As an innovative foundry supplier, Hüttenes-Albertus soon started to develop cold box binder systems with improved properties. In 1999, the first generation of cold box systems with solvents containing silicate was used in foundries. Compared to the aliphatic and aromatic solvents used until then in the cold box process, the use of tetraethyl orthosilicate was the first step towards a cold box system of an inorganic nature.

Currently, the (TES) system coexists with traditional systems based on aliphatic solvents (Biodiesel or RME) and aromatic solvents. These two systems are very popular within the foundries.
