<p>Curable organic resin compositions, such as epoxy resins, are provided, based on the use of dialkyl hydroxy arylsulfonium salts in combination with certain organic oxidants such as iodoso-aromatic esters, or the use of certain amines or transition metals in combination with organic peroxides. The curable compositions can provide flexible or rigid organic resin foam when used with a volatile organic solvent as a result of exothermic heat of cure. </p> |
