Solutions
Natural clay mineral-based foundry bentonite GEKO™ foundry bentonite is made out of highest quality bentonite

It 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 mold

The 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.

EcoTain®
Sustainable green sand additives

Having the highest productivity and being a good neighbour has never been this easy for foundries. Clariant’s two-tiered solution for a drastic reduction of BTEX emissions from green sand while maintaining high throughput, clean casting surfaces and low scrap rates.
