| Megasol® S50 | |
| Silica binder for refractory fibers | |
| Megasol®S50 is the optimal colloidal silica for bonding and rigidizing of refractory fiber shapes and boards. Megasol®S50’s unique physical properties result in higher packing densities and stronger bonds. With approximately one third the surface area of commonly used binders, Megasol®S50 requires less cationic starch to floc and yields higher silica content boards and shapes with better high temperature performance characteristics. | |
|
Megasol® S50 offers these advantages |
|
| Greater Product Strength — | Double the dried
and fired strengths than other commonly used colloidal silica binders. |
| Flexibility in Formulation — | Creates stronger
boards than other sols at silica to starch rations of 1:1 through 4:1. |
| Lower or No Smoke Products — | You can use as
little as 2% starch and still get excellent floccing and product strength
resulting in little or no smoking at elevated use temperatures. |
| Less Shrinkage at High Temperatures — | Larger particles
and low sodium content creates less sintering and less shrinkage at 2100
- 2300°F use temperatures. |
| Better Rigidizing — | Larger silica particles
soak in farther and faster for greater hardness throughout. |
| Saves Money — | Higher green and
fired strength means you can formulate using less starch and silica, lowering
material costs. |
