Product Description

VHB tapes are suitable for bonding sealed wood, many plastics, composites and metal. Meets UL746C. After application, the bond strength will increase as the adhesive flows onto the surface. At room temperature, approximately 50% of the ultimate strength will be achieved after 20 minutes, 90% after 24 hours and 100% after 72 hours. In some cases, bond strength can be increased and ultimate bond strength can be achieved more quickly by exposure of the bond to elevated temperatures (e.g. 150°F [66°C] for 1 hour).

From the Manufacturer

3M&™ VHB™ Tape 4941 is a conformable, double-sided, pressure-sensitive, closed-cell acrylic foam tape with a paper liner, designed to permanently adhere one material to another while spreading the stress load across the entire length of the joint. Once materials are joined, the tape creates a strong bond that resists moisture, plasticizers and temperature extremes.

The Better Way to Bond
3M™ VHB™ Tape fits into grooves, around corners and through curves while offering a durable bond. The result is an extraordinarily strong tape that holds fast to a wide range of materials. Applications include bonding and sealing lenses over LED panels, bonding pre-painted metals, bonding and sealing plastic windows to pre-painted panels. 3M™ VHB™ Tape can enhance the appearance of finished goods by eliminating rivets and screws while providing immediate handling strength. In most cases, fastening with 3M™ VHB™ tape is a quicker process than drilling, fastening, or using liquid adhesive. 3M™ VHB™ tape can be used indoors or outdoors in a variety of applications, including window and door assembly, sign assembly, electronics, maintenance and dozens of other industrial applications.

 

Documented Reliability
3M™ VHB™ Tape 4941 provides cushioning, damping, and impact resistance. The tape is also plasticizer resistant and carries a UL listing, 746C. Qualification for this listing requires high-strength retention after extended exposure to high temperatures, humidity, cold, and cyclic conditions. The listing below details 3M™ VHB™ Tape 4941 with the UL 746C listing, and substrate combinations, as well as the maximum listed temperature for each combination.

 

Can Tape Really Replace Mechanical Fasteners?
Yes! 3M™ VHB™ Tape is a proven alternative to screws, rivets, welds and other forms of mechanical fasteners. Skyscrapers, cell phones, electronic highway signs, refrigerators, marine electronics, architectural windows, recreational vehicles and trailers all rely on 3M™ VHB™ tape for one or more steps in the assembly, mounting, fastening, and sealing process. When joining seams, 3M™ VHB™ tape helps create clean, smooth, water-resistant results without rows of rivet, fastener heads, or weld seams, which also allows for large-area graphic application with no need for additional smoothing to accommodate fastener head protrusions.
