| Wesolok D |
| More dispersible
large-particle colloidal alumina for fiber binding |
| Wesolok D
alumina rigidizer is a more dispersible, larger particle size
colloidal alumina than regular Wesolok.
It is a powder, ready for fast dispersion in fiber slurries for bonding
fiber shapes that are more refractory and safer to use than colloidal
silicas. |
|
Wesolok D offers these advantages
|
|
|
| No
pre-dispersing or aging - |
Can be added dry to
vacuum forming fiber slurries without pre-dispersing or aging, saving
extra steps and equipment costs. |
| Withstands
Higher Temperatures - |
High purity alumina
provides low reactivity and can be used to replace colloidal silica where
greater refractoriness at use temperatures is required. |
| Flocs
with Cationic Starch - |
The lower surface
charge of the alumina particles enables them to floc successfully with
cationic starch. |
| No
Cristobalite - |
Completely
cristobalite free at use temperature, eliminating a common source of
thermal shrinkage and health-related concerns. |
