The chemists at Applied Chemical Laboratories (Sunnyvale, Calif.) have developed what the company says is an environmentally friendly solvent for epoxy and polyester resin cleanup. ACL-23 EpoxSol is designed to remove cured resins from surfaces, with little or no gumming or drying. Derived from technology used to clean microelectronic components, the product reportedly is optimized for fast cleaning, and is virtually odorless, contains no acetone, methyl ethyl ketone (MEK) or methyl isobutyl ketone (MIBK) and can be used in spray or immersion tank applications. Allowable application temperatures are 23°C to 80°C (73.4°F to 176°F) for thick, highly crosslinked epoxy or polyester resin coatings. Formulated to be noncorrosive to metals, the solvent can be used to remove resins from tooling and other surfaces made from aluminum alloys and other metals.
