Accurate Mixing Ratios (Temperature Dependent)
Base Coat Ratios:
- 5–10°C: 4% (1kg per 25kg resin)
- 11–17°C: 3% (1kg per 33kg resin)
- 18–25°C: 2% (1kg per 50kg resin)
- 26–30°C: 1% (1kg per 100kg resin)
Top Coat Ratios:
- 5–17°C: 3% (1kg per 33kg topcoat)
- 18–25°C: 2% (1kg per 50kg topcoat)
- 26–30°C: 1% (1kg per 100kg topcoat)
📌 Conversion Guide:
