Zusammenfassung:	Silicone sealant composition based on silicone polymer, crosslinker, optionally fillers and a plasticiser, and which hardens by contact with atmospheric moisture, by heating or by addition reaction of its constituents, in which the plasticiser consists wholly or partially of a paraffin oil comprising 36-40 % cyclic paraffin oils and 36-40 % non-cyclic paraffin oils. Preferably the paraffin oil mixture preferably has a chain length of 14-23 C, particularly 16-21 C and a relative proportion of cyclic to non-cyclic paraffin oils of 38:62 %. The paraffin oil mixture preferably has a flash point of ca. 160 degrees C, a density of 850 kg/m and an aniline point of ca. 101 degrees C. The paraffin oils may be used in conjunction with additional plasticisers such as non-reactive polysiloxanes and organic aliphatic compounds.
