| Very large particle
size colloidal silica |
| BINDZIL®
9950 is a very large particle size (100nm), low-sodium colloidal
silica that is used in ceramic fiber insulation, frictionizing
applications, and abrasives. BINDZIL® 9950
is a colloidal dispersion in water of amorphous silica spheres at an
economical 50% concentration. |
|
BINDZIL® 9950 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. |
| Forms
3D gels - |
Can be gelled with
Wesol D30 colloidal
alumina and refractory fibers to form thick fibrous coatings. |
| Rigidizes
Better - |
Larger particles
soak in farther and giver stronger, harder rigidized products. |
| Flocs
with Cationic Starch - |
Negative surface
charge flocs cationic starch and refractory fibers together to form a
three-dimensional floc for good product strength. |
