Hylar® 301F PVDF for Coatings
Hylar® 301F PVDF is a versatile engineering plastic with a balance of physical properties that qualify it for high performance service in a wide range of applications.
Performance
Hylar® PVDF coatings possess the characteristic stability of fluoropolymers when exposed to harsh thermal, chemical and ultraviolet environments.
Key features
- Stability at temperatures up to 316°C
- Excellent chemical resistance
- Excellent weather resistance
- Suitable for coating of metallic and fabric or fiber reinforced laminates
Processing
Hylar® 301F PVDF is used to produce a dispersion coating that can be applied to metal substrates and baked at high temperatures to produce a smooth film.
Applications
Hylar® 301F is a high melt viscosity PVDF grade for non-architectural coatings such as chemical process equipment, automotive underbody, fasteners and brake tubes applications or for industries where exposure to highly corrosive chemicals and elevated temperatures is standard.
