ES100 Solvent-Free Moisture-Resistant Epoxy Coating

ES100 is a high-performance solvent-free modified epoxy coating designed for heavy-duty anti-corrosion applications on steel surfaces. This environmentally friendly formulation can be directly applied to dry or wet surfaces, compatible with both new and old steel substrates. It adheres firmly to rust spots and sound existing coatings, serving as a primer, intermediate coat, or topcoat. With zero harmful solvent emissions, excellent impact resistance, non-flammability, superior chemical resistance, and no dew point or relative humidity restrictions, ES100 offers exceptional corrosion protection and strong substrate adhesion while reducing surface preparation costs.

Application Guidelines

Surface Preparation:
- High-pressure water jetting, dry/wet blasting, or mechanical treatment.
- Blast cleaning: Sa2 (ISO 8501-1:2007); Ultra-high-pressure water: Wj2-M (SSPC SP12-VIS4(I)/NACE No.7); Mechanical: St3 (ISO 8501-1:1988).
Mixing Procedure:
- Stir base material until smooth (<2 minutes).
- Gradually add curing agent and mix continuously for 3 minutes using a variable-speed electric mixer. Avoid overmixing to prevent accelerated curing.
Application:
- Airless spraying recommended (use 60:1 or higher pump ratio, 0.48–0.79 mm nozzle).
- Ensure equipment and fluid pathways are clean and free of water/solvents. Adjust pump ratio for long pipelines or low temperatures.
- Maintain proper ventilation for worker safety and coating performance.

Safety Precautions

Hazards: May cause eye/skin irritation and respiratory irritation (vapors). Risk of skin allergy.
Protective Equipment: Use eye/face protection, gloves, and respiratory masks.
First Aid: Flush eyes with water for 15+ minutes if exposed. Wash skin with soap. Seek medical advice for persistent irritation.
Handling: Avoid prolonged contact. Dispose of mixed material carefully due to exothermic reaction.
