For durable, architectural aluminum building components, the industry most often relies on two types of finishes: anodize and paint. Both offer a long-lasting finish, but each has its own characteristics inherent in its application. As an architect, specifier, contractor, or other member of the building community, this presentation will help to better understand weathering performance and sustainable goals of architectural fluoropolymer (Kynar) paints, baked enamels, powder coating and anodize finishes including strengths, weaknesses, weatherability and environmental considerations. Anodize, paint and powder coat application processes, specifications and performances are explained, and a summary comparison of all three finish types completes this presentation.
1. Learn about anodizing's electrochemical process and how it converts the aluminum surface to an extremely durable, corrosion-resistant finish for architectural building products. The strengths and limitations of this fully integrated, non-hazardous finish are discussed and supported with specifications for achieving optimal results.
2. Review the powder coating process and how it compares to, and differs from, the liquid paint process. The strengths and limitations of powder coating for architectural aluminum building products are discussed and supported with specifications for achieving optimal results.
3. Compare anodize, liquid paint, baked enamel and powder coat finishes for architectural aluminum building products to achieve optimal results. Referencing AAMA specifications, the program reviews weathering performance characteristics, warranty expectations and initial cost considerations for each of the finish types
4. Discuss the painting process and its application as a protective, decorative organic coating for architectural aluminum building products. The program describes high-performance fluoropolymer coatings (including Kynar 500.) and baked enamels, and how a quality finish is achieved in each type. Strengths and limitations, including environmental and performance considerations, also are discussed and supported with specifications for achieving optimal results.
