  • Patent number: 6818608
    Abstract: A cured resin dissolving composition comprising an alkyl ammonium fluoride dissolved in a wide variety of solvents and co-solvents with a soluble amine and surfactant. The composition is ionized to release fluoride which penetrates and reacts with the cured resin causing bond cleavage, breakdown, and dissolution of polymeric structure. The solvent system may be composed of hydrophilic solvents such as amides, ketones, alcohols, esters, and ethers, as well as hydrophobic families such as alkanes, alkenes, halogenated hydrocarbons, and aromatic hydrocarbons of varying carbon chain length and molecular weight. The rate of reactivity of polymer breakdown is concentration dependent upon ionized fluoride, stimulated by solution polarity and upon the amine triggered release from the organo-fluoirde. This rate is determined to be optimum in hydrophilic solvent systems with an amine. The product may be used in manufacturing to remove unwanted cured resins and their residues.
