EP002 Epoxy Sealing Paint

General Description and Product Characteristics

• Superior Permeability: Ensures deep penetration into concrete substrates.
• Easy Application: Suitable for pre-coating preparation on clean concrete surfaces.
• High Compatibility: Ideal for high-performance paint systems and chemical-resistant coating configurations.

Technical Specifications

Packaging, Storage, and Shelf Life

• Packaging: Two-component system, available in 20L containers.
• Storage: Store in a cool, well-ventilated area, avoiding excessive heat. Ensure containers are tightly sealed and comply with local regulations.
• Shelf Life: 1 year under recommended storage conditions.

Application Guidelines

Surface Preparation

1. Contaminant Removal: All release agents, oils, and other contaminants must be eliminated via sandblasting, thermal cleaning, or appropriate cleaning agents.
2. Concrete Treatment:
   • For mechanical methods: Use sandblasting, high-pressure freshwater jetting, or power tools to remove debris and create a rough, sound surface.
   • For chemical methods (if mechanical treatment is unavailable):
     • Pre-soak concrete with freshwater to protect steel reinforcement.
     • Apply a 5% (by weight) nitric or phosphoric acid solution, let sit for 3–4 minutes, then rinse thoroughly with freshwater.
     • Neutralize with a 5% (by weight) NaOH solution followed by freshwater rinsing.
3. Post-Treatment Requirements:
   • Surface must be smooth, rough, and free of loose materials, with a pH range of 6.5–8.0.
   • Allow at least 2 days of ventilation drying (65% relative humidity, 20°C).
   • Concrete must be fully cured (approximately 28 days for ordinary Portland cement) with surface moisture ≤4%.
   • Ensure substrate temperature is above 10°C during application and curing.
   • Quality control: Scratch the surface with a hard blade—only a clear, shallow mark should be visible, indicating a sound substrate.

Mixing and Dilution

• Mixing: Thoroughly blend the entire contents of each base material container. Add the curing agent and stir for 3 minutes using a variable-speed power mixer. Avoid overmixing to prevent accelerated curing.
• Dilution: Dilution is generally unnecessary. If required, use a maximum of 5% diluent, subject to local VOC and air quality regulations.

Safety Precautions

• Hazards: May irritate eyes and skin; vapors may cause respiratory allergies in sensitive individuals. Risk of skin allergic reaction.
• Protective Measures: Wear eye, skin, and respiratory protection (e.g., suitable respirator). Avoid inhalation of vapors and contact with eyes/skin.
• First Aid:
  • In case of eye contact: Flush with 清水 (clean water) for at least 15 minutes and seek medical attention.
  • In case of skin contact: Remove contaminated clothing, wash skin with soap and water.
  • If breathing stops: Provide artificial respiration and immediately consult a physician.
