Wesol Q20
Colloidal alumina rigidizer
Wesol Q20 rigidizer is a colloidal alumina dispersion for superior rigidizing of refractory fiber shapes. Wesol Q20 offers many advantages over colloidal silica sols including increased safety, lower electrolytes, lower reactivity at high temperatures, and less migration to the surface on drying. Wesol Q20 can be applied by spraying, rolling, brushing, or dipping, depending on ease of application and the degree of rigidizing needed.

Wesol Q20 offers these advantages

Rapid, Deeper Absorption — Larger particle size and low viscosity mean that Wesol Q20 absorbs rapidly and deeply for thorough rigidizing, even of thick shapes of two or more inches.
Withstands Higher Temperatures — High purity and low  reactivity yields greater refractoriness at high temperatures.

Reduces Surface Migration — This rigidizer has less tendency to migrate to the surface upon drying, resulting in a more uniform product.

Easy to Use — Completely dispersed at the maximum concentration so no mixing equipment is required.

No Cristobalite — Completely cristobalite free at use temperature eliminating a common source of thermal shrinkage problems and health related concerns.
