The result of beautifully shaped, stable concrete and artificial stone castings is based on alkali resistance, efficient reproduction of even and uneven surfaces and long-term durability of the end product. Addition-curing ELASTOSIL® M products are industry benchmarks in this field.

Advantages:

  • Exceptional dimensional accuracy / shrink-free
  • No need for release agents
  • Large number of copies for concrete, artificial stone or gypsum

Applications:

  • Facade elements, decorative elements
  • Facing bricks for indoor applications
  • Matrix / Stamp for imprinting, stamping and texturing concrete
  • Tiles
  • Bathroom fixtures such as shower basins, sinks
