PRIMARY BINDERS
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.
KEYCOTER binder & concentrate provide foundries with exceptional primary slurry life, increased
wax adhesion and improved wetting characteristics compared to other long-life primary binders. This two-part binder is an excellent choice for zircon or cobalt aluminate slurries as it is stable
over a wide pH range.
PRIMCOTER binder provides foundries with shell coats that dry quickly while reducing, or
eliminating, common metal defects caused by buckling, lifting and cracking. PRIMCOTE binder contains wetting agent, antifoam, and a color indicator to monitor shell dryness. This binder is
premixed and ready to use.
BACKUP BINDERS
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.
MATRIXCOTETM
shell materials provide best-in-class crack resistance, edge coverage, permeability, and ease of shell removal. Slurries can be formulated with or without a fiber
component depending on the foundry’s need to reduce coat application & improve throughput. Let R&R tailor a MATRIXCOTE slurry to meet your foundry’s specific needs.
DELUXCOTER
concentrate is a fiber-based material that, when added to BINDZIL colloidal silica, allows foundries to reduce shell coats without sacrificing shell strength.
CUSTOMCOTER binder is a polymer-based binder. Customcote binder’s excellent wetting properties eliminate 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.
