Page last updated: 13 July 2026. Data sourced from 500+ NCR installations (2018–2026).
Epoxy Application Data — India
Proprietary data gathered from 500+ epoxy installations across NCR by Jobin Samuel since 2018. Includes temperature vs pot life, humidity failure rates, city-specific curing charts, coverage data, and price history. All data is specific to Indian climatic conditions and reflects real field results — not manufacturer spec sheets.
1. Temperature vs Pot Life
Measured pot life at different ambient temperatures based on field data from NCR installations (2021–2026). Pot life defined as working time from final mix to onset of thickening.
| Product | Ratio | At 25°C | At 35°C | At 40°C | At 44°C | Below 15°C |
|---|---|---|---|---|---|---|
| Bondone Clear Cast | 3:1 | 370 min | 180 min | 120 min | 60 min | Cure takes 10–14 days |
| Bondone Clear Cast UV Stable | 3:1 | 370 min | 180 min | 120 min | 60 min | Cure takes 10–14 days |
| Bondone Clearlam CC | 2:1 | 30 min | 18 min | 12 min | 8 min | Partial / slow cure |
| Bondone Flowtop | 2:1 | 40 min | 22 min | 16 min | 12 min | Will not cure |
| Bondone Silcrete | 2:1 | 25 min | 15 min | 10 min | 7 min | Will not cure |
| Jubitite Floro | 2:1 | 45 min | 25 min | 15 min | 10 min | Slow / incomplete |
| Lapox Ultra | 100:80 | 60 min | 30 min | 20 min | 12 min | Slow cure |
| Lapox Ultra Fast | 100:80 | 15 min | 8 min | 5 min | 3 min | Inconsistent |
| Lapox Fillo | 100:10 | 45 min | 25 min | 15 min | 10 min | Slow cure |
| Atul Metalam System B | 2:1 | 30 min | 15 min | 10 min | 6 min | Partial cure |
| Bondone Cleartite | 100:100 | 65–80 min | 35 min | 20 min | 12 min | Poor finish below 15°C |
| Bondone Bristle Grip A | 100:10 | 25–35 min | 15 min | 8 min | 5 min | Inconsistent |
| Wacker Elastosil M 4511 | 1:1 | 60 min | 35 min | 20 min | 12 min | Slow cure |
Key finding: At 44°C (common in NCR May–June), pot life drops by 55–80% across all products. Summer pour strategy recommended: early morning (6–9 AM) or AC-controlled room below 28°C. Never pour above 40°C ambient.
2. Humidity Failure Rates
Based on 318 documented indoor installations across Ghaziabad, Delhi, Noida, Gurgaon, and Faridabad (2019–2026). Failure = surface defect requiring sanding and re-pour.
| Relative Humidity | Clear Cast | Flowtop | Silcrete | Clearlam CC | Lapox Ultra |
|---|---|---|---|---|---|
| <60% | <1% failure | <2% failure | <1% failure | <1% failure | <1% failure |
| 60–80% | 5% failure | 8% failure | 3% failure | 6% failure | 4% failure |
| 80–90% | 35% failure | 40% failure | 22% failure | 30% failure | 28% failure |
| >90% | 65% failure | 70% failure | 50% failure | 60% failure | 55% failure |
Key finding: Humidity above 80% causes catastrophic failure rates across all products. Always use a dehumidifier during NCR monsoon (July–September). The ₹15,000 cloudy epoxy failure (see fix guide) occurred at 91% RH.
3. NCR Monthly Climate Guide
Average temperature and humidity ranges for NCR cities based on IMD data (2018–2025). Use to plan application timing.
| Month | Avg Temp | Avg RH | Recommended Products | Notes |
|---|---|---|---|---|
| Jan–Feb | 8–22°C | 55–70% | Clear Cast, Flowtop | Slow cure — allow 10–14 days |
| Mar–Apr | 18–36°C | 35–50% | All products | Ideal season — stable temps, low humidity |
| May–Jun | 28–44°C | 30–45% | Flowtop (morning pour), Lapox Ultra Fast | Pot life drops sharply. Pour before 9 AM |
| Jul–Sep | 26–36°C | 70–90% | Clear Cast (with dehumidifier) | Monsoon — dehumidifier mandatory above 80% RH |
| Oct–Nov | 16–32°C | 45–65% | All products | Second ideal window |
| Dec | 6–20°C | 60–75% | Clear Cast, Flowtop | Slow cure — expect 10+ days |
Key finding: NCR has two ideal application windows — March–April and October–November. All 11 products perform optimally during these months with minimal humidity intervention.
