Fluorocarbon polymers, also known as fluoropolymers, are a class of organic polymers characterized by strong carbon-fluorine (C-F) bonds. These polymers feature carbon chains with fluorine atoms replacing hydrogen atoms, rendering them highly resistant to corrosion. They are widely used in architectural applications due to their durability and inert nature.
Different types of Fluorocarbon
-
PVDF (Polyvinylidene Fluoride)
-
FEVE (Fluorinated Ethylene Vinyl Ether)
-
PVF (Polyvinyl Fluoride)
PVDF
(Polyvinylidene Fluoride)
-
Application: Applied as high-performance coatings (e.g., Kynar® or Hylar®) on metal surfaces such as aluminum, steel, or galvanized steel for cladding, roofing, window frames, and curtain walls.
-
Benefits: Exceptional resistance to UV radiation, fading, chalking, corrosion, and chemical exposure (e.g., acid rain, pollutants). Retains color and gloss for 20–30 years, meeting standards like AAMA 2605.
-
Examples: PVDF-coated aluminum panels on skyscraper facades (e.g., Petronas Towers) or residential window frames for vibrant, durable finishes.
FEVE
(Fluorinated Ethylene Vinyl Ether)
-
Application: Used as coatings on metal, glass, or concrete surfaces for cladding, roofing, and exterior walls, often in high-gloss or custom finishes.
-
Benefits: Offers UV resistance and durability comparable to PVDF, with superior flexibility for complex substrates and excellent gloss retention. Allows for field-applied coatings, unlike PVDF, which is typically factory-applied.
-
Examples: FEVE-coated panels on commercial buildings or bridges, where high-gloss aesthetics and weather resistance are critical.
PVF
(Polyvinyl Fluoride)
-
Application: Applied as a thin-film coating or laminate on metal or plastic surfaces for exterior panels, roofing, or decorative elements.
-
Benefits: Excellent weatherability, UV resistance, and flexibility, though less chemically inert than PVDF. Often used as a film (e.g., Tedlar® by DuPont) for protective laminates.
-
Examples: PVF films laminated on aluminum siding for residential buildings to protect against weathering and maintain color.
