A. PVDF coatings are made of PVDF fluoropolymer resin and inorganic ceramic pigments. They are coated on aluminum and steel for architectural buildings and can last decades without coating chalk or obvious color change. PVDF coatings are considered as most durable coatings so far. There are several types of PVDF coatings: coil PVDF coatings, liquid PVDF spray coatings and powder PVDF coatings. Only few coatings companies supply PVDF coatings since all PVDF coatings suppliers must obtain application license from PVDF resin suppliers of AtoFina and Solvay who are the only two suppliers of PVDF resin with trade name of Kynar 500 and Hylar 5000. PPG, Valspar, Rohm Hass, Akzo are main liquid PVDF coatings suppliers. Rohm Hass and FineShine are main PVDF powder coatings suppliers. You can find detail product information from their web site.

A. PVDF is ~~PLOY~~^^POLY VINYLIDENE ~~fluoridE~~^^FLUORIDE
These are chemical resistant coatings primarily used on chemical processing equipment. Other application are applied to Glass/ Metal and other exterior materials.

I think PVDF expansion is not "PLOY VINYLI DENE fluoridE", it could be POLY VINYLE ----- FLUORIDE, since all these resins are made out of polymers (C H bonding). I am not sure about the 3rd word, that is expansion of alphabet "D".
One of the above answers say it is DENE, what does DENE stands for...?

Thanks, Jothykumar. We have corrected the typographical errors in the spelling of "poly" and "fluoride" in the earlier letters. Advances in Organometallic Chemistry explains "vinylidene" on page 62 (in Volume 22), under the heading "Nomenclature", as meaning C=CRR' (you may be able to view that paragraph via books.google.com)
