What is Kynar® PVDF?
Kynar® polyvinylidene fluoride (PVDF) is a high-performance engineering thermoplastic known for its exceptional durability, chemical resistance, and weatherability. Used for more than 50 years in architectural coatings, Kynar® provides a long-lasting finish that resists UV degradation, corrosion, and color fading, making it a leading choice for industrial, architectural, and marine environments.
| Property | Details |
|---|---|
| Chemical Resistance | Excellent resistance to acids, bases, halogens, hydrocarbons, alcohols, and oxidants. Suitable for harsh industrial environments. |
| UV & Weather Resistance | Outstanding resistance to sunlight and environmental exposure allowing minimal color change over decades. |
| Mechanical Strength | High tensile strength (5,000–8,000 psi) and impact resistance with low creep under stress. |
| Low Permeability | Provides a reliable barrier against gases, fuels, and moisture. |
| Electrical | High dielectric strength (1.6 kV/mil) and excellent insulation properties. |
