Introduction to PVDF Coatings
Since PVDF is transparent to and unaffected by ultraviolet (UV) radiation, the pigment used in a PVDF coating must be opaque in order to protect the substrate from the sun''s damaging UV radiation. To compliment the stability of PVDF, pigments should also be resistant to heat (since the coating is baked), chemicals and weathering. In general,

PVDF UHP bevat, in tegenstelling tot de standaard PVDF, geen additieven zoals UV-stabilisatoren, weekmakers, vlamvertragers of smeermiddelen. Deze grote zuiverheid maakt PVDF-UHP bijzonder geschikt voor het transport van ultrazuivere media en ultrapuur water. Vervuiling door uitlogen is met een PVDF-UHP leidingsysteem praktisch onmogelijk.
On the Solubility and Stability of Polyvinylidene Fluoride
PVDF is typically 50–60% crystalline, and properties such as density will depend on the extent of crystallinity and the proportion of each crystalline phase formed.
