| BINDZIL®
2040 is a larger particle (20nm) colloidal silica that gives better
refractory fiber composites. Extensive pilot plant studies show it gives
stronger vacuum formed boards and shapes with better high temperature
properties than the smaller particle silica sols. BINDZIL®
2040 is a colloidal dispersion in water of 20 nanometer amorphous
silica spheres at an economical 40% concentration. It is also available at
50% concentration as BINDZIL® 2050. |

BINDZIL® 2040 offers these advantages
|
|
|
| Stronger
Bonding and Hardness - |
Larger particle
size yields higher green strengths (i.e., modulus of rupture) and harder
refractory fiber shapes. |
| Better
High Temperature Properties - |
Larger particle
size and lower sodium content gives lower shrinkage at temperatures up to
2300oF. |
| Saves
Money - |
Balanced silica to
starch floccing ratio is more economical giving high strength with less
colloidal silica in formulation. |
| Rigidizes
Better - |
Larger particles
soak in further and giver stronger, harder rigidized products; lower
sodium results in less shrinkage at end-use temperatures. |
| Flocs
with Cationic Starch - |
Negative surface
charge flocs cationic starch refractory fibers together to form a three
dimensional floc for good product strength. |
