TAZ0025 Metal Galv Zinc Diffusion Coating High Viscocity

Key Features:

• Eco-Friendly Zinc Coating: Free of heavy metals, ensuring a sustainable solution for galvanization.
• Balanced Durability: Cured coating offers high hardness paired with a degree of flexibility.
• High Hardness: Achieves a hardness rating of 4H+, with excellent wear resistance.
• Exceptional Corrosion Protection: Withstands over 300 hours of neutral salt spray testing.
• Superior Corrosion Resistance: Provides exceptional protection against environmental and chemical corrosion.
• No Hydrogen Embrittlement: Unlike traditional galvanization, this process eliminates the risk of hydrogen embrittlement, making it ideal for high-stress components.
• High Heat Resistance: Capable of withstanding temperatures up to 300°C, compared to traditional zinc coatings which fail at 100°C.
• Excellent Adhesion and Recoatability: Strong bonding with the metal substrate and compatibility with additional coatings, ensuring easy painting or organic coating application.
• Exceptional Penetration: Effectively coats hard-to-reach areas, such as deep holes, narrow gaps, and internal pipe walls, which are challenging for electroplating.
• Eco-Friendly Process: Zero pollution or hazardous waste, significantly reducing environmental impact and treatment costs.
• Minimal Pre-Treatment: Requires no surface preparation for oil or rust removal, enabling direct application on clean steel surfaces.

Applicable Materials

• Metal workpieces requiring corrosion-resistant surface treatment.

• Curing Method

• Baking Temperature: 230°C for 30 minutes (workpiece surface temperature).

Main Components

• Metallic Elements: Ultra-fine zinc and aluminum flakes.
• Solvents: Inert organic solvents such as S100.
• Wear-Resistant Additives: Components like PTFE to enhance durability.
• Special Organic Compounds: Bind the coating material for effective adhesion.

Mechanism of Corrosion Protection

• Barrier Effect: Overlapping zinc and aluminum flakes form a layered shield, impeding water, oxygen, and corrosive agents from reaching the substrate.
• Passivation: During the coating process, a dense passivation layer forms through chemical reactions, enhancing corrosion resistance.
• Cathodic Protection: Functions similarly to traditional galvanization, offering sacrificial protection to the substrate.

Application Scope

• Ideal for corrosion protection on:
  • Embedded components.
  • Angle irons.
  • Lamp posts.
  • Railings and fences.

Instructions for Use and Precautions

Preparation

• Mixing: Open the TAZ0025 container and use an electric mixer to disperse for 2 minutes.
• Dilution: Add 10-30% of the specialized thinner to TAZ0025, ensuring viscosity is adjusted to 15-18 seconds using a Ford Cup No. 4 (25°C). Stir thoroughly and transfer the mixture to the coating tank.
• Viscosity Maintenance: If the viscosity increases during use, add the specialized thinner to readjust to 15-18 seconds (25°C).

Application Environment

• Ensure the production area is well-ventilated.
• The surface of the workpiece must be free of dirt and grease.

Curing Guidelines

• Optimal Baking Temperature: Follow the recommended curing temperature (230°C for 30 minutes) precisely.
• Temperature Control:
  • Baking at too low a temperature results in incomplete crosslinking.
  • Baking at excessively high temperatures may cause coating chalking, leading to a loss of corrosion resistance.

Usage Cycle

• Shelf Life: 2-3 months from opening. Use as soon as possible to avoid material degradation.

Storage

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