How is PVDF Coating Done?
adv. 
Q. Please let me have the details of the easiest & cheapest way to get the PVDF coating on aluminum sheet and m.s. sheet. I am interested in architectural & industrial coating suppliers.

A. PVDF can be applied to the surface in three ways:
- Solvent copolymers are dispersed in a semi-solvent. Dissolved in a unpleasant solvent (dimethyle acetamide solvent)
- Fine powder used for dip coating
- & electrostatic coating.

Q. Send me all basics to consider related to PVDF coating in various materials mainly ACP. Key points of base coat selection, colour coat procedure, various machine settings, speed settings, and material/square area paint calculations, etc. SP Suresh Kumar- Dubai,UAE

A. Hi, Nitin; hi, SP; welcome to the forum, cousins. PVDF means Polyvinylidene Fluoride, a thermoplastic fluoropolymer. Our readers are generous in trying to help, and well-formed questions are usually answered . . . but please try to be a little bit realistic, folks :-). What you are looking for would require a multi-day training course or a 150-page book. You can't invest 15 seconds of effort on your own behalf posting such broad questions, and then expect a stranger to spend half a week trying to help you. It's not going to happen :-) Please go to your library and obtain a few books about PVDF coatings to get a general introduction to coating procedures, machine settings, area calculations, material selection, etc., and then post any detailed questions in terms of your own experience with the process, or anything that the books failed to mention, and I'm confident you'll get help. Best of luck. Thanks! Regards,

Q. Hello!
I need some info on the PVDF coating, I have a requirement where the aluminium panel has to be coated with PVDF. But the standard Aluminium panels available in the market is Polyester coated.
Kindly let me know which is better?
Does the polyester coating consist of some percentage of PVDF? and how do you compare PVDF with Polyester coating?

A. Hi, Abdul.
Sorry, but PVDF is fluoropolymer and is "better". Architectural sheet metal that is painted with Kynar or Halar (two brand names) is typically guaranteed for 10 to 20 years -- far longer than when painted with polyester powder coatings.

Q. Can you tell me the difference between PVF2 paint finish and PVDF finish?
Hugh Mackay- United Kingdom
A. Hi Hugh.
They are the same thing. My understanding is that PVF2 is just an acronym that came from the chemistry field rather than the coating field.

Q. Which process is longer lasting on Steel: Plating or PVDF coating or Powder coating?
Is there a process called Metal Patination? If so is it similar to plating?
- Doha Qatar
^- Privately contact this inquirer -^
A. Hi Alwyn. "Metal patination" is possibly a bit vague, but in general it probably means to apply a "patina" (an aged look) to the metal. For example, if the item is copper, to apply a coating that either ages the copper by causing it to form some copper salts, or which includes a copper salt. The term usually applies more to copper, brass, and bronze than to aluminum or steel.
Plating means to apply a metallic coating via electrodeposition. There are many metals and alloys that can be plated, but it would be rare to expect plating to last as long as a good paint job. As already mentioned, PVDF is an expensive and long lasting coating. I hate to use the word "better" because everything depends on the situation, but PVDF is more expensive and usually longer lasting than other paints.

Q. The application of majoon / putty to cover welding joints has no effect or reaction in applying PVDF coating? Is it possible? Will there be a shadow effect afterwards?
