Genuine SONEX polyurethane adhesive for sound-absorbing materials. Used with a caulking gun, it can attach melamine foam sound-absorbing materials to wall surfaces.
This adhesive can also be used for sound-absorbing materials. Its main component is modified silicone resin, which hardens by reacting with moisture in the air. After hardening, it has rubber-like elasticity, which cushions the movement of the material.
