Flurothane® IV

Building projects located in extremely harsh and hostile environments such as those found in coastal and industrial locales need the added protection against salt spray and chemical corrosion that Flurothane® IV delivers. Recognized with the prestigious R&D Award for outstanding technical achievement, Flurothane IV combines two of the most effective coating technologies known to the coil coatings industry: Urethane and the fluoropolymer chemistry of Kynar 500® or Hylar 5000® resin. Flurothane IV Coating


Flurothane IV coatings provide a number of unique benefits including:

  • Exceptional resistance to ultraviolet rays, corrosion, humidity, acid rain and a wide range of chemicals and other pollutants
  • Superior resists chalking, fading, chipping, cracking, and dirt
  • Exceptional dirt and stain resistance
  • Excellent overall adhesion
