ABSTRACT:
A quasi-azeotropic stripper composition for the removal of paint or other organic coatings from metallic surfaces and including a formulation containing 1-10% by weight of an alcoholate activator consisting of sodium methoxide, 10-14 20% by weight of a coupling agent and co-solvent consisting of methanol, and 70-89% by weight of an aprotic polar solvent consisting essentially of N-methyl-2-pyrrolidone. The formulation is desirable for use in the work place since it is non-halogenated, is relatively non-volatile under normal ambient conditions, and also possesses a reasonably useful and high flash point.
