Megasol S50
Silica binder for refractory fibers
MegasolS50 is the optimal colloidal silica for bonding and rigidizing of refractory fiber shapes and boards. MegasolS50s unique physical properties result in higher packing densities and stronger bonds. With approximately one third the surface area of commonly used binders, MegasolS50 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 - 2300oF 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.
