dam fill ab chimieIf very thick layers of protective varnish are required or if the flow of the applied varnish must be prevented, e.g. to prevent penetration into plug contacts, then a dam can be formed with a highly thixotropic material. The dam is applied as a bead with a dispensing system. Behind this dam, the more liquid protective varnish is then filled up to the desired application thickness.
