When it comes to protecting structures and products made of galvanized steel, the requirements for durability, appearance and sustainability have increased significantly. In response to this trend, Axalta has developed the highly efficient Alesta AP Qualisteel powder coatings in architectural quality. Thanks to product-specific properties, the coating can be applied without a pre-degassing step. Compared to a traditional two-step process application, the use of the new powder coating enables an increase in productivity without affecting the appearance of the coated surface. The high yield and reduced curing temperature also contribute to improved value creation for contract coaters and in-house coating companies. Depending on the substrate to be coated, the coating can be cured at as low as 160 °C, while productivity can be further increased at higher temperatures.

High UV and humidity resistance

The very good UV and humidity resistance in accordance with Qualisteelcoat specifications and excellent mechanical properties extend the durability of coated parts. In addition, the label-free and low-consumption powder coatings, which are available in a wide range of RAL-based colours, provide a more sustainable coating. The coatings are typically used for coating steel structures, machine components, garden and outdoor furniture, fences, railings, playground equipment or lighting elements.
