Kynar (PVDF) versus Lumiflon FEVE

Archive of Older Topics Archive - Product Discussions #6

I am reading literature (for alpolic) that states that their Lumiflon FEVE coating is “tested to meet the performance criteria of AAMA 2605”. Also, that Kynar “Meets 2605 but does not offer the high gloss or rich color palette as with Lumiflon”. This leads me to believe that the FEVE does not actually MEET AAMA 2605. Does anyone have any additional knowledge on the comparisons between FEVE and PVDF?

FEVE and PVDF are both fluoropolymers and both meet AAMA 2605 - http://lumiflonusa.com/technical/feve-resins-among-the-top-coatings-in-aama-exposure-tests/

I’d suggest getting samples of both and see which you prefer.

I am doing some market research for my MBA program and have found that FEVE and PVDF are the dominant resins in the fluoropolymer market. Are my conclusion correct? What would be the interest or process of introducing a competitor to FEVE and PVDF?

The resins are used in a wide variety of industries. If you are interested in the architectural coating segment, you are welcome to contact me. Contact info at www.chusid.com.

I have seen that sort of qualified statement before. Typically, it means the product in question may be of different materials, or in some other way vary from the cited reference standard, but that it complies with the performance requirements, or whatever other part of the standard is mentioned. For example, a roofing membrane of reconstituted banana peels might comply with the performance requirements for EPDM, but nothing else.

I’d certainly want some sort of walkway pad on that roof.

Market a roofing membrane of reconstituted banana peels as a membrane and slip sheet in one.

PVDF resins, liquid or powder, must be baked (metal must reach 450F or thereabouts). FEVE is air-dry, and I believe has been in use for years for field touch-up work. My presumption is that FEVE will take over if comparable performance can be achieved without needing to bake.

I believe PPG’s Coraflon is based on FEVE.

Dave - an excellent jest.

  1. Not all PVDF systems must be baked. There are now water-based, air-dry PVDF coatings available.

  2. In typical formulations PVDF resin-based coatings contain higher fluorine levels than FEVE-based coatings, resulting in greater resiliency, color and gloss retention.
