  • Description

    Duranar ULTRA-Cool Fluoropolymer Coatings. This is a two coat infrared-reflective system for aluminum and steel substrates applied with a roll coating application. 

  • Chemistry

    Fluoropolymer (70% PVDF + 30% Acrylic)

  • Benefits

    • Premium, long-term infrared-reflective (IR) system
    • Available in a palette of light, medium and dark colors
    • Outstanding gloss and color retention versus polyester technology
    • Exceptional film integrity, color fade, chalk resistance
    • Strong corrosion resistance
  • Suggested End Uses

    • Building panels
    • High-end storefronts
    • Curtain walls
    • Roof panels
    • Aluminum composite and accent trim

Product Characteristics

Specification Test Standard Aluminum substrate Coated steel substrate

Technical Properties

1 Coated Steel includes the following types of steel: G90 hot dip galvanized, Galvalume®, and Zincalume®. 2 Fracturing or rupturing of substrate will rupture coatings. Heavy gauge and clad steel substrates impose limitations on formability. 3 Corrosion performance is dependent on properly cleaned and pretreated substrate. These test results are based on methods believed to be correct and were performed on laboratory prepared panels. This document is not a guarantee of future.
