| 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. | |

|
|
| 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. |
