To improve the outdoor anti-aging performance of PC Hollow Sheets, the technical R&D team has overcome technical difficulties in anti-aging UV coating and realized a maximum UV coating thickness of 90 microns.
UV coating can effectively block ultraviolet rays, slow down yellowing and aging, and extend the service life of PC Hollow Sheets. The thickness of UV coating and its uniformity are core indicators for judging PC Hollow Sheet quality. UV coating cannot be observed by naked eyes and can only be detected by an electron microscope. Free sample testing service is available.
1. Core UV Coating Technical Data
1.1 Service Life Comparison of Different UV Coating Thicknesses
| UV Coating Thickness | Theoretical Outdoor Service Life |
|---|---|
| 50 μm | 10 years |
| 90 μm | 15 years |
1.2 Correlation Between Sheet Areal Weight and Maximum UV Coating Thickness
| PC Hollow Sheet Areal Weight | Peak UV Coating Thickness |
|---|---|
| 1 kg/㎡ | 73 μm |
| 1.2 kg/㎡ / 1.3 kg/㎡ | 90 μm |
1.3 Optional UV Coating Specifications for Engineering Projects
Available UV coating thickness options: 50 μm, 60 μm, 70 μm, 80 μm, 90 μm.
Uniform thickness test results: After measurement with micrometers on the surface layer, vertical ribs and bottom layer of finished PC Hollow Sheets, both the overall sheet thickness and UV coating layer are uniform.
