| 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. |
| PRIMCOTE BINDER - PRIMCOTE 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. Click here for PDF Instruction sheet. |

| CERAMIC SHELL INVESTMENT REFRACTORIES |
| RANCO-SILTM fused silica is electrically fused, high purity silica. Fused silica has a low thermal
conductivity and excellent thermal shock resistance. These properties, along with its low density,
make it an excellent refractory for use in a ceramic shell mold. RANCO-SIL fused silica is available
in flour and granular forms.
RANCO-SIL fused silica can be used throughout the ceramic shell. When used in the primary slurry it is typically blended with zircon depending on the alloy. Shells constructed with fused silica hold their dimensions better and are not prone to hot deformation or bulging. Shell knockout is also easier with fused silica refractories. |

| Alumina Silica is produced from calcined mullite that is precisely sized as either flour or grain. Mulcoa alumino silicates are available in three alumina contents: 47%, 60% and 70%. In the investment casting industry, 47% is the standard that provides consistent product economically. These products are low in iron, alkaline and alkaline earth elements. Alumino silicates are typically used in the backup slurry and as backup stucco. | ||||

| ZIRCON SAND 325 - Zircon is a naturally occurring refractory mineral. It is chemically inert and is stable to very high temperatures. Zircon has a very high thermal conductivity and acts as a chill to eliminate metal mold reactions and burn-in resulting in a smooth cast surface. Zircon is available in both flour and granular form.
Zircon is almost exclusively used in the primary slurry and as a primary stucco. Because of its high density, it provides excellent flow characteristics in a primary slurry. The round grains produce smooth casting surfaces, reducing rough casting defects. |
