Key Differences for PVDF & PE Coated Aluminum Coils & Sheets

What Are PVDF & PE Coated Aluminum?

PVDF Coated Aluminum

PVDF (fluorocarbon) coated aluminum uses a high-performance topcoat with 70% or more PVDF resin.
For example, it may use Kynar 500.
It is applied using a 2-coat, 2-bake process or a 3-coat, 3-bake process.
It is cured at 230–260°C. The ultra-stable C-F chemical bond delivers unmatched long-term weather, UV, and corrosion resistance.

PE Coated Aluminum

PE (polyester) coated aluminum uses a polyester resin topcoat, applied via 1-coat/1-bake or 2-coat/2-bake, cured at 180–220°C. It offers good formability, vibrant color options, and cost efficiency for moderate environments.

PVDF coated aluminum for long-term, high-exposure outdoor projects requiring maximum durability and low maintenance in harsh climates.

PE coated aluminum for cost-sensitive applications, interior use, or parts requiring extensive forming where flexibility and color variety matter most.
