Neoprene made from an emulsion by the so-called "dipping process" seems to be a particularly difficult material to glue, presumably because of the surfactant residues which interfere with the (toluene based neoprene) glue. In line with upcoming legislation, I need to replace the toluene solvent with a more benign one. All water based neoprene adhesives I have tried fail to give the required bond strength. Only toluene seems to swell the neoprene enough to overcome this effect and allow a good contact with the glue. Any other suggestion ?
