Vehicular Roof Coat - Conex Container Case Study
Container Pilot Objectives
•Objectives:
• Minimize Nanotech’s product coverage while maximizing performance
Minimizing product coverage will allow faster curing times
Minimizing product coverage will allow better pricing leverage
• Maximize performance is defined as
Minimum AC energy consumption
Prevent maximum solar energy ingress (RV coat and or Cool Roof)
Prevent conductive heat exchange from conductive surfaces (metal with insulator internally)
• Minimizing product coverage will allow for maximum container space internally and minimum added weight
Container Pilot Test Results

Key Takeaways
Energy Savings Potential:
• 70% maximum energy savings achieved with the combination of external reflective and internal low-emissive coatings. This demonstrates the synergy of reflective and emissive technologies in minimizing cooling loads.
• 45% energy savings with just the external coating.
Coating Thickness Impact:
• RV coating performance improves significantly with thicker Dry Film Thickness (DFT), making it suitable for applications that can accommodate additional coating layers.
• For thin DFT applications, the CR coating performs better due to its radiant properties, positioning it as the optimal choice for constrained environments.
Application Specificity:
• Note that while external coatings are effective, combining them with internal solutions (e.g., low-emissive coatings or aluminum thermal barriers) amplifies overall thermal performance.
• The internal bulk temperature differences during peak sun hours indicate the effectiveness of the coatings in mitigating solar heat ingress.
Operational Scenarios:
• Different performance under various scenarios, such as AC units set at 65°F versus 75°F will attract different potential end users and impact across different operational settings.
