Drying Time & Overcoating Interval
| Substrate Temp. (°C) | Surface Dry (min) | Hard Dry (h) | Min. Overcoating Interval (h) | Max. Overcoating Interval |
| 5 | 180 | 32 | 20 | No limitation |

Surface Preparation
The steel structure surface must be clean, dry, and completely free of oil stains, salts, and mill scale.
Cleanliness must reach Sa2.5 grade via abrasive blasting, or no less than St3 grade using power-tool cleaning.
Control the surface profile (roughness) within 40 to 75 μm. Apply the primer promptly after rust removal to prevent secondary flash rusting.
When overcoating, existing old paint films must be abraded and roughened, and all loose or peeling areas must be thoroughly removed.
Application Conditions
Temperature & Humidity: The application temperature range is 5 ~ 35°C with a relative humidity (RH) below 80%. The substrate surface temperature must be at least 3°C above the dew point.
Constraints: Application is strictly prohibited during high humidity, condensing conditions, or heavy fog to prevent the zinc powder from experiencing flash rust. Do not apply outdoors during rain, snow, or severe wind and sandstorms.
Sub-Zero Warning: Construction and storage ambient temperatures must never fall below 0°C. Freezing temperatures will break the emulsion phase and ruin the coating.
Coating System Compatibility
Subsequent Coats (Intermediate/Topcoats): Epoxy MIO (Micaceous Iron Oxide) Intermediate Paint, Waterborne Epoxy Topcoat, Waterborne Polyurethane Topcoat, or Acrylic Topcoat.
Packaging Specifications
Base (Part A): 20 kg
Curing Agent (Part B): 2 kg
Storage
Store this product in a cool, dry, and well-ventilated indoor warehouse. Ensure protection against freezing.
The storage temperature range must be maintained between 5°C and 30°C. The shelf life is one year under standard temperature conditions.
The base and curing agent must be stored separately.
Safety Precautions
Maintain excellent ventilation throughout the mixing and application sites.
Applicators must wear appropriate personal protective equipment (PPE) to prevent inhalation of paint mist and avoid contact with eyes or skin.
If paint contacts the skin, wash immediately with soap and water. If it splashes into the eyes, rinse immediately with a large volume of water and seek immediate medical attention.
Disclaimer
The protective performance of any coating largely depends on application factors. Surface preparation and film thickness will directly affect the service life of the coating. Users must ensure compliance with the specified application conditions.
The data provided in this manual are theoretical values or derived from experimental accumulation. Some data may change due to continuous product improvements without prior notice.
