FreiLacke - Energy-Efficient Powder Coating System
Energy-efficient powder coatings, also known as low-temperature or fast-reacting powder coatings, are designed to reduce baking temperatures, thus lowering oil and gas consumption during the coating process. These coatings address bottlenecks in production by mitigating oven size constraints and enabling increased throughput speeds. They offer flexibility to a wide range of substrates, including wood materials (MDF), plastic components, and metallic substrates, which benefit from controlled peak temperatures. As a result, these coatings are suitable for heterogeneous component ranges that vary in thickness, reducing the risk of discoloration. The technology not only enhances cost-efficiency and production productivity but also expands the feasible applications in various industries by accommodating components sensitive to higher temperatures. FreiLacke provides an energy calculator to identify potential cost savings and optimize oven settings for specific requirements.
Lower baking temperature – many advantages
The term energy-efficient powder coatings is directly associated with what are known as low-temperature powder coatings or fast-reacting powder coatings (NT). For energy-related purposes, many powder coating processors look for the opportunity to lower baking temperatures, thereby achieving direct reductions in oil and gas consumption. The use of energy-efficient powder coatings is of course beneficial in this respect. However, that is only one reason for using them.
Reduction of baking temperatures in the oven
This results in the direct reduction of oil/gas consumption.
Increase of productivity within the coating system
The baking oven frequently constitutes a bottleneck point in the process. All too frequently, space constraints make it physically impossible to increase the size of the oven. At certain baking temperatures, the line speed can be increased, thereby shortening the oven throughput time.
Expansion of the component range
When the component range is very heterogeneous, e.g. ranging from very thin to very thick components, the risk of discolouration can be reduced substantially by reducing peak temperatures to create less intensive baking conditions.
Opening up new fields of application
These can, for example, take the form of wood materials (MDF) or plastic components. In addition, this process can also include other metallic substrates which cannot, for functional reasons, be exposed to any higher temperatures, or fully assembled modules which are also subject to a limit on peak temperatures.
