Which coil coating system fits your application?
Primealux Alloys supplies prepainted coil in PVDF, PUPA, HDPE, PE, and epoxy coating systems. Each trades off UV resistance, formability, and cost differently. Pick your environment or your coating below to see the match.

What's actually in a coating system?
A coated coil is several layers, not one. Switch systems below to see how the stack changes.
PVDF (fluoropolymer)
Facades, cladding, architectural roofing, coastal and high-UV exposure
View coatingPUPA (polyurethane-polyamide)
High-wear, high-cycle uses: the standard choice for rolling shutters
View coatingHDPE (high-durable polyester)
General exterior construction (roofing, gutters) where PVDF-grade longevity isn't required
View coatingPE (polyester)
Interior use and light exterior service with limited UV exposure
View coatingEpoxy / Epoxy-PE / Acrylic
Primers, interior or back-coat applications; acrylic for cost-sensitive interior use

| System | Best for | Notes |
|---|---|---|
| PVDF | Facades, cladding, architectural roofing, coastal and high-UV exposure | Exceptional color and gloss retention, minimal chalking over decades. Industry-typical exterior life: 20 to 30 years. |
| PUPA | High-wear, high-cycle uses: the standard choice for rolling shutters | Abrasion- and mar-resistant film. Also the coating used in the highest-recycled-content coil option. See the sustainability note on the coil hub. |
| HDPE | General exterior construction (roofing, gutters) where PVDF-grade longevity isn't required | Strong weathering at moderate cost. Industry-typical exterior life: 10 to 15 years. |
| PE | Interior use and light exterior service with limited UV exposure | Will chalk and fade faster outdoors than fluoropolymer systems. Industry-typical exterior life: 5 to 10 years. |
| Epoxy | Primers, interior or back-coat applications; acrylic for cost-sensitive interior use | Not recommended as an exposed exterior finish on its own. |
| PU (polyurethane) | Where mechanical toughness and moderate exterior performance are both needed | Good flexibility and abrasion resistance. |
Coating warranties run 5 to 20 years depending on application and installation environment (coastal vs. inland). Confirmed per specification, not a flat number we advertise site-wide.
