Paint Types offered by Linetec
|
|
Linetec presently offers a variety of architectural
paints ranging from 70% Kynar 500®
and Hylar 5000®
which meets AAMA 2605 specification, 50% Kynar®
and Hylar®
meets AAMA 2604 and Baked Enamels
which meet AAMA 2603. The AAMA 2605 is a high performance
specification made for organic coatings for architectural and heavy
commercial applications. The AAMA 2603 is the lower performing
specification that is typically used for interior architectural,
residential or very light commercial applications. For specific
performance details see our
Finish Performance Comparison,
comparing both paint and anodize systems.
PVDF
or 70% & 50% Kynar®
and Hylar® coatings:
PVDF
non-metallic, non-exotic colors generally require a two-coat process
(mica colors may also fall into this category). Specialty exotic and
metallic colors generally have a three or four coat process. Three
coat meaning primer, topcoat and clear. Four coats include primer,
barrier coat, topcoat and clear.
PVDF
coatings are the most weather resistant of all finishes. These
coatings are also called fluorocarbon, fluoropolymer, and trade names
of Kynar 500®
and Hylar 5000®. Some of the characteristics
these types of finishes exhibit are outstanding resistance to
humidity, color change, chalk, gloss shift and chemical cleaning;
these types of finishes meet or exceed all criteria of the AAMA 2605
specification.

Coraflon EX (formerly Megaflon EX)
Coraflon EX (formerly Megaflon EX) spray-applied extrusion coatings
provide a colorful, high-gloss, automotive-quality finish. Coraflon
not only meets all AAMA 2605 standards for PVDF finishes, but are also
available in a palette of rich, vivid colors and a full range of
glosses from satin to high luster. Coraflon EX coatings offer
excellent adhesion to aluminum substrates. These characteristics make
them an ideal choice for high-profile architectural applications where
long-term aesthetics are desired. |

Baked
Enamel coatings:
Baked
Enamels are generally a one-coat process as no primer is required. In
this process the top-coat is applied directly to the material.
The
characteristics of Baked Enamel coatings are different than that of
PVDF coatings. Baked Enamel coatings are used primarily for interior
applications where color retention, chalk, fade and weatherability is
not required. While these coatings are much harder and more more
resistant they do not have the weatherability of PVDF coatings. These
coatings meet or exceed the specifications of AAMA 2603.
Paints applied at Linetec can be considered either Exotic or Non
Exotic. Exotic colors are “ non-earth tone” colors. These colors quite
often require a clear coat for pigment protection. Exotic colors are
not in-house blendable. Non-Exotic would be earth tone colors, which
are often blended in-house. |

Mica and Metallic Coatings
Linetec specializes in the
application of specialty paints like metallic and mica coatings.
Paints containing metallic or mica pigment will show some
variation in appearance. Getting the metallic or mica flake to lay
just right for color consistency is dependant on many variables,
some which can be controlled while others like material shape can
not.
Color Consistency and
Clear Coats
In
order to ensure color consistency, it is important that material
is painted in as few releases as possible. Bright or clean whites
also tend to have issues in maintaining color consistency, as they
require a high dry film thickness in order to maintain their color
consistency. Linetec is able to reduce the color variation by
applying a base coat underneath the top-coat to build film to
easier achieve hide and color consistency. Clear coats are
normally required for exotic and metallic finishes to protect the
pigment from the sun. Clear coats are not really clear, when
putting a clear coat over a light color it will change the color
giving it a yellowing appearance. Applying a clear coat to a
finish not requiring a clear not is not recommended.
Spattercoat
Linetec also specializes in the application of a spattercoat
process. Spattercoat is achieved by first painting the under coat
color over the entire exposed surface. the material is then
spattered with the remaining color to give it a 3D effect. The
material may have a marbled or brick like appearance.
Two-Tone Painting
One
of the many services provided by Linetec is two-tone finishing,
the process of painting one side of the material one color then
masking it off and painting the other side a different color.
The
following criteria apply to two-tone orders. Please contact
Linetec to review your two-tone requirements
- Linetec can provide two-tone
finish for extrusion material
- Flat
sheet can be two-tone finished on the separate sides,
however we do not two-tone finish just one side
- Contact
Linetec quoting department for information on material
types other than extrusion
-
Different paint types may not
be compatible on the same profile
- Both
paints require equal baking temperatures
- When
paints bake at different temperatures, one color risks
burning, peeling, and / or discoloration
-
Two-tone finish may not be
warranted if the paints are from different vendors
- Dimensioned die drawings are
required, which specifically indicate the interior and exterior
exposed surfaces
- Linetec cannot guarantee a straight line for split finish when
colors are touching
