TAZ0028 Metal Galv Zinc Diffusion Top Coat Bright Silver

SKU TZT0028
Price

RM0.00

TAZ0028 is a specialized topcoat designed for fasteners with inorganic zinc-aluminum base layers, galvanized primers, or Dacromet coatings. This high-performance coating enhances the metallic brilliance of fasteners, while significantly improving rust resistance and oxidation resistance. The addition of nano materials further boosts the wear resistance of zinc-aluminum layers, ensuring durability even under demanding conditions.

TECHNICAL DATA

Key Features:

  • Eco-Friendly Galvanization: Free of heavy metals, ensuring environmentally safe applications.
  • Balanced Flexibility and Hardness: Cured coatings exhibit excellent flexibility without hydrogen embrittlement, combined with high durability.
  • High Hardness: Achieves a hardness level exceeding 5H, with exceptional abrasion resistance.
  • Superior Corrosion Resistance: When paired with an inorganic zinc-aluminum primer, withstands 800-1000 hours of neutral salt spray without substrate corrosion.

Applicable Materials

  • Inorganic zinc-aluminum base layers.
  • Galvanized primers.
  • Dacromet coatings on fasteners.

Curing Method

  • Coating Temperature: 15–35°C.
  • Environmental Temperature: 10–45°C.
  • Baking Temperature: 200°C for 30 minutes (using a conveyor belt furnace or box furnace).

Application Scope

  • Anti-corrosion surface treatment for fasteners such as bolts, screws, nuts, springs, clamps, and stamped parts.

INSTRUCTIONS OF USE

Instructions for Use and Precautions

 

Preparation Steps

  • Surface Cleaning:

    • Remove oil and dust from the workpieces, ensuring the surface is clean and free of contaminants.

  • Stirring the Coating:

    • Open the TZT0028 and use an electric mixer to disperse the contents for 5-10 minutes thoroughly.

Instructions for Use

Preparation Steps

Surface Cleaning:

  • Remove oil and dust from the workpieces, ensuring the surface is clean and free of contaminants.

Stirring the Coating:

  • Open the TZT0028 and use an electric mixer to disperse the contents for 5-10 minutes thoroughly.

Application Guidelines

Dip-Centrifugal Process:

  • Step 1: Dipping:

    • Place galvanized screws, Dacromet-coated parts, or inorganic zinc-aluminum primer-coated components in a 60-mesh filter net.
    • Immerse the components in the TZT0028 for 10 seconds.
    • Remove the parts and let the excess coating drain off.

  • Step 2: Centrifuging:

    • Transfer the parts to a centrifuge.
    • Set the speed to 220-230 RPM for 10-13 seconds per cycle. Perform two cycles (one clockwise, one counterclockwise per cycle).
    • After the first cycle, adjust the screws' positions to ensure complete coating coverage before starting the second cycle.

  • Viscosity Adjustment:

    • If the viscosity becomes too high during use, add deionized water and adjust to 55±5 seconds (measured at 25°C, dispersed at 600 RPM for 10 minutes).

  • Curing Parameters:

    • Pre-baking: 70°C for 5-8 minutes.
    • Final Curing: 160°C for 25-30 minutes.

Precautions

  • Ensure adequate ventilation in the production area when using TZT0028.
  • The surface of the workpieces must be free from dirt or oil before application.
  • Always use deionized water for thinning the water-based topcoat.

Usage Cycle

  • Shelf Life: 2-3 months from opening. Use as soon as possible to avoid material degradation. Use the product promptly to ensure performance.

Storage

  • Recommended Storage Temperature: 18–25°C.
  • Usage Period: 3 months.

Environmental

  • For safety recommendations and transportation rules, please refer to the SDS.
