic parts on high throughput lines. It crosslinks in seconds under a mercury or LED source, so parts can be handled, inspected and packed immediately instead of occupying oven and rack space. UV 310 is the standard build grade for scratch protection over printed, metallised and pigmented surfaces.
2. Features
- Crosslinks in seconds under UV with no bake or rack hold; solvent thinned versions need a short heated flash first
- Photoinitiator package specified for the source in use, mercury or LED
- Standard build of 10 to 15 microns for scratch protection
- Applied over printed, metallised and pigmented surfaces
- Spray, flow coat, dip or roller application
3. Recommended uses
Protective clear over printed, metallised and pigmented plastic parts and over transparent polycarbonate, PMMA, ABS, PET and PETG parts, where scratch protection is needed at line speed.
Substrates. Polycarbonate, PMMA, ABS, PET and PETG, primed polyolefin, and decorated or metallised layers needing a protective clear.
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Single-component UV-curable acrylate, supplied solvent free or solvent thinned | Formulation |
| Appearance | Clear liquid | Visual |
| Non-volatile content | Solvent thinned versions 30 to 60 per cent by weight; solvent free versions carry no added solvent | ASTM D5403, Test Method B, on solvent thinned versions; non-volatile content by difference |
| Flow time at 23 degrees C, spray versions | 30 to 50 s, ISO 4 mm cup; flow coat, dip and roller versions supplied at the viscosity agreed for the line | ISO 2431 |
| Dry film thickness | 10 to 15 microns | ISO 2808 |
| UV cure | At the UV dose and peak irradiance issued by Arctic for the grade and the source in use, mercury or LED, with belt speed set against in-line radiometry | Radiometer travelling the belt at production speed; customer or supplier protocol |
| Specular gloss at 20 degrees | 85 GU and above, screened at 60 degrees | ISO 2813 |
| Pencil hardness | H to 2H | ASTM D3363 |
| Taber abrasion, haze increase, CS-10F wheels, 500 g | Under 5 per cent haze gain at 100 cycles on transparent substrates | ASTM D1044, haze measured to ASTM D1003 |
| Cross-cut adhesion | Class 0 to class 1, before and after humidity exposure | ISO 2409, 2 mm cut spacing on plastic substrates |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Spray, flow coat or dip; roller on flat parts |
| Surface preparation | Clean, dust free and free of release agents; polyolefin primed. On polycarbonate and ABS, solvent balance and flash are set against stress cracking |
| Applied film thickness | 10 to 15 microns |
| Flash | Solvent thinned versions flash 3 to 5 minutes at 50 to 60 degrees C before cure, since retained solvent leaves a soft film after cure |
| Cure | UV, mercury or LED as specified for the photoinitiator package, at the UV dose and peak irradiance issued by Arctic for the grade and the source in use; a change of source is re-qualified rather than the belt speed copied across |
| After cure | Parts can be handled, inspected and packed immediately after cure |
Process. Spray, flow coat or dip applied at 10 to 15 microns, or roller applied on flat parts. Solvent thinned versions flash 3 to 5 minutes at 50 to 60 degrees C before cure, since retained solvent leaves a soft film after cure. Cured under UV at the dose stated for the source in use, with belt speed set against in-line radiometry rather than by lamp hours. The photoinitiator package is specified for the source, mercury or LED, because the two do not emit the same spectrum.
6. Storage and handling
Store in the original closed, opaque containers away from sunlight and other UV sources, direct heat and frost, and keep lids closed between uses. Shelf life is stated on the label and Certificate of Analysis; refer to the Safety Data Sheet, issued on request, for handling. 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.
This Technical Data Sheet is published for on-screen reference. The information is given in good faith from laboratory and application experience and describes typical values; it is not a specification and does not replace a trial on your own substrate and line.
