REFRACTORY & CERAMIC INDUSTRY
- Refractory Materials: Linings for high-temperature furnaces, manufacture of refractory fiber bonding (RFB).
- 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.
ELECTRICITY STORAGE & ELECTROMOBILITY
- Gel & AGM Accumulators: Generation of solid electrolytes for leak-proof, acid-based systems e.g. in valve-regulated, lead-acid batteries (VRLA) and for the reducing of the acid stratification in absorbed glass mat batteries systems (AGM).
- FIRE PROTECTION APPLICATIONS
Fire protection glass:For the generation of a water-storing, transparent gel embedded between glass panels.
PAINTS, VARNISHES & PIGMENTS
- Adhesion and scratch resistance: As an additive to paint formulations for increasing the scratch and abrasion resistance and the breaking strength for various substrates such paper, metal, wood.
- Filler & Matting Agent: As a functional additive for influencing the color reflection.
- Heat- and corrosion protection: Heat-resistant paint systems and areas exposed to weather conditions such as moisture and salty atmospheres.
- Paints based on organic solvents: Binder in organic paint systems.
- Silicate paints for facades & interior areas: Water- & dirt-repellent color formulations, silicate paints & siliceous products.
- Waterborne Varnishes & Paints: Improve the penetration and wetting of e.g. wood and subsequent increase in scratch resistance.
FOUNDRY- & INVESTMENT CASTING INDUSTRY
- Embedding compounds: Binder & filling material, mixing liquid for embedding compositions.
- 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.
