Sherwin-Williams® is chosen more often than any other brands of PVDF-based coatings. For PVDF exterior metal coatings systems, none is more trusted than our premium Fluropon coatings, which are fluoropolymer, containing 70% polyvinylidene difluoride (PVDF) resins. Field- and time- proven, they meet or exceed the most rigorous ASTM performance standards.
