What is the standard type of painted finish for interior and exterior architectural applications?
The industry standard for high-performance painted finishes is a 70% fluoropolymer, also known as Kynar 500® or Hylar 5000®. This class of finish is easy to maintain and is extremely resistant to wear and fading. All Kynar 500® and Hylar 5000® finishes meet or exceed the standards outlined in the AAMA 2605 specification. This type of finish is acceptable in both interior and exterior applications. For interior applications, a more economical 50% fluoropolymer or baked enamel is available. These finishes do not perform to the level of the 70% fluoropolymer and are not recommended for exterior architectural applications. All pre-finished PAC-CLAD® painted sheet stocked at ASCO utilizes the 70% Kynar 500® and Hylar 5000® finishes. Typically, all post-coated painted material is finished with a 70% fluoropolymer unless otherwise specified.
