Abstract
Waxes, particularly paraffin and microcrystalline waxes, can act as corrosion inhibitors when added at low levels to compositions based on thermosettable resins such as epoxy resins. When such wax-modified thermosettable compositions are used to coat a metallic surface, enhanced protection of the metallic surface against corrosion due to environmental exposure such as salt spray is obtained. The thermosettable compositions are particularly useful in expandable or foamable form for imparting structural reinforcement to hollow metal parts such as automotive components.
