Ethylene bis stearamide is by far the most important amide wax.
It is a reaction product of stearic acid and ethylenediamine, made under elevated temperature under nitrogen atmosphere—a standard process.
Stearamide, or octadecamide, can be used as a sensitizer and slip additive in thermal paper coatings as well as a slip and antiblock additive in polyolefin films.
