ReHarmony Adamas Ultra Clear Coat

ReHarmony Adamas Ultra Clear Coat is a high-performance coating system composed of a hydroxyl-containing resin component and an isocyanate-based curing agent. When mixed in a specific ratio, the two components undergo a cross-linking reaction to form a durable and protective film.

This topcoat offers excellent weather resistance, outstanding physical and chemical stability, high gloss, and strong decorative appeal. With superior application performance and eco-friendly properties, it is widely used in automotive coatings, shipbuilding, machinery manufacturing, furniture, architectural decoration, and electronics industries.

Surface Preparation Technical Requirements

1. Surface Cleaning

• Degreasing: Remove oil/grease using organic solvents (acetone, mineral spirits) or specialized degreasers to ensure oil-free surfaces for optimal coating adhesion.

• Dust removal: Eliminate dust/particles with compressed air, vacuum or clean cloth to prevent contamination.

2. Surface Abrasion

• Metal surfaces:

  • Sand with 180-240 grit for smooth metals

  • Use 240-320 grit after rust/old coating removal

• Plastic surfaces:

  • Lightly abrade with 1000-1500 grit

  • Avoid excessive sanding to prevent deformation

• Wood surfaces:

  • Sand along grain direction

  • Progress from 120 to 240-320 grit

3. Moisture Elimination

• Thoroughly dry surfaces using cloth, heat guns or air blowers

• Prevent coating blisters/adhesion failure by ensuring complete dryness

4. Special Treatments

• Metals: Apply phosphating/passivation after preparation to enhance corrosion resistance

• Plastics: Use flame/plasma treatment or specialty primers for improved adhesion

• Wood:

  • Maintain 8-12% moisture content

  • Apply sealer on knotty areas to prevent resin bleeding

Key Considerations

1. Environmental Conditions

• Maintain 5-35°C temperature

• Keep relative humidity ≤85%

• Implement dust control measures in windy conditions

2. Tool Requirements

• Use clean, dry abrasives (silica sand/steel grit) for blasting

• Follow "coarse-to-fine" sanding sequence

3. Quality Standards

• Visual inspection:

  • No oil, rust or dust

  • Absence of pits/particles

  • Rounded edges

• Adhesion test: Cross-cut method per ISO 2409

Note: All preparation steps must be completed before coating application to ensure optimal performance.
