TAZ0024 Metal Galv Zinc Diffusion Top Coat White Silver

SKU TAZ0024
Price

RM0.00

TCP0024 is a specialized topcoat designed for fasteners with inorganic zinc-aluminum primers, galvanized base coats, or Dacromet primers. This topcoat enhances the metal's bright silver aesthetic while delivering excellent anti-corrosion and oxidation resistance. The addition of advanced nano-materials boosts the wear resistance of the zinc-aluminum layer.

TECHNICAL DATA

Key Features:

  • Eco-Friendly:

    • Free from heavy metals, offering a green zinc-coating solution.

  • Durability:

    • Combines flexibility and hardness after curing.
    • Ensures no hydrogen embrittlement in the coating.

  • High Hardness:

    • Achieves a hardness level of 5H+ with exceptional wear resistance.

  • Superior Corrosion Protection:

    • When paired with inorganic zinc-aluminum primers, achieves over 800-1000 hours of neutral salt spray resistance 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

  • Ideal for anti-corrosion surface treatments of fasteners, such as:

  • Bolts
  • Screws
  • Nuts
  • Springs
  • Clamps
  • Stamped parts

INSTRUCTIONS OF USE

Instructions for Use and Precautions

Surface Preparation

  • Thoroughly clean the fasteners (galvanized screws) using solvents such as thinner to remove oil, dust, and other contaminants. Ensure the surface is oil-free, dust-free, and dry.

  • Open the TAZ0024 container and disperse the coating with an electric stirrer for 5-10 minutes.

Dip Coating Process

  • Immersion:

    • Place the galvanized screws in a 60-mesh filter and immerse them in the TAZ0024 for 10 seconds.
    • Remove and allow excess liquid to drip off. Transfer to a centrifuge.

  • Centrifuge Parameters:

    • Speed: 260-280 RPM
    • Time: 10-25 seconds, performed in two cycles:
      • Cycle 1: Rotate clockwise.
      • Cycle 2: Rotate counterclockwise.
    • After the first cycle, adjust the screw positions to ensure uniform coating coverage before proceeding with the second cycle.

  • Dilution:

    • If viscosity increases during use, dilute the coating with TAZ0024 special thinner to achieve a viscosity of 55±2S (measured at 25°C).
    • Add approximately 5-20% thinner by weight for adjustment.

Precautions

  • Ensure the workspace has forced ventilation during production.
  • The surface of the fasteners must be free from oil, dust, and dirt before coating.
  • Only use the TZA0024 specialized thinner for dilution.

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.
