Solutions
Natural clay mineral-based foundry bentonite GEKO™ foundry bentonite is made out of highest quality bentoniteIt allows for highest mold stability during the foundry process, shorter mixing times and quick disintegration at knockout.
Mode of Action
Good fluidity and high elasticity of sand moldThe chemically activated foundry bentonite GEKO™ deposits water molecules between the clay mineral layers, which have been expanded by the activation. It swells rapidly and thus has a good binding capacity to hold the casting mold’s grains of sand.
