Customcote binder is a polymer-based binder that produces strong ceramic shells with many potential benefits over standard colloidal silica and ethyl silicate shells.
Customcote binder can be used for primary and backup shell coats. It can also be used with a variety of refractories depending on the individual foundry’s process and casting requirements.
Customcote binder’s excellent wetting property eliminates the need for prewets. The binder’s lower slurry viscosity allows for better coverage in slots and shorter drain times than standard colloidal silica slurries.
The thinner, yet stronger, shell results in reduced shell material consumption and less shell material for disposal. Shell weights versus standard colloidal silica shells can be reduced significantly depending on the number of shell coats the foundry currently uses.
