Abstract
The invention provides a silicone-based working fluid composition having improved heat resistance which comprises (A) 100 parts by weight of a base component composed of a first dimethylpolysiloxane terminated at both molecular chain ends each with a trimethylsiloxy group and a second dimethylpolysiloxane terminated at both molecular chain ends each with a silicon-bonded hydroxy group in such a proportion that the trimethylsiloxy/hydroxy molar ratio is from 95/5 to 10/90 and (B) from 0.01 to 5 parts by weight of an additive component which is a diorganopolysiloxane having imino-containing phenoxy groups, e.g. 4-anilinophenoxy group, 4-(4-anilino)anilinophenoxy group, 4-(.alpha.-naphthylamino)phenoxy group and 4-(.beta.-naphthylamino)phenoxy group, as the pendant groups on the polysiloxane.
