Drying Time & Overcoating Interval
| Substrate Temp. (∘C) | Surface Dry (min) | Hard Dry (h) | Min. Overcoating (h) | Max. Overcoating Interval |
| 5 | 180 | 36 | 24 | Extended / No maximum limit |
| 15 | 100 | 24 | 12 | Extended / No maximum limit |
| 20 | 60 | 16 | 8 | Extended / No maximum limit |
| 30 | 35 | 10 | 6 | Extended / No maximum limit |
Surface Preparation
For steel structures, the substrate must be blast-cleaned to Sa2.5 standard to remove mill scale, grease, salt, and rust. For concrete substrates, the surface must be sound, dry, free of hollows/voids, and free of loose dust, with a moisture content of $\le 8\%$, and ground smooth. Loose or weak substrates require consolidation treatment. Existing/old paint films must be thoroughly abraded/roughened and cleaned prior to application.
Application Conditions
The application temperature range is 5–$35^\circ\text{C}$, with relative humidity (RH) below 80%. The substrate surface temperature must be at least $3^\circ\text{C}$ above the dew point. Application under damp, condensing, or rainy conditions is strictly prohibited to prevent the paint film from blistering or whitening. Do not perform outdoor application during high winds, sandstorms, or heavy fog. Maintain good ventilation during application to prevent dust from settling on the uncured film surface.
Coating System
-
Preceding Coat: Epoxy zinc-rich primer, or epoxy anti-corrosive primer.
-
Subsequent Coat: Epoxy topcoat, or polyurethane topcoat.
-
Note: Avoid compatibility with alkyd-based coatings to prevent adverse chemical reactions.
Packaging Specifications
-
Base (Part A): 21 kg / 28 kg
-
Curing Agent (Part B): 3 kg / 4 kg
Storage
This product must be stored in a cool, dry, and well-ventilated indoor warehouse, away from fire and heat sources, and protected from direct sunlight and rain. The storage temperature should be between 5–$30^\circ\text{C}$. Base and curing agent must be stored separately. The shelf life is 12 months under normal room temperature conditions.
Safety
This product contains organic solvents and is a flammable anti-corrosive coating. All sources of ignition are strictly prohibited at the application site, and good ventilation must be maintained. Application personnel must wear respirator masks, safety glasses, and solvent-resistant gloves. Avoid inhalation of paint mist. In case of skin contact, wipe with a dedicated thinner first, then wash thoroughly with soap and water. In case of eye contact, rinse immediately with plenty of fresh water and seek medical attention.
Disclaimer
-
The protective performance of any coating depends largely on the application process. Application factors such as surface preparation and dry film thickness will directly impact the service life of the coating system. Users must ensure compliance with the specified application conditions when using this product.
