Specific features of CENUSIL® M 810 A/B

  • Addition Curing
  • Fast curing at room temperature
  • Flowable
  • Low viscosity
  • No chemical shrinkage
  • Two-component

Due to the outstanding elongation and low demolding forces as well as the superior mechanical properties, CENUSIL® M 810 A/B is especially suitable for preparing glove molds, i.e. one part skin molds.

The benefits are easy and quick mold making as well as straightforward demolding and seamless copies. Hence no further rework of the reproduction is required and process time is being extensively reduced.

As a low-hardness addition-curing RTV-2 silicone rubber that cures without undergoing dimensional shrinkage CENUSIL® M 810 A/B is especially suitable for casting all common reproduction materials, particularly if absolutely accurate copies of models with pronounced undercuts are required.

Mix components A and B in a ratio of 1 : 1.

Important note:
The platinum catalyst is contained in component A.

Important: A and B components may only be used together if they have the same batch number.
