Case Study: Application of Ganzkuhl PDRC Coating on a Vehicle.

ByQgen Team

Introduction

In urban environments with intense sunlight, vehicles often experience extreme heating, leading to uncomfortable interiors and increased energy consumption for air conditioning. This case study examines the application of Ganzkuhl® PDRC Coating on a standard passenger car.

Q Gen-Next Sustainable Technology Pvt. Ltd., the innovator behind Ganzkuhl®, focuses on eco friendly solutions to combat heat and promote sustainability. Ganzkuhl® PDRC Coating is a ceramic-based Passive Daylight Radiative Cooling product that reflects up to 98.6% of solar heat, emits thermal radiation effectively, and provides waterproofing, making it suitable for automotive applications.

Need for Coating

Vehicles parked or driven in hot climates, such as those in tropical or desert regions, absorb significant solar heat through their metal bodies and roofs. This results in surface temperatures exceeding 60°C, causing interior heat buildup, discomfort for passengers, and higher fuel or battery consumption due to prolonged air conditioning use. The car owner in the demonstration sought a sustainable, passive cooling solution to mitigate these issues without relying on energy intensive systems. Ganzkuhl® PDRC Coating was chosen for its proven reflectivity and cooling properties, as evidenced in the video test on a car exposed to direct sunlight.

Pre-Coating Temperature Readings

Before applying the coating, temperature measurements were taken on the car’s roof and body under peak summer sunlight conditions. The uncoated metal surfaces reached 62-65°C, contributing to an interior cabin temperature of 50-55°C. This heat absorption created an uncomfortable environment and increased the load on the vehicle’s AC system.

Coating Application

Ganzkuhl® Premium Grade was selected for the vehicle. The car’s surface was cleaned thoroughly using high-pressure water jetting to remove dirt, oil, and contaminants. Two coats of Ganzkuhl® Base Coat were applied via brushing or spraying, followed by a single Top Coat once the base had dried. The process followed manufacturer guidelines, and the coated surfaces were allowed to cure for 24-48 hours in sunlight for optimal adhesion and performance. The application was straightforward, suitable for automotive exteriors like roofs, hoods, and sides.

Post-Coating Temperature Readings

Post-curing, measurements were conducted under similar sunny conditions, as shown in the YouTube demonstration. The coated surfaces exhibited a dramatic drop to 38.2°C—a reduction of approximately 17°C. Interior cabin temperatures also decreased, improving comfort and reducing AC dependency. This performance aligns with PDRC principles, where high solar reflectance and thermal emissivity enable passive cooling, even on mobile surfaces like vehicles.

Conclusion

The Ganzkuhl® PDRC Coating application on the car, as featured in the YouTube video, effectively lowered surface and interior temperatures, transforming a heat-trapping vehicle into a cooler, more efficient one. The 17°C reduction enhanced passenger comfort, cut energy use for cooling, and extended the lifespan of interior materials by minimizing heat damage. This demonstration highlights Ganzkuhl®’s versatility beyond static structures, offering a sustainable solution for automotive heat management and contributing to reduced carbon emissions from vehicle AC systems.
