Our "Un-hesive" is a really amazing patented marine formula for those of us who have struggled with the impossible task of removing structural type polyurethane adhesives like 3M 5200 Marine Adhesive. It can also de-bond other types of polyurethane adhesives, expanding foams, Gorilla Glue, and marine polysulfide caulks like Sika-flex.
Be sure to take a look at the customer reviews for this product below. This product does exactly what it says, and beats all other products at removing 5200.
- 8 oz. trigger spray bottle
- Water-based formula
- Spray it on any cured polyurethane or polysulfide sealants, and minutes later it can be easily removed.
- Non-flammable and safe on most fiberglass, wood, and metal finishes
- Un-hesive is not a 3M product, but made to remove 3M adhesives and sealants
- Unlike other debonding products, it is water-based, and will not contaminate or compromise sealing or re-bonding when applying new sealants to the original surface.
Additional Unhesive Product Info:
While the cautions on the label on a tube of 5200 will tell you that it makes a permanent bond, which can only be removed mechanically, this amazing marine formula adhesive remover will actually de-bond the 5200 adhesive by breaking the grip between the 5200 and the surface to which it has been applied. It just breaks the bond, but does not break down the adhesive material itself, so it can simply be peeled away without damaging the surface, or requiring hours with a chisel and scraper.
This water-based solution, looks, feels, and smells like a mild kitchen cleaner but delivers impressive results. We know by experience that other so-called de-bonding agents (that come in a tiny 1 oz bottle) just don't perform. They are slimy, smelly, turn the adhesives into a gooey mess, and don't allow the adhesive to be peeled away.
This "Unhesive" will also remove other polyurethane and polysulfide sealants, expanding foam sealants, some glue residues, and even window tint films. We even use it here at the office to easily remove stubborn dry-erase marker scribbles from our whiteboards (we haven't found anything that works better).
So does it really work? It does! Some jobs are tougher than others, but the only ingredient missing in the bottle is the 20 minutes-worth of patience that is needed for the formula to seep between the joint to work its magic. It debonds as it goes, so, it may take some time to seep between the bond. if you spray it on and then go have lunch, the bond will have begun releasing while you are gone. If you've done these chores the old-fashioned way, you will really appreciate having a bottle of this on-board, or in the garage. The formula must stay wet on the bond to do its magic. We recommend finding some shade, or covering with saran wrap if attempting on a hot day in full sun.
How is it different than Anti-Bond 2015™ or De-Bond Marine Formula™?
1). Rather than soften and break down the 5200 and turn it into gooey mess, the Un-hesive formula simply breaks the bond between 5200 and the substrate, be it wood, fiberglass or other material, which normally allows the 5200 to just peel-away.
2). Un-hesive is a mild, fragrant, and water-based formula, rather than a stinky, slick, and oily petroleum-based product.
3). Because it is water-based, and doesn't leave behind a gooey and oily mess, rebonding (i.e. getting other sealants to stick again) is easy. With the competitive products rebonding materials to the same area again is difficult, if not impossible.
4). You get a full 8-ounce environmentally-friendly pump bottle of Un-Hesive for less than their tiny 1.2 ounce or 4 ounce aerosol spray.

Had to remove a 30 gal alum tank attached to sole of a tank coffin. Three full length rows of neoprene attached by 5200 with less than a quarter inch gap between tank and sole. Day 1 lowered trailer all the way sprayed Un Hesive across back edge of tank let gravity do its thing. Day two raised trailer up all the way. Sprayed Un Hesive across front, again let gravity do its thing. Day three slipped a thin pry bar under tank edge and used wood block as fulcrum. Tank popped out in less than a minute. SOLD! Stuff works and no mess.
Worked as advertised. I sprayed on and came back some time later. Bracket pulled easily away from transom. Used it to clean off other areas of 5200. I have already recommended to friends. Glad I found this stuff.
Worked pretty darned good! I was pleased with the results produced how bonded my old fish finder was in my console. Not a messy product to use because it doesn’t actually dissolve the adhesive, it simply breaks the bond. Would have given a five star but the runoff stained my console gelcoat. Had to use rubbing compound to remove the stain.
To be honest, it was better than than any other product I tried but came nowhere near releasing the adhesive on the keel of my boat
Marinebeam edit: This product is designed to degrade and release the bond between 5200 and most surfaces. Structural quantities of 5200 such as keel and window installations will still require manual removal, but this product will help in the cleanup of any remaining 5200.
