This product is a contact adhesive from Soudal, primarily composed of neoprene. It is thixotropic, meaning that it liquefies under stress. The result is as the glue is squeezed out of the tube it will become runny for easy application, but will become solid again once it has been applied. Soudal contact gel should be applied with a trowel or a brush.
Soudal Neoprene Contact Gel is fantastic for sticking things like rubber, plastic, and cork. In addition, it even glues to leather and felt well. These can be stuck to each other or to other materials.
No primer is required. Soudal Neoprene Contact Gel is moisture resistant and dries quickly.
