One common problem during a conformal coating application is the cobwebbing effect. Cobwebbing is the application defect where you see strands or wisps of dried coating floating around the immediate area where the coating is being applied. This defect can have dire consequences in your application leading to failure in the field. This video along with the additional resources such as our blogs/videos mentioned below, you will be able to make to identify these issues early on and be able to rectify achieving excellent results. We have a robust content library that can help you deal with this issue.
