Application Parameters:
- Density: Approximately 1.85
- Volume Solids: 52±3% (after mixing)
- Recommended Film Thickness: 80μm
- Theoretical Usage: 0.30kg/m²
- Actual Usage: Approximately 0.50kg/m² for spraying, approximately 0.40kg/m² for brushing
- Flash Point: ≥27°C
- Mixing Ratio: 10:1 (by weight)
- Drying Time:
- Air drying (23°C): Surface dry ≤ 30 minutes, full dry ≤ 24 hours, fully cured ≤ 7 days
- Oven drying (workpiece surface temperature 80±2°C): 60 minutes
- Recoat Interval:
- Minimum Interval: 12 hours (23°C)
- Maximum Interval: Unlimited, but zinc salts formed on the surface must be thoroughly removed before recoating to avoid compromising intercoat adhesion and protection.
Pot Life: 5-15 minutes (23°C)
Service Life: 4 hours (23°C)
Application Conditions:
- Surface Preparation: Steel surfaces should be sandblasted to Sa2.5 level or manually rust-removed to St3 level. Surface roughness should be 40-70μm.
- Temperature and Humidity: Substrate temperature should be between 0 to 50°C and at least 3°C above the dew point. Relative humidity should not exceed 85%.
Application Methods:
Airless Spraying:
-
- Thinner: Epoxy-specific thinner
- Nozzle Diameter: 0.4~0.5mm
- Spraying Pressure: 12~15Mpa (approximately 120~150kg/cm²)
-
Air Spraying:
-
- Thinner: Epoxy-specific thinner
- Nozzle Diameter: 2.0~3.0mm
- Air Pressure: 0.3~0.6Mpa (approximately 3~6kg/cm²)
-
Roller/Brush Application:
-
- Generally not suitable for large-scale application, limited to small-area touch-up painting.
Shelf Life: 1 year from the date of manufacture under normal storage and transport conditions.
Safety Precautions:
- Ensure proper ventilation in the work area.
- Strictly prohibit smoking and open flames in the work area and adjacent areas.
- Use explosion-proof electrical equipment.
- Metal impacts are strictly prohibited.
- Prevent the accumulation of static electricity.
- Wear necessary protective equipment.
- Avoid inhaling paint mist and avoid skin contact with paint and thinners.
- If paint accidentally splashes into the eyes, rinse immediately with plenty of water and seek medical attention.
- Properly dispose of empty paint cans and leftover paint to avoid environmental contamination.
- Take all other necessary safety and fire prevention measures based on the specific conditions of the site.
