Surface Preparation
New Steel: Abrasive blast-cleaning to Sa2.5 grade or power-tool cleaning to St3 grade.
Shop-Primed Steel: Damaged areas and rusted parts must undergo secondary rust removal to reach Sa2.5 or St3 grade.
Zinc-Salt/White Rust Removal: For shop primers that have generated zinc salts, sweep-blasting or high-pressure fresh water cleaning must be used to thoroughly remove the salts.
Welds & Burned Areas: Weld seams and thermally damaged areas must be treated and cleaned to Sa2.5 or St3 grade.
Application Conditions
Temperature & Humidity: The application temperature range is 5 ~ 30°C with a relative humidity (RH) below 85%. The substrate surface temperature must be at least 3°C above the dew point.
Measurement: Temperature and humidity should be measured in the immediate vicinity of the substrate.
Constraints: Coating operations are not recommended if the substrate surface temperature exceeds 40°C. Do not apply during adverse weather conditions such as rain, snow, or heavy wind/sandstorms.
Coating System Compatibility
Subsequent Coats (Intermediate/Topcoats): Waterborne Epoxy Intermediate Paint, Waterborne Polyurethane Topcoat, Waterborne Acrylic Topcoat, or solvent-borne Epoxy 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 plenty of water and seek medical attention promptly.
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.
