|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
