Benefits/Advantages To Customer

Excellent adhesion and seal: Holds thin-walled fiberglass radome securely in place and provides cost-effective waterand air-tight bond line.

Temperature resistant: Acrylic adhesive resists high temperatures that may be encountered in outdoor environments.

Quick and easy handling: 3MVHBTape is easy to apply with a film liner, eliminating the need for drilling and riveting.

Cleanliness: VHB Tape is clean, eliminating the drilling residue on the Printed Circuit Board (which could distort microwave energy). VHB Tape is cleaner to apply than most silicones.

Helps improve productivity: Using VHB tape in the production process can help improve rates over many typical mechanical fastening methods.
