What does the gloss value represent?
Among the hot topics on the Internet in the past 10 days, "gloss value" has become a high-frequency keyword in discussions about material science, industrial manufacturing and consumer product quality. Glossiness, as an indicator of the ability of an object surface to reflect light, is widely used in coatings, plastics, metals, ceramics and other industries. This article will combine structured data to analyze the meaning of gloss values and their practical applications.
1. Definition and measurement principle of gloss
Glossiness refers to the ability of an object's surface to reflect light. The higher the value, the smoother the surface and the stronger the reflection. International standards (such as ISO 2813, ASTM D523) stipulate the use of 60° angle measurement as a general method, and some scenes will supplement 20° (high gloss) or 85° (low gloss) data.
| gloss range | surface features | Typical applications |
|---|---|---|
| 0-10GU | matte/matte | Architectural coatings, frosted glass |
| 10-70GU | Semi-gloss | Furniture, woodware, car interiors |
| 70-100GU | high gloss | Piano paint, electronic product casing |
| 100+GU | mirror effect | Metal coating, optical devices |
2. Comparison of application data in popular industries
According to recent industry reports, gloss requirements vary significantly in different fields:
| Industry | Average gloss (60°) | Trend changes in 2024 |
|---|---|---|
| New energy vehicle coatings | 85-95GU | +3.2% (pursuing high reflective texture) |
| High-end home appliance panel | 60-75GU | -5% (switch to anti-fingerprint matte) |
| 3D printed products | 30-50GU | +8% (post-processing technology improvement) |
3. Analysis of consumer hot spots
Social media data in the past 10 days shows:
4. Technology Frontier Trends
Latest research breakthroughs include:
| Technical name | Glossiness improvement | R&D institutions |
|---|---|---|
| Nanoscale self-cleaning coating | Maintain 95 GU (5-year decay <3%) | Ningbo Institute of Materials Science, Chinese Academy of Sciences |
| AI assisted spraying system | Batch variation reduced from ±5 GU to ±1 GU | Fraunhofer Institute, Germany |
5. Purchase suggestions and precautions
1.Match usage scenarios: High gloss and easy to show scratches. It is recommended to choose outdoor products below 50 GU.
2.View test report: Regular products will indicate the measurement angle and standard (such as ISO 2813)
3.Pay attention to the impact of ambient light: The visual difference in glossiness of the same object at 3000K and 6500K color temperatures can reach 15%
From the above structured data analysis, it can be seen that the gloss value is not only a technical parameter, but also directly affects the aesthetics and service life of the product. With the popularization of testing technology (the price of portable gloss meters has dropped to the thousand yuan level), consumers are gaining more rights to know, which also forces manufacturers to more strictly control surface treatment processes.
