Anwendungen & Verwendung
Verwenden
N,N'-Ethylenebis(stearamide) is a bis-amide polymer additive that lowers the temperature at which the asphalt softens. It is used as processing aid for resins and polymers and as defoaming agent. It is traditionally used as lubricant and binder for cold compaction of powdered metal parts.
