|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.|
|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.
