New Solvent-Free Glue Once again, SCUBAPRO stands at the forefront of environmental innovation with the development of a new solvent-free glue used in the construction of our 3mm, 5mm and 7mm Everflex steamers. It is universally accepted that water-based adhesives are better for divers, and better for the environment.  Although water-based, this solvent-free glue is tough as nails -- SCUBAPRO engineers made sure of that with rigorous testing spanning more than 400 hours. So you can be confident that you are not only wearing the most comfortable, durable wetsuit available, it\'s also more compatible with a healthy environment.
