| Colloidal silica for
bonding and rigidizing fibers |
| BINDZIL®
1440 is the most commonly used colloidal silica for bonding
refractory fibers and rigidizing refractory fiber shapes and boards. BINDZIL®
1440 is an economical 40% concentration silica sol of 14 nanometer
diameter amorphous silica spheres. The particles carry a slightly negative
surface charge with a high surface area to weight ratio for good floccing
with Westar+ and Westar+3
cationic starch. |
|
BINDZIL® 1440 offers these advantages
|
|
|
| Good
High Temperature Bonds - |
Colloidal silica
bonds withstand temperatures up to 2300oF with low shrinkage.. |
| Saves
Money - |
Economical 40%
concentration reduces freight and package costs over lower concentration
sols. |
| Flocs
with Cationic Starch - |
Negative surface
charge flocs cationic starch refractory fibers together to form a three
dimensional floc for good product strength. |
| Rigidizes
Effectively - |
Can be used diluted
or full strength for sealing or rigidizing of fiber-bonded shapes. |
