| Wesolok D |
| More dispersible
large-particle colloidal alumina for rigidizing |
| 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 water at 20 to 30%
concentration to give stable colloidal alumina sols for rigidizing fiber
shapes that are more refractory and safer to use than colloidal silicas. |

Wesolok D offers these advantages
|
|
|
| Fast
Dispersing - |
Alumina sols of
20-30% concentration can easily be prepared with minimal mixing. |
| 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. |
| Rapid,
Deeper Absorption - |
The larger particle
size, with its lower surface change and viscosity, absorbs rapidly and
deeply for thorough rigidizing. |
| No
Cristobalite - |
Completely
cristobalite free at use temperature, eliminating a common source of
thermal shrinkage and health-related concerns. |
