Flurothane® II

Recognized as an most outstanding technical achievement with the prestigious R&D 100 Award, Flurothane®II coatings are formulated to protect and enhance building projects in tough environments. The Flurothane II formulation combines two of the most effective coating technologies known to the coil coating industry: Urethane and the fluoropolymer chemistry of Kynar 500® or Hylar 5000® resin. They have proven effective against ultraviolet rays, corrosion, humidity, acid rain, and a wide range of chemicals and other pollutants. Flurothane II resists chalking, fading, chipping, cracking and dirt.


Flurothane II coatings provide a number of unique benefits including:

  • Exceptional resistance to sun, rain and other natural elements
  • Superior scratch resistance
  • Exceptional dirt and stain resistance
  • Excellent overall adhesion
