Gluing Neoprene
Polychloroprene rubber used for gaskets, wetsuits, pads and vibration mounts.
Also called CR rubber, polychloroprene, wetsuit material.
How Neoprene behaves when you bond it
Large flexible areas are commonly matched to contact adhesive because it spreads thinly and remains compliant. Selected cyanoacrylates suit small, close-fitting repairs but can create a stiff edge. Permabond directly reports neoprene bonding with its TA46xx structural acrylic range, including substrate failure in a stated neoprene-to-polypropylene test.
Neoprene is the common name for polychloroprene rubber. It is supplied as solid sheet, closed-cell foam and fabric-faced foam, and these forms do not present the same bonding surface. Solid rubber is non-porous and flexible; foam can fail within the cells, while a fabric facing behaves more like a textile.

Surface preparation
Identify whether the bond is to solid rubber, cut foam or fabric facing. Remove talc, dust, oil and release agent. For a structural adhesive process, use only light abrasion that does not tear the rubber, wipe away debris with isopropyl alcohol if the compound tolerates it, and let it dry. Keep solvent away from foam until a hidden-area compatibility test shows that it does not swell or collapse the cells.
Which adhesives work on Neoprene
Excellent
Contact adhesive
The flexible, thin bond line and full-area application suit sheet and foam laminations. Solvent can damage some foams or facings, so the product must explicitly cover the neoprene form and should be tested on an offcut.
Excellent
Structural acrylic
Permabond reports neoprene substrate failure in a TA4611 neoprene-to-polypropylene test and lists neoprene within the TA46xx rubber scope. These products also provide more gap and area capability than cyanoacrylate.
Conditional
Cyanoacrylate
Cyanoacrylate can suit a small close-fitting repair, but a standard grade produces a stiff edge and is a poor match for broad flexible foam. Choose a rubber-toughened grade and keep the bond area small.
