In the window, door and façade industry, PFAS are mainly used in fluoropolymer-based surface coatings and certain low-friction or high-performance components.
The most relevant application is PVDF (polyvinylidene fluoride) coating systems for aluminum profiles, façade panels, curtain walls and architectural doors. PVDF belongs to the fluoropolymer group and is therefore considered part of the broader PFAS family. These coatings are typically applied as liquid or coil coatings for high-performance architectural applications.
PVDF is used because it provides:
– excellent UV and weather resistance,
– outstanding color retention and gloss stability,
– high chemical and corrosion resistance,
– low chalking and dirt pickup,
– long service life, especially in harsh climates and highly exposed façades.
PFAS-related materials may also be present in:
– PTFE-based sliding or friction-reducing elements in hardware systems, specialty gaskets using fluorinated elastomers,
– ETFE films used in selected façade applications.
– Fire resistant coatings
The main alternatives to fluoropolymer-based coatings are:
– super durable polyester (SDP) powder coatings,
– hyper-durable polyester systems,
– fluorine-free architectural coating technologies,
– anodizing in selected applications.
These alternatives are used to reduce or eliminate PFAS content while still providing high durability and weather resistance. Polyester-based systems are currently the most common alternative for architectural aluminum because they offer good outdoor performance, are widely available and support easier recycling and regulatory compliance
