| Wesolok D | |
| Highly dispersible large-particle colloidal alumina for fiber binding | |
| Wesolok D is a highly dispersible, larger particle size colloidal alumina powder. It is used with cationic starch for vacuum forming ceramic fiber shapes. Wesolok D is used for bonding fiber shapes that are more refractory and safer to use than colloidal silicas. | |
|
|
|
| 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. |
