AkzoNobel has announced the availability of a new silicone-modified polyester coating solution for aluminum. Designed for spray application to aluminum, CERAM-A-STAR E is a new solution with proven durability and ease of application that meets American Architectural Manufacturers Association (AAMA) 2604 specifications, according to the company. Designed for the high-end residential, storefront and monumental interiors market, this product offers a lower-cost alternative to 50 percent PVDF and super durable polyester powders. Further, as compared to anodized solutions, it offers better quality, more consistent color control and options, chemical resistance and field repairability.
Building on the performance of the CERAM-A-STAR family of silicone-modified polyester (SMP) coil coatings, this new product has been adapted to serve the unique needs of the aluminum extrusion industry.
CERAM-A-STAR E was developed from a proven coil coating product with millions of square feet already installed in the field. The modifications for spray application preserve these well-established performance characteristics. CERAM-A-STAR E was developed in response to the market need for a universal aluminum coating system.
CERAM-A-STAR E’s proprietary resin formulation is the pillar for this SMP system. Combined with premium ceramic and inorganic pigments, it offers superior color stability, chalk resistance, fade resistance and gloss retention for the most durable AAMA 2604 finish available.
Although this product is just being launched at-large for the fenestration market, the AkzoNobel reported that the product was recently tested in the Middle East with favorable results.
Multiple colors and finish options were evaluated, and all met the level of durability that is called for in AAMA 2604. In addition to its proven durability, CERAM-A-STAR E has a number of other benefits that customers will find very appealing. The maximum achievable volume solids of a 50 percent PVDF coating are usually 26-28 percent, however, users can achieve 48-54 percent volume solids with CERAM-A-STAR E.
The company reports that it is also a good fit for the just-in-time production environment of today. The ability to perform quick color changes during production is a big help in maintaining an optimal production schedule. It also allows coaters to blend colors in-house, including mica metallics, which isn’t possible with other effect technologies.
