Anwendung

Verarbeitung

Ambient air temperature

In order to ensure save self-adhesion of the membrane, we recommend a minimum temperature of +10°C during the application. If necessary, the self adhesive membrane shall additionally be activated by welding or torching.

Substrate temperature

In order to ensure save self-adhesion of the membrane, we recommend a minimum temperature of +10°C during the application. If necessary, the self adhesive membrane shall additionally be activated by welding or torching.
