PVDF (Polyvinylidene
Difluoride)
DESCRIPTION
PVDF (also
known as PVF2) is a very high performance, Premium
Architectural Fluoropolymer Coating containing 70% KYNAR
500. It is a thermoplastic polymeric barrier coating
designed to protect aluminium substrates which are
exposed to extremely harsh climatic conditions. The
combination of pigmentation and formulation provides
long lasting beauty, durability and excellent film
flexibility. An 8-stage chromate pre-treatment ensures
optimum coating performance under all environmental
conditions.
PVDF is extremely resistant to
chalking, Ultra-violet deterioration and is supremely
colour-fast. PVDF meets or exceeds AAMA 605:2
specifications covering high performance organic
coatings on architectural aluminium extrusions and
panels. PVDF is available in any colour, including
Exotics, in a choice of matt, gloss and metallic
finishes.
APPLICATIONS
PVDF is particularly suited to
protecting aluminium extrusions, panels and components
where exposure to high levels of UV, salt spray, high
humidity, acid rain, industrial pollutants and high wind
levels can be expected. Its high matrix, thin film
characteristics and excellent wrap features make it an
ideal choice for applying to thin sections where edges
and corners require coverage.
