Fluorocarbon-Coated Coils vs. Standard Polyester-Coated Coils: A Technical Breakdown
Today, we analyze five core differences between these two coating technologies from a technical perspective:
I. Coating Composition & Process
Fluorocarbon Coating: Composed of PVDF resin (≥70% polyvinylidene fluoride) and ceramic pigments, forming a dense cross-linked structure through high-temperature baking.
Polyester Coating: Uses polyester resin with conventional pigments, creating a basic protective layer after curing.
Though both employ roll-coating, fluorocarbon’s molecular structure is far more stable.
II. Weather Resistance (Test Data)
Salt Spray Test (3,000 hours):
Fluorocarbon: No rust, gloss retention >95%.
Polyester: Gloss retention 65%-75%.
UV Accelerated Aging:
Fluorocarbon lifespan: 20-25 years vs. polyester’s 5-10 years.
Thermal Cycling (-50°C~120°C):
Fluorocarbon: No cracking/delamination; polyester develops micro-cracks.
III. Recommended Applications
Fluorocarbon is ideal for:
Coastal areas (ports/shipyards) with high salt exposure.
Industrial zones with severe pollution.
Architectural facades of landmark buildings.
Extreme climates (plateaus/cold regions).
Polyester suits:
Inland industrial plants.
Warehousing/logistics buildings.
Temporary structures.
Non-exposed interior layers.
IV. Lifecycle Cost Analysis (20-Year Horizon)
Fluorocarbon reduces maintenance costs by ~40%.
Adds 25%-30% long-term value.
Extends renovation cycles by 2-3x.
Recommendation:
Choose fluorocarbon for critical projects/harsh environments; polyester for budget-conscious conventional builds.
