Silanes and silicones for engineered stone

Silanes and silicones have clear advantages in the production of engineered stone.
Silanes form bridges between organic and inorganic components, which helps give engineered stones their outstanding properties.
The superior UV and heat resistance of silicone resins makes engineered stones suitable for use in new applications.

GENIOSIL® silanes create a chemical bond between the organic and inorganic components of engineered stone, thus improving its mechanical properties.

Engineered stone is a composite product based on minerals and unsaturated polyester resins. Silanes from WACKER's GENIOSIL® range produce a chemical bond between the organic resin and the inorganic mineral, while also greatly increasing mechanical strength. Just 1% GENIOSIL® relative to the binder is enough to transfer the strength of the hard, inorganic system to the soft, organic system.

Advantages

  • Chemical bond between the resin and fillers
  • Improved mechanical properties
  • Greater flexural strength

Application:

  • Production of engineered stone

UV-resistant engineered stone for exterior applications? Silicone resin is what makes it possible. Replacing unsaturated polyester resins with a high-quality silicone resin binder makes engineered stone usable in exterior applications. Yellowing or fading as a result of direct sunlight is no longer an issue.

Advantages:

  • Outstanding resistance to UV and heat relative to organic binders
  • Drop-in solution for existing production plants
  • Contains no styrene
  • No need for an additional adhesion promoter
  • Mechanically robust, resists scratches and stains, offers design freedom

Applications:

  • Production of UV-resistant engineered stone for exterior applications (such as outdoor kitchens and rooftop patios)
  • Production of heat-resistant engineered stone (for barbecues, etc.)
  • Siding, outdoor flooring, etc.

The UV resistance of products based on SILRES® BS 7070 is outstanding.
