Prepainted Galvanized Steel Coil Coatings
The multi-layer coating structure enhances the durability and color retention of the steel coil.
- Primer: Provides adhesion and a foundation for corrosion protection.
- Topcoat: We utilize materials such as polyester (PE), silicone-modified polyester (SMP), high-durability polyester (HDP), and polyvinylidene fluoride (PVDF). This ensures long-lasting weather resistance.
- Backcoat: Enhances corrosion resistance and bond strength.
This layered protection helps the PPGI coil resist tough weather, UV light, and wear from use.
PPGI Production Process
- Uncoiling and Cleaning: First, we perform preliminary treatment on the galvanized steel sheets. Our workers remove dirt, oil, and oxides from the surface.
- Chemical Pretreatment: A conversion coating is applied to enhance paint adhesion.
- Primer Application: This step ensures strong adhesion and rust protection.
- Topcoat/Backcoat: We apply the selected color and surface treatment based on customer specifications.
- Curing and Cooling: We harden the paint film through high-temperature curing, followed by cooling. This step enhances the durability of the PPGI.
- Recoiling and Packaging: The coils are delivered for export and industrial use.
