Care needs to be taken as Acetoxy silicones release acetic acid when curing which can cause corrosion Since the acetic acid is released during curing, it can attack the underlying substrate material. This can cause corrosion of certain
metals and prevent the proper adhesion of the silicone. However, on other materials, the acid can etch the surface slightly and increase the adhesion. Aluminium is one such material. Copper and zinc, carbon steel however, are
corroded by the acid. Dissimilar metals can form electrolytic couples and corrode severely underneath a covering
