The Ultimate in Coating Performance and Durability
The combination of carbon-fluorine bonds with carbon-hydrogen atoms gives PVDF an extremely stable structure. Hylar® 5000S PVDF is inherently inert and withstands long-term UV and gamma radiation resulting in excellent color and gloss retention without chalking.
PVDF also resists acids, alkalis, and oils. These coatings ensure a long-lasting, rich, colorful, durable finish and gloss with relatively no visible signs of ageing despite years of relentless sun, temperature extremes, and harsh environmental conditions. Hylar® PVDF is transparent to UV light, making it completely resistant to degradation by UV light.
Coil or Spray Application
It is possible to prepare premium architectural coatings using Hylar® 5000S PVDF powder as a base and adding an acrylic resin plus appropriate inorganic pigments,.
A liquid coating is formed by dispersing Hylar® 5000S PVDF powder under very high shear into a blend of acrylic and latent solvents. This dispersion is unaffected by ambient temperatures, but when heated the powder particles dissolve and coalesce. By manipulating the solvent balance, a stable dispersion is produced that can be handled and applied much like standard liquid coatings, and then heat-cured into adherent integral films.
Hylar® 5000S PVDF-based coatings may be either coil or spray applied.
Top-tier Performance over the Competition
The inherent long-life characteristics of 70% Hylar® 5000S PVDF coatings outperform silicone-modified performance polyester, polyester, acrylics, plastisols, thick film urethanes, anodized metal, and FEVE coatings.
Hylar® 5000S coatings, blended at the optimal ratio of 70%-30% PVDF to acrylic, maintain their colorfastness and gloss longer than all other architectural coatings. The performance of both Hylar® 5000S-based coatings surpasses AAMA 2605 requirements.

Hylar® 301S is a very fine powder of a crystalline high molecular-weight fluoropolymer ideal for forming chemically and weather-resistant protective coatings on metallic surfaces, fabric, or fiber-reinforced laminates. It is especially suitable for coatings and film casting applications using the organosol dispersion or solution method. It is highly resistant to most environmental conditions including corrosive chemicals and ultraviolet and gamma radiation.
