Wasco offers a variety of architectural paint colors in 70% Kynar 500® PVDF resin-based coatings which meets the AAMA 2605 specification, and baked enamels which meet AAMA 2604. We also offer various anodized coating colors that meet AAMA 611 Class I specifications. Copper cladding is also available.
Overview
Kynar 500 – Meets AAMA 2605
70% PVDF (Kynar 500®) resin-based coatings offer the ultimate protection in building performance. These finishes exhibit outstanding resistance to humidity, color change, chalk, gloss loss and chemicals. These sustainable coatings will ensure a long-lasting, durable finish. No other coating system can withstand the rigors of nature and time like those based on the Kynar 500 resin. 70% PVDF resin-based coatings include standard color two-coat systems, consisting of a primer and color coat.

Baked Enamel – Meets AAMA 2604
Baked enamel coatings are harder than PVDF coatings and are often used for interior application where color retention, chalk, fade and weatherability is not required. Baked enamels are generally a one-coat system as no primer is required. In this process the color coat is applied directly to the aluminum.

Anodized – Meets AAMA 611 Class I
Anodizing is the process of electrochemically controlling, accelerating and enhancing oxidation of an aluminum substrate. The anodizing process, because it is an integral part of the substrate, produces an oxide film that is uniform, hard and protects the rest of the aluminum substrate from deterioration – providing excellent wear and abrasion resistance with minimal maintenance in most environments.
The coating produced is extremely durable, and the hardness of the surface is comparable to a sapphire—the second hardest substance on earth. This characteristic makes anodize an excellent choice for use in high-traffic areas where resistance properties are important.
Anodized aluminum resists the ravages of time, temperature, corrosion, humidity and warping, adding to it’s long life cycle. Anodized aluminum is an inert material that is not combustible, 100% recyclable and poses no health risks.

Strengths & Limitations
| Strengths | Limitations | |
| Kynar 500 | Color Retention (UV resistance)
Salt-spray resistance Vast array of color choices Paint protects and maintains the structural integrity of the aluminum Field touch-up / repainting capabilities Small-batch and custom color capabilities – fast and cost effective |
Fair hardness
Cost of high-performance products Potential for inconsistent appearance of “metallic” paints Solvent based paints are not environmentally friendly without an oxidizer |
| Baked Enamel | Environmentally friendly
Hardness and abrasion resistance Vast array of color gloss and texture options Paint protects and maintains the structural integrity of the aluminum |
Warranty – generally more limited and restrictive than liquid Kynar®
Metallic Coating – cannot hold as much metallic flake content Touch-up and field repair Small custom color jobs are not cost effective due to minimum batch size No in-house blending of powder coat. Longer lead time for samples and color matching |
| Anodized | Color stability
Hardness, compared to a sapphire Durability, abrasion resistance Anodize protects and maintains the structural integrity of the aluminum Ease of maintenance |
Limited color choices
Difficult touch up Color may vary depending on alloy & trace elements in aluminum Surface imperfections of the aluminum may show through the anodize |
