The data behind the grade.
Every model we sell has a technical data sheet with the numbers that decide whether it passes inspection — not a marketing page with a range and a logo.
Why this page exists
Most suppliers publish a catalogue. Buyers need a data sheet.
In a survey of 29 competitor sites in this industry, fewer than one in ten published a technical data sheet at all. The rest publish a brochure with a brightness number and a warranty length. That is enough to place an order and not enough to defend one in an inspection.
Measured values, not "up to". Where a figure is a minimum, it says so.
Each sheet states the test geometry — an RA number without 0.2°/−4° attached is not comparable.
Service temperature, adhesive type and liner release are listed because they cause most field failures.
Every sheet carries an issue date and a revision number, so a tender can reference a specific version.

Data sheet index
Ten models, one table, comparable numbers.
Sorted by grade. Every value here appears identically on the PDF, so a quotation can reference either.
| Model | Grade / standard | White RA | mm | Adhesive | °C | Warranty | TDS |
|---|---|---|---|---|---|---|---|
| NVR-1000 | Type I | 70 | 0.13 | Solvent acrylic | −30 / +70 | 5 | |
| NVR-2000 | Type II | 140 | 0.14 | Solvent acrylic | −30 / +70 | 7 | |
| NVR-4200 | Type IV | 360 | 0.18 | Solvent acrylic | −30 / +80 | 10 | |
| NVR-8000 | Type VIII | 700 | 0.20 | Solvent acrylic | −30 / +80 | 12 | |
| NVR-11000 | Type XI | 1,000 | 0.22 | Solvent acrylic | −30 / +80 | 12 | |

Photoluminescent and traffic-safety models (NVR-PL9, NVR-PL45, NVR-PL30, NVR-PLSN, NVR-SRS6, NVR-RS4, NVR-DP90, NVR-CN70, NVR-WL5) carry separate sheets with luminance decay and impact data — see the document library.
Optical behaviour
A reflective film is not a light source. It is a mirror with a narrow cone.
Retroreflection depends on two angles, and most catalogue numbers quietly assume the best one.
Effect of entrance angle
White RA, 0.2° observation| Entrance | NVR-1000 | NVR-4200 | NVR-8000 | NVR-11000 |
|---|---|---|---|---|
| −4° | 70 | 360 | 700 | 1,000 |
| 15° | 52 | 285 | 600 | 860 |
| 30° | 30 | 150 | 380 | 500 |
| 40° | 15 | 70 | 220 | 300 |
| 45° | 10 | 45 | 150 | 200 |
Glass-bead film loses 85% of its brightness by 45° entrance. Prismatic film loses 70–80%. This is the number that decides whether a sign works for a driver 200 m away or only for one directly underneath it.
Effect of observation angle
% of the 0.2° value retained| Observation | NVR-1000 | NVR-4200 | NVR-8000 | NVR-11000 |
|---|---|---|---|---|
| 0.2° | 100% | 100% | 100% | 100% |
| 0.33° | 96% | 98% | 99% | 100% |
| 1.0° | 61% | 72% | 88% | 94% |
| 1.5° | 42% | 55% | 78% | 88% |
Observation angle is set by the driver's eye height and the distance to the sign. A truck cab at 3.5 m and a car at 1.2 m do not see the same sign the same way — which is why a wider-angle grade earns its price on a freight corridor.
Field failures
What actually goes wrong, and why.
Compiled from 41 warranty investigations since 2019. The material was at fault in nine of them.
| Symptom | Mechanism | Prevention |
|---|---|---|
| Edge lifting within a week | Applied below 10 °C, so initial tack never developed. The film looked bonded and was not. | Substrate at 15 °C minimum, two passes with a 4 kg roller, 24 h before the sign goes up. |
| Hazy white patches | Residual solvent trapped because the oven was run above line speed. | Coating log tied to line speed; residual solvent held under 0.5% and checked per lot. |
| Night brightness fades in 18 months | Surface contamination plus water ingress at an unsealed edge on prismatic film. | Seal edges on Type VIII and above; wash interval specified in the installation sheet. |
| Print looks washed out after a year | General-purpose film printed with UV ink and no primer layer. | Use NVR-P3500, which carries an inline primer, or laminate. |
| Film cracks when unrolled in winter | Adhesive glass transition above the ambient temperature. | Low-temp adhesive variant, or condition the roll at 20 °C for 24 h before use. |
| Bubbles under the film | Dry application on a large panel with no air-release channel. | Wet application, or air-release liner. On 1.5 m panels there is no third option. |
| Uneven reflectivity across a roll | Bead settling in the coating pan between runs. | Bath agitation interval fixed at 20 min; RA checked at both ends of every roll. |
| Yellowing after three summers | Insufficient UV absorber in the top film. | 2,000 h xenon-arc before a formulation is released — not a 500 h screening test. |
Method equivalence
ASTM, EN and GB measure the same property three ways.
If you are comparing a Chinese quote with a European one, this is the table that explains the gap.
| Property | ASTM (US) | EN (EU) | GB (China) |
|---|---|---|---|
| Retroreflection | ASTM D4956-19 | EN 12899-1 | GB/T 18833-2012 |
| Observation angle | 0.2° / 0.33° / 1.0° | 0.33° (Class RA1/RA2) | 0.2° / 0.33° |
| Entrance angle | −4° / 30° | +5° / 30° | −4° / 15° / 30° |
| Colour | ASTM E1349, D65 | EN 12899-1 §5.2 | GB/T 18833 §5.3 |
| Adhesion | ASTM D903 | EN 12899-1 Annex D | GB/T 2792 |
| Weathering | ASTM G155, 2,000 h | EN 12899-1 §5.6 | GB/T 16422.2 |
| Impact | ASTM D2794 | EN 12899-1 §5.7 | — |
| Certificate type | Self-declaration + test report | Notified body DoP + CE mark | CCPC / CTA report |
The practical consequence
An ASTM D4956 report will not satisfy a European notified body, and a CE declaration of performance will not satisfy a US state DOT. The film can be identical. Budget for two reports — or ask us for the pair, which is cheaper than commissioning them separately.
