Most formulators recognize the LUMIFLON resin family as a family of fluoropolymers. However, that description is only part of the complete story. A better definition for LUMIFLON resins is that they are “hybrid” fluoropolymers. In order to build in the properties necessary for the creation of resins that are user-friendly, AGC selected vinyl ethers as comonomers for the chlorotrifluoroethylene monomers, which pass on the ability to solvate these resins in a wide variety of commercial solvents. In addition, these vinyl ether comonomers contain hydroxyl groups, which add functionality to these resins. The final product is a fluoropolymer resin that functions the same as a polyol and can be used in 2 component ambient-cure coatings that utilize isocyanates as the crosslinking resin component.
Now, because of the vinyl ether presence, typical properties connected to the standard fluoropolymers like polytetrafluoroethylene (PTFE) or ethylenetetrafluoroethylene (ETFE) are somewhat diminished with the LUMIFLON resins. However, they do exhibit strong weatherability characteristics and above average chemical resistance properties. And, because this marriage of fluorinated monomers and vinyl ether monomers is successful, high gloss properties can be realized. Lastly, the LUMIFLON resins also show a wide range of compatibility with both acrylic and polyester polyols. This will allow for the engineering of paint formulations to specific physical properties like increased flexibility and abrasion resistance.
