Application Guide
-
Surface Preparation: Ensure surfaces are clean, dry, and free from dust and debris.
-
Primer Application: Apply Gerband 6300 Primer evenly on the surface to be bonded.
-
Drying: Allow the primer to dry thoroughly—the surface should feel mostly dry.
-
Multiple Coats: For difficult substrates, apply several coats, allowing each to dry completely.
-
Tape Application: Press adhesive tape firmly onto the primed surface immediately after drying. Follow the tape manufacturer’s instructions for optimal bonding.
-
Processing Conditions: Apply at temperatures between +5°C and +35°C.
