ABSTRACT:
Storage stable mastic adhesive is produced by blending a neoprene latex having a gel content of at least 60% and a neoprene latex in which the polymer is at least almost completely soluble in toluene and mixing the blend with an organic water-immiscible solvent for neoprene until a water-in-oil type dispersion is obtained. The viscosity and/or storage stability of the mastic can be further increased by the addition of water to the mastic.
