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.
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.

The key with this, as with any other adhesive-based product, is proper substrate preparation. It needs to not only be clean, but free of any oily residues. Don't wipe it with regular household cleaners, as they tend to leave behind residue. Your final pass should be with 99% or higher isopropyl alcohol. The standard household rubbing alcohol is usually 70-90% alcohol, and the rest is mostly water. This works too, but 99% is better.
Also, ideal application temperature is 68-104F (20-40F). Below these temperatures, the adhesive doesn't like to bond well to the substrate. Adding a little pressure and heat will always help the bond.
If you are bonding to a very slick surface (low surface energy) such as a powder coated steel or polyethylene, you may need a different VHB product. We have used 4952 in these applications with good success, which is specifically designed for LSE substrates. You can find it for a decent price at McMaster.com
I wiped down the window frame and cut the tape to fit the mounting brackets. I applied the tape to the brackets and heated it with a hair dryer. Then, I applied the brackets to the inside of the frame. The next day, I put up the first "test" blind and it held. We came back the next day and it was still up so I went ahead with the rest of them. An hour later, all of the blinds were installed. It has been almost two months and we haven't had a single incident. They are all still holding well with regular use.
I honestly think that if I had a choice between mounting the blinds with screws and mounting them with this VHB tape, I would do the tape again. It was that easy! I can't wait to find more applications for this amazing tape.
This is a small roll of tape, 5 yards doesn't go all that far. Excellent product.
