  • the performance of the curable, multicomponent mass is significantly reduced.
  • the performance of the curable, multicomponent mass can in such an arrangement by changing the mixing ratio z. B. from 3: 1 to 5: 1 can not be increased, as this would reduce the available total concentration of the peroxide further.
  • peroxide contents in a chamber of the second film bag of the film package can be realized, which can be greater than 1%, the peroxide content relative to the components in the second film bag with the two film chambers at mixing ratios of 1: 1 to 10: 1 is less than 1%.

  • the ratio of the second part of the first component to the second component is in the range of 0.5: 1 to 7: 1, preferably in the range of 2: 1 to 5: 1, and the ratio of the entire first component to the second component in the range from 1: 1 to 10: 1, preferably in the range of 2: 1 to 7: 1.
  • the abovementioned ratios of the components or the parts of the components to one another ensure the provision of different high-performance curable compositions which require no special labeling.
  • the film bag are fixed inextricably with their corresponding ends on the head part and thus captively connected thereto.
  • the entire film pack is easy in the recording of Auspressilless insert and removable from this.
  • the film bags are glued to the headboard.
