Solutions

Blend of high quality foundry bentonite and mineral coal

ECOSIL™ increases the stability of the mold, improves casted product quality by helping to create smooth surfaces, and speeds up mold disintegration after casting. On top of that, it minimizes emission of toxic compounds.

Mode of Action

Easy separation of cast and mold

The lustrous carbon former component of ECOSIL™ creates a very thin shiny carbon layer around the silica grains of the mold sand, facilitating the separation of the cast from it.
