Primary shell layers are critical to successful casting results as they provide the surface characteristics that will be visible on the casting. R&R produces colloidal silica based binders that provide excellent casting results and protection against common casting defects.
Backup shell layers create the bulk needed to successfully hold molten metal during casting. R&R produces colloidal silica based binders specifically designed to build bulk quickly through advanced drying or coat building characteristics.
Ready-to-use, pre-mixed, chemically suspended ceramic shell slurries developed to eliminate costs associated with continuous mixing and to simplify the initial mixing process as the pre-mixed, chemically suspended ceramic shell slurry eliminates the need to weigh and mix binder and refractory components.
