CAZ0004 Ultra Clean Nano Coating for Multi Surface

Key Features:

• Self-Cleaning: Repels water-based pollutants, ensuring dry and sterile surfaces. Dust and dirt are easily removed with water or airflow.
• Anti-Pollution: Drastically reduces or eliminates contamination from dust, dirt, and liquids containing bacteria or radioactive substances.
• Anti-Corrosion: Prevents water and moisture in the air from contacting the surface, significantly reducing corrosion risks.
• Anti-Freeze: Keeps surfaces dry and moisture-free, preventing ice formation.
• Moisture Resistance: Maintains dryness and prevents liquid absorption.
• Outstanding Hydrophobic Properties: Water contact angle >150°, rolling angle <5°.
• Wide Temperature Range: Performs reliably from -40°C to 150°C.

Applicable Materials

• Compatible with all types of surface materials, including:
  • Metals: Steel, aluminum, and more.
  • Non-Metals: Plastics, textiles, leather, wood, footwear.

Curing Method

• Room Temperature Curing: Suitable for normal conditions.
• Heat Curing: Accelerates curing under controlled heat.

Application Scope

• Industrial and Structural Applications:
  • Communication tower antennas.
  • Military and civilian radars.
  • Anti-icing coatings for power lines and wind turbine blades.
• Automotive and Machinery:
  • Anti-contamination coatings for cars, concrete mixers, and construction vehicles.
• Surface Protection:
  • Concrete countertops, plastics, and textiles.

Surface Preparation

• Clean the Surface: Ensure the surface is free of old paint, rust, grease, oxidation, and debris. The substrate must be free of rust, oil stains, dust, and water marks.
• Immediate Application: Apply the coating promptly after cleaning to avoid recontamination by dust.
• Environmental Requirements:
  • Dust-free workspace.
  • Adequate ventilation or air suction systems to ensure coating quality.
• Spray Settings:
  • Spray pressure: 0.138–0.241 MPa.
  • Nozzle diameter: 0.5–1.27 mm.
  • Spray distance: 15–25 cm.
  • Recommended film thickness: 10–25 microns.
  • Application temperature: 10–30°C.
  • Relative humidity: 45–75%.

Coating Process

• Step 1: Base Coat Application

1. Mix Thoroughly: Stir the base coat well before use.
2. Spray Application: Use an HVLP spray gun for high-precision application.
3. Thin, Even Layers: Apply multiple thin and even coats to achieve a dried film thickness of 10–25 microns.
4. Drying Time: Allow the base coat to dry for 20–30 minutes. Use a heat gun or hairdryer to accelerate drying if needed.

Step 2: Surface Coat Application

1. Use a Separate Spray Gun: Do not use the same spray gun as the one for the base coat. Use a clean HVLP spray gun.
2. Thin, Even Layers: Apply multiple thin and even coats of the surface layer, ensuring the same coverage as the base coat.
3. Final Film Thickness: Achieve a dried film thickness of 10–25 microns.

Step 3: Drying and Curing

1. Hydrophobic Effect: The super-hydrophobic properties will appear 30 minutes after surface coat application, with optimal performance achieved after 2 hours.
2. Curing Options:
   • Air-dry at room temperature.
   • Heat curing to accelerate the process.

Maintenance and Care

• Dual-Coat System: Both base and top coats are required to achieve super-hydrophobic performance. Once fully cured, the coating effectively resists water intrusion.
• Cleaning: Use low-pressure water spray to clean the surface. Dust and dirt will easily wash away, leaving the surface dry and clean.
• Avoid Harsh Agents: Detergents, soaps, certain solvents (e.g., xylene, toluene, acetone), or high-pressure water streams may compromise the coating's performance.
• Reapplication: If the surface coat is damaged and loses its hydrophobic properties, reapply the surface coat to restore performance.

Storage

• Recommended Temperature: 18–32°C
• Shelf Life: 24 months.
