Expansion of Applications for High Heat-Reflective Coatings - November 20, 2001

### **What is High Heat-Reflective Coating?**
High heat-reflective coatings are applied to the exterior walls and roofs of buildings to enhance the reflection of sunlight and prevent heat from penetrating into the building. These coatings reflect near-infrared rays in sunlight, reducing the surface temperature of the building. This helps to suppress the rise in indoor temperature, reducing the amount of energy required for cooling. The energy-saving effect is particularly high during the summer when cooling loads are reduced.

### **Expansion of Applications and Background**
With the enforcement of the revised Energy Conservation Law, the demand for high heat-reflective coatings as an energy-saving measure has increased. These coatings are now widely used not only in residential buildings but also in commercial facilities, factories, warehouses, and other large buildings. Additionally, as energy-saving standards for public facilities and schools become stricter, these coatings are gaining attention as a means to improve the overall energy efficiency of buildings.

Moreover, while high heat-reflective coatings were primarily used in new constructions, there has been an increase in their use for the renovation and refurbishment of existing buildings. This allows for the enhancement of insulation performance in older buildings, thereby contributing to a reduction in environmental impact.

### **Technical Features and Effects**
High heat-reflective coatings offer the following technical features and effects:

1. **High Reflectivity**: The special pigments in the coating reflect sunlight, suppressing the rise in the surface temperature of the building.
2. **Durability**: The coatings are resistant to UV rays and weathering, maintaining their effectiveness over a long period.
3. **Environmental Compatibility**: Products that do not contain or have low levels of volatile organic compounds (VOCs) have been developed, reducing environmental impact.
4. **Color Variety**: A wide range of colors is available, allowing for functionality without compromising aesthetics.

### **Market Impact and Future Outlook**
The market for high heat-reflective coatings is expected to continue expanding as building energy efficiency standards become increasingly stringent. Furthermore, these coatings are often eligible for energy-saving subsidies from local governments, which is expected to further promote their adoption.

In summary, the expansion of applications for high heat-reflective coatings greatly contributes to promoting energy savings and reducing environmental impact, making it a technology of significant interest for the future.
