Colorite FluoroCarbon

ColoRite FluoroCarbon is a Paint system comprising hot-dip galvanized steel sheet with a minimum Zinc coating mass of 275 gsm (G90) that is painted on and oven cured with FluoroCarbon paint manufactured from Kynar 500 or Hylar 5000 resin, along with a custom-formulated high-performance primer. This produces a nominal paint dry film thickness of 25 microns on the top surface (inclusive of primer) and 10 microns on the bottom (inclusive of primer). ColoRite FluoroCarbon was developed to provide extra durability, excellent weatherability, and high formability for exterior applications.
