The present invention relates to a mixture of polyalkylsiloxanes obtainable through a hydrosilylation reaction wherein a mixture of monounsaturated olefins is reacted with an amount of one or more polyalkylhydrosiloxanes in the presence of a hydrosilylation catalyst. Furthermore, the invention concerns polyalkylsiloxane comprising alkyl side chains consisting of linear or branched alkyl groups with 40 to 60 carbon atoms, with 16 to 30 carbon atoms, and 6 to 15 carbon atoms. In addition, the present invention relates to water-based compositions suitable for use in metal casting processes as a mold release agent comprising a mixture of polyalkylsiloxanes, a non-ionic surfactant having a HLB value of at least 8, and less than 20 wt.-% of waxes. In addition, the present invention relates to the use of the polyalkylsiloxanes and mixtures of polyalkylsiloxanes.

摘要:
In order to obtain a cold rolled steel sheet having excellent press formability, a cold rolled steel sheet has, on a surface thereof, an organic-inorganic composite film containing: an organic resin; and a crystalline layered material. The organic-inorganic composite film has an average film thickness of 0.10 to 2.0 μm and contains 0.5 part or more by weight of the crystalline layered material as a solid with respect to 100 parts by weight of a solid of the organic resin. The crystalline layered material preferably is, for example, a layered double hydroxide represented by [M2+1-xM3+x(OH)2][An−]x/n.zH2O, where: M2+ is one or more of Mg2+, Ca2+, Fe2+, Ni2+, and Zn2+; M3+ is one or more of Al3+, Fe3+, and Cr3+; and An− is one or more of OH−, CO32−, Cl−, and (SO4)2−.
