Application Guidelines
Ensure the surface is clean, dry, and free of grease or oil before applying the tape.
Apply with sufficient pressure to maximize adhesive contact.
Bond strength improves with increased dwell time.
Different surfaces (film or rigid) and environmental conditions (temperature and pressure) can influence adhesive performance.
Suitable for both manual and automated application methods.
Storage & Shelf Life
Shelf life: 2 years from the date of manufacture when stored at
64-72°F (18-22°C)
30-70% relative humidity
Store tape in original packaging, away from direct sunlight and contaminants.
