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.


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.
