| Wesil PRX | |
| Binder system to reduce phenolics | |
|
WESIL PRX Binder is a blend
of natural starches and our proprietary aluminosilicate binder designed
to reduce phenolic resins in low- fiber hot top boards and other insulating
fixtures used in metal production, smelting, and casting. WESIL PRX is not quite as effective as some phenolics and may require more for equivalent hardness; we suggest you try it first at 5% by weight and adjust from there for desired strength and hardness. |

|
| Replaces Noxious Phenolics — |
No "Phenol" fumes during use, and greatly reduced waste water
disposal problems. |
| Lower Drying Temperatures — |
Contains a heat set resin that cures at 200°F so good strength is
obtained at a drying temperature of 250°F, eliminating the high baking
temperature required with phenolics. |
| Moisture Tolerant Parts — | Formed parts are
more able to maintain hardness and strength if exposed to humidity. |
| No Cristobalite — | Completely cristobalite
free at use temperature eliminating a common source of thermal shrinkage
problems and health related concerns. |
