As was noted earlier, virtually any elastomeric material can be, and probably is currently, made into an adhesive or sealant. All elastomers are soluble in one or more organic solvents which allows the production of a solvent-based adhesive. Many elastomers are polymerized in an emulsion process, which yields a latex. And a number of elastomers have a low enough glass transition temperature to permit use as a hot-melt polymer, or as one ingredient in a hot melt formulation. Summary statements describing a few of these other polymers follow, but without the detail provided for the primary elastomers.
