White & Silver Duranar coil coatings
Duranar high-performance fluoropolymer coil and extrusion coatings are designed
to provide outstanding aesthetics and durability in a wide range of architectural
uses under normal environmental conditions. The coatings combine PPG proprietary
resin and pigment technologies, with 70% of the resin system consisting of Kynar
500® or Hylar 5000® base resins.
Duranar coil and extrusion coatings exceed the industry’s toughest performance
specifications, including AAMA 2605. The coatings are chemically inert, providing
outstanding resistance against color and gloss fade as well as environmental
stress such as acid rain and ultraviolet attack.
Duranar coil coatings are roll-coated and oven-cured on automated paint lines
and are approved for use on properly cleaned and treated aluminum and coated
steel substrates such as G90 hot dip galvanized, Galfan®, Galvalume®
and Zincalume®. Coil-coated end-use products include roofing panels, siding,
column covers, gutters, downspouts, soffit, fascia and trim. Duranar coil coatings
are applied at a very consistent dry film thickness, which offer flexibility
for post-formed applications and long-term durability.
Duranar extrusion coatings are spray-applied and oven-cured on automated paint
lines and are used to coat aluminum extrusions and other pre-formed aluminum
components. Spray-coated end-use products include window frames, louvers, skylights,
curtainwalls and storefronts. Final color approval should be made from actual
production line samples, not laboratory-prepared samples. Range samples should
be requested from the applicator for metallic and mica-containing colors, as
well as for bright whites.
The basic 2-coat system consists of a patented primer and a durable color coat
that is recommended for use in normal environments when added protection against
industrial or seacoast environments (corrosive chemical, salt spray, etc.) is
not required. This 2-coat system is very resistant to fading, chipping and peeling
when properly applied by an applicator. Duranar coil and extrusion coatings
resist dirt collection and chemical staining, and can significantly reduce maintenance
costs over time. Duranar LG, a low luster, matte clear coat finish is also available
for use on Duranar coil and extrusion coatings where non-glare is required or
desired.
Duranar Sunstorm extrusion coatings are a 2-coat system consisting of a patented
primer and a durable color coat containing mica pearlescent flakes. Duranar
Sunstorm coatings provide a metalescent look without the use of aluminum flakes,
which require a clear topcoat. This 2-coat system combines value, durability
and brilliant appearance. PPG currently offers a variety of colors ranging from
white pearlescent to copper, silver and gold.
Duranar XL clear extrusion coating is an essential component of the 3-coat
system, which consists of a primer, a durable color coat and the XL clear topcoat.
The 4-coat system requires a barrier coat between the primer and color coats
when the color contains certain aluminum flake pigments. The XL clear topcoat
is also required over some brightly pigmented Duranar coatings and all colors
containing metal flakes in order to protect against UV, humidity and chemical
attack. For added protection, the XL clear topcoat may be specified over any
Duranar coating to improve the overall performance and ease of maintenance of
the finish system.
Duranar Plus coil coatings are 2-coat, thick-film systems designed to provide
outstanding aesthetics and durability in a wide range of architectural uses
under aggressive environmental conditions. They are ideal for applications requiring
greater flexibility as well as abrasion and corrosion resistance. Because the
system requires only one pass through a tandem coil coating line, it provides
an economical alternative for buildings facing more aggressive environments.
Duranar Plus coil coatings require minimal maintenance and minor scratches can
be easily repaired in the field.
Duranar XL Plus coil coatings are 3-coat systems based on a patented PPG urethane
primer that imparts exceptional adhesion plus excellent abrasion resistance,
maximum flexibility, chemical resistance and barrier corrosion protection. These
enhancements make Duranar XL Plus the best choice for applications that must
endure highly aggressive industrial and seacoast environments.
Duranar XLE coil coatings are 3- or 4-coat systems that not only offer excellent
abrasion resistance, flexibility, chemical resistance and barrier corrosion
resistance, but provides reliable architectural finishes in bright, exotic accent
colors and true metallics not possible with other formulations. The clear topcoat
protects the color coat from atmospheric pollutants and enhances its durability.
The barrier coat (4-coat system) provides excellent UV protection for the primer.
Duranar 2000 (2-coat), Duranar 4000 (4-coat) and Duranar 5000 (4-coat) coatings
are multi-coat, thick film systems that provide exceptional aesthetics and durability
in architectural applications where the additional protection provided by thick
film coatings is desirable. The extra film thickness of these coatings provides
outstanding barrier protection, corrosion resistance, chemical resistance and
toughness.
Duranar SPF IR reflective coatings are multi-coat systems designed to provide
outstanding aesthetics, durability and long term IR reflectivity in a wide range
of uses. They are designed to comply with the ENERGY STAR® solar reflectance
limits established for steep-slope or low-slope roofing products. The cooling
effects of Duranar SPF coatings will offer potential benefits such as reduced
air conditioning costs for commercial and residential construction, less product
expansion and contraction, plus improved comfort levels for building occupants.
These coatings offer architects and designers more color options for metal roofing
since they are available in a palette of medium to dark colors, as well as light
colors.
A 20-year non-transferable warranty on all Duranar coil coatings is offered
to approved coil coaters or metal building component manufacturers within North
America. A 20-year non-transferable warranty is offered to ‘warranty-approved’
applicators of the Duranar factory-applied spray coatings within North America.
Express or implied warranties regarding particular performance characteristics
for specific applications are the responsibility of the coater or applicator.
A list of approved coil coaters and spray applicators is available upon request.
