MicroSealant

What is MicroSealant?

  • MicroSealants are a family of sealants that contain no double bonds between carbon atoms, but are comprised of a single bond between carbon atoms which result in a molecular structure that is extremely stable and is resistant to oxygen, ozone, and heat.
  • MicroSealant tapes are formulated from synthetic polymers and contain a proprietary built-in primer that facilitates instant bonding to most known materials used in: transportation, roofing and the traditional building envelope.
  • MicroSealants have an extremely wide temperature tolerance. When properly installed, MicroSealants will bond to almost any selected substrate, resulting in a waterproof seal. MicroSealants are self-healing. MicroSealants are extremely robust to a wide range of surface condition reducing steps during installation.
  • MicroSealant - contains no solvents due to its completely VOC-free proprietary primer and will not compromise air quality within the building envelope.

HB Fuller

  • EternaBond bonds to virtually any surface except silicone. This includes all roofing materials, brick, wood, metal, stucco, rubber, vinyl, canvas, etc. So EternaBond is the perfect repair product for buildings, RV's, tents, sheds, canoes, tarps, etc.
  • Also, EternaBond has an expected life (depending on where you live) of 18-35 years exposed to the weather. EternaBond has a 5-year shelf life so if you don't use it all at once it will be ready when you need it.

    Butyl rubber like  Dicor BT-1834-1 1/8" x 3/4" x 30' Butyl Seal Tape  is probably better than this product for sealing-down roof-mounted objects on an RV, since it is so insanely flexible and sticky, but this tape is a lot easier to work with in applications that are awkward to reach or otherwise make installation difficult.

    I have used this tape for miscellaneous screw-hole sealing on the inside of the front wall of our travel trailer to install Murphy fasteners for a "bra" to cover the windshield. A layer of this tape over the screws protruding through the wall, then a piece of 
    EternaBond RSW-4-50 RoofSeal Sealant Tape, White - 4" x 50'  on top of that to finish covering the length of screw and prevent the fiberglass insulation I added from sticking to the sealant, and "job done" (and sealed for a lifetime).

    This product is also great for adhering

All I had to do was clean the frame with mineral spirits, apply the tape to the LED strips, remove the backing tape, and rub the strip down on the frame - and trust me, it is NEVER going to come off!! Beats the heck out of trying to drill the frame to install the cheap screws and clips that come with the channel strips, which would never "last" in this type of application.

    I used this to repair a tonneau cover on my truck. The tonneau cover is one that rolls up with aluminum slats linked together and held in place by the vinyl fabric glued to the aluminum slats. Unfortunately, the glue dried over time and separated from the vinyl fabric. Couldn't roll the tonneau cover up without it falling apart. I put several strips of this Eternabond double side tape across the slat from front to back. It's been three months now and the tonneau cover works like it is supposed to. Very please with the product so far. Highly recommend.

    My first experience with this product was with a half used roll that someone gave me. I tried to use it as a gasket behind some marker lights. I found it to be incredibly difficult to work with. Cutting it with a razor blade made a huge mess. At that point, I was at a loss for locations on my trailer that the doublestick tape could be used (easily).

    My second experience was with a roll of my own that was brand new. I had stored it in the refrigerator for a couple days. That made a critical difference. Cutting it was much easier. It would be easier to work with if it came off the roll with backing on both sides, but it comes off with backing on only one side.

    I used it on my RV between the fiberglass and a diamond plate aluminum skirt. The manufacturer had used staples to hold the original diamond plate in place before attaching molding with butyl tape under it. The doublestick putty tape held the entire length of diamond plate on the trailer all by itself!

    I still think a double sided taped has limited usefulness on an RV trailer. There are far more uses for the regular, single sided Eternabond.

    I recently ordered this product because I am remodeling my 2003 forest river Salem and needed butyl tape for the roof membrane, door, and side door. I have used this tape on the roof so far.

    What I like about this tape is how squishy it is. It has a similar consistency to bubble gum. The tape has a clear plastic backing that you peel off to make it easy to install. occasionally the tape sticks so well it will actually stick to itself, so once you start unrolling, DON'T STOP. Then it works well.

    Almost any product by eternabond is fantastic.

    I used this to adhere a 1/2 in. resin 26"X26" cover to the top of my shuttle bus after removing the escape hatch. Of course, I framed out the inside with plywood to cover the opening. Then applied 3 strips around the perimeter of the resin panel placed it after cleaning my roof surface. I have driven it since over 1000 miles and I believe it is more solid now than when I finished. I live in Tn. and started in the summer. Now in Jan. the temps. are -10 with windchills and no difference in adhesion. Pricey product, but where can you get such results from over the counter look alikes that you can't count on. I guess permanence and peace of mind makes it a sure buy.

    Works like a charm with no mess, just peal and stick to a clean surface and roll out any air pockets. That is the key to an everlasting seal, making sure the surface is clean and no air gets traped between the putty and the surface.
