Organic binders are almost exclusively synthetic resins, which are cured by the addition of a separate hardener or catalyst. Inorganic binders are based on sodium silicates that have been optimised to accommodate the varying casting processes, thus guaranteeing best decomposition.
Gas Setting Resin Systems
CO2 set resin systems.
ECOLOTEC water based resole-CO2 process
The ECOLOTEC process offers a unique combination of environmental, metallurgical and productivity advantages. The resin is mixed with sand and then hardened by gassing with carbon dioxide (CO2) thereby avoiding the problems of smell and emissions.
CO2 and ester setting sodium silicate binder systems.
CARSIL is a range of sodium silicate binders suitable for both moulds and cores.
VELOSET is a range of esters that enhance significantly the strength and reclamation rates of CARSIL bonded sands.
SOLOSIL is a range of low viscosity, high performance, sodium silicate binders with advanced breakdown agents. They are used as a one-shot addition and hardened by CO2.
Additives, Glues, Sealants and Release Agents
In addition to binders and coatings, Foseco offers a range of ancillary products used for the production of moulds and cores. These products include release and parting agents, glues and sealants, and sand additives.
