- 34 - ABSTRACT OF THE DISCLOSURE This invention relates to a sprayable hot melt corrosion preventative composition and process for making the composition. The composition is characterized by comprising: (1) between about 10 and about 25 parts by weight of an epoxy resin elastomer adduct mixture, (2) between about 10 and about 25 parts by weight micro- crystalline wax; and (3) between about 50 and about 80 parts by weight of a dispersion of petroleum sulfonate complex in nonvolatile diluent oil. The total weight of (1), (2) and (3) is 100 parts. The composition may additionally comprise up to about 20 parts by weight of optional materials such as pigments, fillers, and/or additional nonvolatile oil.
