Watt Density in Corona Treatment

Watt density is critical in corona treatment for the ability to predict results. When you know what watt density is required for your material and your desired results, you can eliminate trial and error and achieve predictable corona treatment results.

FAQ

Watt density is a formula used to determine the density of the corona discharge on your substrate. The variables in watt density are treat width, line speed, treat sides and output in watts. When you know these variables, you can calculate and adjust your watt density for predictable results.

Watt density is crucial because it directly influences the effectiveness of the corona treatment. Too little power may result in inadequate treatment, leading to poor adhesion and product quality issues. On the other hand, too much power can damage the material or lead to issues such as overtreatment. By carefully controlling watt density, QC Electronics ensures consistent, high-quality surface treatment across various materials and applications.

Watt density is used to predict the dyne level or surface energy of the substrate. When users know the required watt density for the dyne level they are seeking relative to the material they are treating, they can program their watt density and enjoy foolproof results. Understanding watt density adds an extra layer of security to the process, knowing you’re getting your required treat levels. This is extra important for applications with a low tolerance for dyne level variances and require precision accuracy.
