3M VHB Bonding Tape

[geoffrey chew]

Just to give an endorsement of this heavy duty double sided acrylic foam tape for attaching solar panel support frames to your TM roof. I used this tape to fasten 2 x 80W panel support frames on the rear roof of my TM and the adhesive strength was very impressive, absolutely no drilling was required to secure the frame. But be precise when using because you can not slide it, initial touch down is final final. Many hardware stores don't seem to have heard of VHB but it can be purchased online from 3M.

I appreciate your post as I will be looking for a way to attach a panel to the roof of our Elk in a couple weeks. How many trips have you been on since installation? And as far as you know is there and detereation possible due to UV or the elements?

I too like this idea. 3M has an excellent rep in adhesives and sealants. I always keep a tube of 4200 around for roof work if needed (not recently, thankfully).

And we've used their interior hooks a lot in our trailer. The tape on the back of them is probably very similar, and they work well.

At the bottom of this web page, there's a pdf about long-term durability:

I mounted my two 80 watt panels with 3M VHB tape over two years ago and they're still on solid. We've probably travelled over 12,000 miles in that time.

Another member who has since bought a different trailer used the same method and was able to get the mounts off using a putty knife when he moved the panels to his new trailer.

He indicated at the time it was easier than he thought it would be, but he still trusted the tape enough to use on his new trailer.

Good feedback...thanks!

OK, I'm looking on line for 3M VHB tape and there seems to be quite a few to choose from as far as thickness and application. Can anyone point me to the exact one that I need by giving a part number or link?

Thanks!
