About PVDF paint for roofing

++++++

I am in a company that uses prepainted roofing. I would like to ask for the meaning of PVDF paint and how it differs with polyester and other paints?

Hi Nicanor,

Paints are nearly never as good as the original 'solid' product unless this is a 2 component paint ... like the 2 component Urethane, which is expensive.

PVDF itself is extremely acid resistant and resists alkalines upto pH l0.

The other thing you have to consider is UV resistance ... and I'm not sure about PVDF but it is a less permeable material than fibreglass and unless the roof panels were made of a thick frp (+ glass), it'd probably last longer.

My background was in the 'solid' (never paints) thermoplastic materials.
