Abstract
This 14-month longitudinal study comprehensively analyzes antimicrobial coating durability across Singapore's distinct seasonal patterns, including both monsoon seasons and inter-monsoon periods. Testing was conducted on 200 surfaces across 50 diverse locations, with continuous environmental monitoring to correlate coating performance with climate conditions.
Results demonstrate consistent 97%+ antimicrobial efficacy regardless of humidity fluctuations between 65-95% RH, temperature variations from 24-35°C, and exposure to monsoon conditions.
Results
"97%+ efficacy maintained year-round regardless of humidity fluctuations from 65-95% RH"— Seasonal Durability Finding
| Season | Period | Avg Humidity | Avg Efficacy |
|---|---|---|---|
| Northeast Monsoon | Nov-Mar | 86% RH | 97.4% |
| First Inter-Monsoon | Apr-May | 84% RH | 97.8% |
| Southwest Monsoon | Jun-Sep | 83% RH | 97.6% |
| Second Inter-Monsoon | Oct-Nov | 85% RH | 97.3% |
Performance by Environment Type
- Air-conditioned indoor: 98.2% average efficacy
- Naturally ventilated: 97.5% average efficacy
- Semi-outdoor: 97.1% average efficacy
- Outdoor sheltered: 96.8% average efficacy
Conclusion
Key Takeaways
- 97%+ efficacy maintained across all Singapore seasonal periods
- No significant correlation between climate conditions and coating performance
- Minimal variation between indoor (98.2%) and outdoor (96.8%) environments
- Annual reapplication schedule supported by 14-month durability data
