Abstract:
The present invention relates to a mixture of polyalkylsiloxanes that cure at temperatures of about 170° C. while being unreactive under ambient conditions during storage or transport and which are obtained through a hydrosilylation reaction wherein a mixture of ethylenically unsaturated olefins consisting of 1-100% of one or more polyene(s), and 0-99 mol % of monounsaturated olefins with 6 to 15 carbon atoms is reacted with an amount of one or more polyalkylhydrosiloxanes in the presence of a hydrosilylation catalyst. Furthermore, 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 of the invention and a non-ionic surfactant. In addition, the present invention relates to the use of the polyalkylsiloxanes and mixtures of polyalkylsiloxanes as defined herein.
