The KEYCOTE system is a two-part primary binder system. KEYCOTE concentrate and KEYCOTE binder are blended together at a 1:4 ratio when building a slurry.
The KEYCOTE system is stable over a wide pH
range. A newly built slurry has a virtually neutral pH of approximately 7.5. Over time, acidic slurry components like zircon and cobalt aluminate will cause the pH to drop. However, the KEYCOTE
slurry’s integrity is not compromised with this pH shift. The KEYCOTE system is designed to perform despite pH change. By design, no pH testing is necessary with a KEYCOTE slurry. Slurry
maintenance typically requires only periodic water addition to compensate for evaporation.
Because the first coats of any shell are integral to a successful casting, the adhesion properties of the KEYCOTE system are an improvement over other long-life binders. In fact, tested under adverse conditions,
the KEYCOTE system adhered to wax patterns that were still coated with silicone mold release agent.
