Drying Time & Overcoating Interval
| Substrate Temp. (∘C) | Surface Dry (min) | Hard Dry (h) | Min. Overcoating (h) | Max. Overcoating Interval |
| 5 | 160 | 32 | 20 | 72 h |
| 10 | 90 | 20 | 10 | 72 h |
| 20 | 50 | 12 | 6 | 72 h |
| 30 | 30 | 8 | 4 | 72 h |
Surface Preparation
For steel plates, the substrate surface must be blast-cleaned to Sa2.5 standard to remove mill scale, grease, salt, and rust, with the surface roughness controlled between 40–$75\,\mu\text{m}$. For concrete storage tank walls, the surface must be sound, dry, free of hollows/voids or cracks, with a moisture content of $\le 8\%$. Thorough degreasing and dust removal must be performed prior to application. Keep the interior of the tank clean and dry. Any old coatings must be completely abraded or scraped off.
Application Conditions
The application temperature range is 5–$35^\circ\text{C}$, with relative humidity (RH) below 80%. The substrate temperature must be at least $3^\circ\text{C}$ above the dew point. As this product is solvent-free and features low volatility, maintaining normal ventilation inside the storage tank is sufficient. Application is strictly prohibited during condensation, rain, snow, or heavy fog. Anti-static measures must be implemented during application inside tanks.
Coating System
-
Preceding Coat: Epoxy zinc-rich primer, or epoxy anti-corrosive primer.
-
Subsequent Coat: Epoxy topcoat, or anti-static epoxy coating.
-
Note: Blending or compatibility with alkyd-based or oleoresinous bituminous paints is strictly prohibited.
Packaging Specifications
-
Base (Part A): 24 kg
-
Curing Agent (Part B): 3 kg
Storage
This product must be stored in a cool, dry, and well-ventilated explosion-proof indoor warehouse, away from open flames 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 is a solvent-free coating with no organic solvent evaporation and is classified as non-flammable. Maintain good ventilation at the application site. Application personnel must wear respirator masks, safety glasses, anti-static work clothing, and solvent-resistant gloves. Avoid prolonged contact with the paint film. In case of skin contamination, wipe with a suitable cleaning oil 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.
