Coatings for Any Environment

Whether you’re in an extreme weather location where the sun’s UV can cause significant degradation and damage, or in highly corrosive locations like coastal areas or aquatic facilities, the finish you choose can have a huge impact on the longevity of your daylighting system.

Paint & Anodize Finishes – Overview & Warranties

Major Industries offers a wide range of finish options and color choices for your daylighting system. Whether you’re interested in a clear anodize finish or a custom-matched Kynar® color, we’ll work with you to find the best option for your project.

Kynar® high-performance architectural fluoropolymer coatings (PVDF resin-based coatings) offer excellent color retention, salt-spray resistance, simple field touch-up and repainting capabilities and a vast range of color options. Major offers two paint options, meeting AAMA 2604 and 2605 specifications.

  • 50% Kynar® / AAMA 2604 – High Performing Finishes – Standard 5 year warranty and optional 10 year warranty
  • 70% Kynar® / AAMA 2605 – Superior Performing Finishes – Standard 10 year warranty and optional 20 year warranty

Major also offers a wide range of anodize finish options. Anodizing is the process of electrochemically controlling the oxidation of an aluminum substrate, creating an extremely hard, durable and attractive coating. Architectural anodize finishes also provide a hardness and scratch resistance that surpasses that of paint coatings.

  • AAMA 611 Class I Anodize Finish – Anodize finishes offer a standard 5 year warranty and optional 10 year warranty, and can provide some cost savings over similar Kynar® finishes. See image below for standard anodize color options.

See below for our standard Kynar® and Anodize finish color option chart (custom Kynar® colors and color-matching also available). For more information on finish options available for Major’s daylighting systems, or to request physical samples, email us at or call 888-759-2678.

Finishing In-Depth – A Major Advantage

Pre-treatment and Pre-planning
It’s important to consider that one of the best defenses against paint failure is proper pre-treatment of the aluminum, as premature failure of the finish is almost guaranteed without it. Make sure your daylighting provider works with finish partners that understand how vital these preparatory steps can be.

When selecting paint options for corrosive or extreme environments, make sure to specify high-performance 70% PVDF (polyvinylidene fluoride) coatings (Kynar®), as they’re required to perform to rigorous testing performance standards, including more than 4,000 hours of salt spray, and heat-and humidity-resistance to meet AAMA specifications. Kynar®/PVDF coatings are also available in a 50% option for more “standard” environmental conditions. These finishes are available in both standard and custom colors and also shield the building against weathering, pollution and aging. That’s because the carbon-fluorine bond used in Kynar®/PVDF coatings is one of the strongest known, supporting long-term color and gloss-retention and chalk-resistance, even under intense UV radiation.

When extreme hardness is required for aluminum building components, an anodized aluminum finish is a great option. Besides coming in both clear and a range of color options, the hardness of anodized aluminum rivals that of a diamond (on the Moh scale of hardness, a diamond is 10 and anodized aluminum is 9).

Architectural anodize is specified for its natural beauty, but also for its long life and low maintenance. It provides excellent wear and abrasion resistance with minimal maintenance in most environments, and it resists the ravages of time, temperature, corrosion, humidity and warping. A limited number of color choices are available, including clear, various shades of bronze, and some newer colors that mimic the look of copper and even a darker red shade.

Cleaning and Maintenance
Of course it’s also important to take care of your system’s finishes once installed. Studies show that atmospheric pollution can have a negative effect on finish longevity, and runoff from adjacent site materials like mortar, cement and even gypsum dust can accumulate as alkaline deposits on aluminum surfaces and must be promptly rinsed. While somewhat more resistant to alkaline attack than anodized surfaces, high-performance paint finishes can be damaged by rough attempts to remove buildup.

There’s no doubt that corrosion of architectural aluminum materials is a concern, but by taking the proper steps and preventative measures to minimize the potential for its occurrence, you can preserve aluminum’s intended look, reduce replacement costs and conserve resources.
