ALUM*A*STAR™ 50 is the newest of Akzo Nobel's extrusion coatings. As its
name indicates, ALUM*A*STAR®™ 50 contains 50% of the same PVDF KYNAR® or
HYLAR® polyvinylidine fluoride resin used in Akzo Nobel's TRINAR® line of finishes.
Their chemists have developed a truly unique system known for its ability to
meet and exceed the new AAMA 2604-98 Specification for High Performance Organic Coatings on Aluminum Extrusions and Panels. Some of the
beneficial and desirable features of this new system
- Application excellence
- Adhesion to properly prepared aluminum
- Hardness characteristics.
These features, coupled with the extraordinary weathering and durability in the field, make ALUM*A*STAR™50 not only
an excellent choice for many outdoor applications, but a great alternative to some of the currently offered interior finishes on large curtain wall projects. ALUM*A*STAR™50 is available in a non-exotic color palette.
If you want a great High Performance PVDF-containing coating but wish to

End Use Description
ALUM*A*STAR 50 is a Fluoropolymer
(PVDF) system that contains 50% KYNAR® or HYLAR® resin. This exciting
new technology was designed to offer a less costly alternative to 70% PVDF
systems for application on aluminum for low-rise and mid to light commercial
curtainwall and storefront construction, high-end clad window systems,
transportation products and other miscellaneous "High Performance"
construction products. See
ALUM*A*STAR™ 50 Performance Properties
(opens in new window) specification for more information.
ALUM*A*STAR50 has the following beneficial
- High Performance in a variety
of normal climatic conditions
- Ceramic/Inorganic pigmentation
for superior color and gloss retention
- Cost Advantages
- Batch-to-batch consistency
- Beautiful color selection
- Long-life durability
ALUM*A*STAR™ 50 is strictly spray-painted because the intricate
profiles of extruded aluminum require spray application. This ensures that
the proper thickness of the coating is evenly applied to the channels and
recessed areas of the extrusions.
The coating is applied only after the
metal substrate is properly cleaned and chemically prepared in accordance
with the manufacturer's instructions. The coating is then applied to the
metal and baked.
ALUM*A*STAR™ 50 is a two-coat system baked to manufacturer's specified
peak metal temperature. Color, gloss, hardness, cure, flexibility, adhesion
and other checks are conducted during on-line Quality Control.
Test methods are established by ASTM (American Society for Testing and
Materials). The most recognized specification for "High Performance" is the
American Architectural Manufacturers Association "AAMA 2604-98." It is a
FIVE-year specification called Voluntary Specification, Performance
Requirements and Test Procedures for "High Performing Organic Coatings on
Aluminum Extrusions and Panels." See

ALUM*A*STAR 50 is made with a licensed fluoropolymer
resin technology and a proprietary acrylic co-polymer in a 50/50 blend.
This resin combination forms the strongest molecular bond in the coatings
industry. The PVDF resin is manufactured by two companies; ATO-Fina Chemicals
(KYNAR®) and Ausimont USA (HYLAR®). Only the finest quality ceramic/inorganic pigments for a wide range of colors and superior color retention
are used in concert with this unique resin combination.
Proper maintenance is vital for any coating to achieve
maximum installed life performance. Contact Akzo Nobel and ask for a copy
of our "Care and Maintenance" Guide for recommended methods and procedures.
Color matched air-dry coatings for post-construction touch-up and scratch
repair are available for all Akzo Nobel building products finishes through
Superior Metal Technologies (SMT). These repair kits should be specified in the architect's
