Tape 4941F

Application Method

Typically done manually.

Key Application Requirements

Seal, adhesion, UV and moisture resistance.

Product Replaced

Rivets or other mechanical fasteners.

Benefits/Advantages To Customer

Excellent adhesion and seal: Holds thin-walled fiberglass radome securely in

place and provides cost-effective water- and air-tight bond line.

Temperature resistant: Acrylic adhesive resists high temperatures that may be

encountered in outdoor environments.

Tape 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.

Surface Preparation IPA/Water should be used to clean all surfaces to be bonded. Abrasion is sometimes suggested, depending on the adhesion level determined in testing. Testing for adhesion levels is very important. Note: Follow solvent manufacturer’s precautions and directions for use when using cleaning solvents. Related Application Idea Tray to tray attachment.
