Carbon emission reduction ZFC

What is Zinc Flake Coating (ZFC)?

As a high corrosion-resisting zinc coating technology that forms thin and solid ceramic zinc sheet on the surface of material at room temperature through mutual coupling of zinc flake and ceramic inorganic binder of the sheet on metal surface, it is anticorrosive technology with KS standard (molten zinc plating) or higher effect.

Characteristic

  • Blocks corrosion factors by forming a laminated structure using plate-shaped zinc powder to increase coating film density
  • The coating film has a ceramic inorganic binder to inhibit zinc oxidation and elution, and additionally blocks corrosion factors through network structure.
  • Even if corrosion factors reach the base material, rust occurrence is prevented through the zinc sacrificial anode structure.
  • Blocks corrosion factors, inhibits zinc oxidation, and ensures excellent corrosion resistance with triple sacrificial anode structure

After 40 cycles of composite corrosion testing

<Hot-dip galvanized 80㎛> <ZFC plating (silver)20㎛>

  • In the composite corrosion test (“Salt water spray -> high-temperature drying -> high temperature humidity -> high-temperature drying” 12 hours experiment with 1 cycle), the hot-dip galvanized guardrail was rusted. However, the carbon emission reduction ZFC guardrail demonstrated excellent corrosion resistance without rust occurrence.

Features of carbon discharge reduction ZFC guardrail

1. Eco-friendly

  • The process of ZFC production ensures excellent carbon emissions as it does not use fossil fuel energy
  • ZFC products feature eco-friendly performance that does not emit the 6 heavy metals and harmful VOCs that are harmful to the human body.

2. Reduces carbon dioxide emission through a room temperature drying method

  • The method reduces carbon dioxide emissions as it does not use energy for drying

3. Zinc metal coating

  • Zinc metal coating protects materials through the zinc sacrificial anode method

4. Excellent corrosion resistance even for thin coating

  • Zinc stabilization and suppression of zinc activity, excellent durability of zinc layer with the effect of an inorganic binder
  • Excellent material protection ability with double-corrosion effect of blocking corrosion factors and sacrificial anode method

5. Rapid drying ensures excellent workability

  • Excellent workability with short stand-by time when coating a large amount of products with the ability to set-to-touch within 10 minutes after coating

6. Localization

  • Securing national competitiveness through localization
