COATING TECHNOLOGY
SUSTAINABLE COATING OF GALVANISED STEEL
steel offers benefits that coaters have been looking for. Excellent degassing properties and a good flow ensure a superb surface appearance. The fast and reliable curing at low temperatures enables energy savings and an increase in productivity. Very good UV and humidity resistance according to Qualisteelcoat specifications provide longer life cycles of coated parts. Additionally, Axalta Coating Systems’ new label-free and low consumption powder coatings, which are available in a wide range of RAL based colours, make coating more sustainable.

When it comes to protecting galvanised steel structures and products, the demands for durability, appearance and sustainability have increased significantly. In response to this trend, Axalta offers the highly efficient Alesta AP QualiSteel powder coatings in
he innovative powder coating Alesta AP QualiSteel for the coating of hot dipped galvanised
architectural quality. Thanks to innovative 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, Alesta AP QualiSteel can be cured at as low as 160°C, while productivity can be further increased at higher temperatures. In addition to the material and energy savings, the new powder coatings have hazardous label free formulations.
The powder coatings also offer very good UV stability and mechanical resistance, leading to a longer life cycle of the components. Alesta AP QualiSteel is typically used
for applications such as coating steel structures, machine components, outdoor lighting and more. l

COATING TO TACKLE ENGINEERING CHALLENGES P
oeton Industries has recently launched Apticote 480A, a new composite coating that combines
the properties of nickel and fluoropolymer materials into one problem-solving solution.
The treatment has been created in the Poeton R&D Laboratory led by Dr John Archer and builds on the success of existing nickel-polymer treatments. Apticote 480A has been designed to
support engineers who are tasked with driving constant improvement and solving engineering challenges. Whether that be material wear and corrosion or to implement improved efficiencies, increased output or cost reduction, the new coating that can be used to tackle all of these challenges.
Apticote 480A can be applied to a variety of base materials and demonstrates superb properties, such as a coefficient of friction as low as 0.05. This is 90% lower than a standard heated treated electroless nickel coating and provides a host of benefits including reducing energy and torque requirements in both sliding and turning applications. The coating also delivers excellent non-stick properties, making it the
ideal choice in mould release applications in the food, medical and pharmaceutical production sectors. Using Apticote 480A ensures that the products can be removed easily from their moulds and less contaminants will remain in the mould, reducing clean-up costs and ultimately increasing production speeds. The coating also excels in resisting the
effects of adhesive wear, which causes surfaces to quickly damage and eventually resulting in parts seizing. Its low friction properties reduce adhesive wear by 85% when compared to standard heat treated electroless nickel. For engineers, this not only means a reduced chance of seizing but also allows for lowering the number of in-service inspections and less machine downtime. l
