Infiana and AkzoNobel Enter Cooperation

German specialty films manufacturer Infiana and AkzoNobel, the leading producer of paints and coatings, have entered a cooperation. Focal point for this exclusive partnership will be the release film technology FlexPLAS and its applications for composites production in the wind power industry.

The collaboration between specialty films manufacturer Infiana and coatings specialist AkzoNobel allows for qualitative improvements in surface texture during wind turbine blade production. “Our testing has returned above-average results. Combining coating and film in the manufacturing of blade components creates an optimization in the production process,“ notes Markus Stieglbauer, Global Business Manager Industrial Coatings at AkzoNobel. “Beyond the improved surface quality, there is also a reduction in process costs and lower environmental impact. The complex grinding and filling processes needed to activate the part’s surface are eliminated and coating weight can be further optimized,“ explains Soheila Salehi-Schneider, Project Leader FlexPLAS at Infiana.

Significantly Shortened Production Time

In wind turbine manufacturing, process lacquer and topcoats are applied to turbine blades as lasting protection for the blade, as well as for optical reasons. Applying these lacquers is a complex process. First, all release agents must be removed from the cured component through cleaning, grinding, and filling before any lacquer can be applied. After this, gelcoats are applied in a series of layers. At the same time, the mold must be cleaned to prepare it for the next part. This is where the new technique comes in: by applying the gelcoat directly to the FlexPLAS release film after it has been deep-drawn in the mold, the coating can be cured alongside the part in just one process step. “The advantages are obvious: relevant process times are reduced by up to 60 %, the overall risk of coating defects is noticeably lower, the process becomes more environmentally friendly, and workplace safety is increased,“ adds Salehi-Schneider.
