Beschreibung
Zusammenfassung:	One-part room-temperature curable compositions (RTV-1 compositions) based on organosilicon compounds have improved storage stability and excellent physical properties, and contain (A) at least one organosilicon compound containing condensable groups, (B) at least one curing agent comprising a combination of n-propyltriacetoxysilane and methyltriacetoxysilane, and (C) at least one curing catalyst comprising an organotin compound. The curing agent is a combination of n-propyltriacetoxysilane and methyltriacetoxysilane reduces the tendency of the composition to crystallize without impairing the chemical and physical properties of the composition.
