<p>New compositions for use as protective coatings and/or adhesives are provided. The compositions comprise a hydrocarbon resin (e.g., terpene rosin) and a rubber (e.g., EPDM) dispersed or dissolved in a solvent system. The solvent system is preferably a single-solvent system, and the compositions are preferably free of surfactants, dyes, and chromophores. The compositions can be cured or dried to form layers or films that are chemically and thermally resistant, but that can be readily dissolved and removed at the appropriate stage in the fabrication process.</p> |
