| Wesolok |
| Colloidal alumina
for fiber bonding |
| Wesolok alumina binder
is a high purity boehmite (aluminum oxide hydroxide) powder ready for
dispersion in water at 5 to 10% concentration to give stable colloidal
alumina sols for bonding refractory fiber shapes. It can be flocced onto
fibers, like colloidal silica, with Westar+
flake corn starch. |

Wesolok offers these advantages
|
|
|
| Smaller
Particle Size Readily Flocs to Fibers - |
Wesolok has a
moderate cationic charge which flocs well with all starches, and works
best with cationic starches like Westar+. |
| Withstands
Higher Temperatures - |
High purity alumina
provides for low reactivity and can be used to replace colloidal silica
where greater refractoriness at use temperatures is required. |
| No
Cristobalite - |
Completely
cristobalite free at use temperature, eliminating a common source of
thermal shrinkage and health-related concerns. |
