CONSTRUCTION INDUSTRY
- Concrete & Cement grouts additive, high performance concrete: Bridge, well, building & road construction through denser water-free structures, self-compacting concretes.
- As stabilizer and sedimentation reducer.
- Drying & Drainage: Brickwork/Stonewall drying by pore closure - Drainage barriers.
- Ground Consolidation: Creation of soft gel-structure for the consolidation of sandy subsoils by closing of the finest soil cracks & capillaries.
- Shotcrete additive: Control of the flow behavior of concrete sludge.
- Tunnel construction: Consolidating of loose rock layers and closure of finest cracks & capillaries.
REFRACTORY & CERAMIC INDUSTRY
- Ceramic insulation: Binder in insulation applications (heat or electricity) in power line and transformer construction (High-voltage isolators); High-temparatursensor coating, wire-armored heating elements, Insulating plates.
- Stoneware & Porcelain materials: Dispersants, fluidizing agents & firing aid in the production of porcelain and stoneware.
- Vacuum forming products: Manufacture of vacuum molded segments and boards with ceramic fibers.
FOUNDRY- & INVESTMENT CASTING INDUSTRY
- Binder:Combined with additives as binders in prefabricated molded bodies filled with fillers.
- Building of sand molds: Binder for foundry sand molds for better molding and reinforcement
- Dipping masses: For the primary cover &, if necessary, also for the secondary coverings of ceramic molds & cores.
- Precision Investment Casting: Wax casting or shaw process, application for highly complex castings in automotive, engine & aircraft construction as well as medical fields such as implants & instruments.
