Abstract
An activator composition having increased effectiveness and life when used in an aqueous alkaline stripper solution at elevated temperatures to remove siccative coatings from substrates containing two essential components A and B. Component A consists essentially of at least one of an ethoxylated tetrahydrofurfuryl, a mixture of an ethoxylated tetrahydrofurfuryl and an ethoxylated furfuryl, N-methyl-2-pyrrolidone and N-(2-hydroxyethyl)-2-pyrrolidine. Component B consists essentially of at least one of N-phenyl-diethanolamine, furfurylamine, tetrahydrofurfurylamine, octadecylamine, butoxypropanolamine and N-amino-morpholine.
