Zusammenfassung:	Release agent used in moulding plastics, especially polyurethanes, is based on organosilicon compounds and low-molecular siloxanes. It comprises 0.1-5.0 wt.% polysiloxane (I) containing gamma -aminopropyl groups, 4.0-60.0 wt.% polysiloxane of formula (II) and 35.0-95.9 wt.% solvent(s) based on halogen-free hydrocarbons with a flash point of more than 55[deg] C (where, a = 7-13). (II) contains less than 5 wt.% compounds in which a is less than 7 and not more than 5 wt.% compounds in which a > 13.
