The release agent compositions in an appropriate range of viscosity could decrease liq- uid deposit, minimizing the impact on the strength of specimen edges . But the experiment discovered that a release agent composition containing polysiloxane ( s ) having a viscosity higher than 60,000 mPa.s was likely to lead to contamination of the specimens.

  • Examples 3 and 6 showed that the release agent compositions containing polysiloxane (s) of a relatively low (68 mPa.s) or high (60,000 mPa.s) viscosity exhibited excellent demolding properties .
  • Examples 1 and 3 to 6 showed that the release agent compositions containing polydimethylsiloxane and hydroxy-terminated polydimethylsiloxane scored relatively high total points with their good demolding properties, wherein the release agent com- position containing polydimethylsiloxane of Example 5 scored the highest total points with its best demolding properties.
  • Examples 1 and 5 showed that the release agent compositions with a viscosity value respectively at the two endpoints (1,000 mPa.s and 7 mPa.s) scored relatively high total points, indicating that the two release agent compositions could still pro- vide excellent demolding properties.
