| Wesolok Q | |
| Highly dispersible colloidal alumina for fiber binding | |
| Wesolok Q alumina rigidizer is a non-dusting coarse powder ready for fast dispersion in fiber slurries 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. |
