|High concentration colloidal alumina for fiber bonding and rigidizing|
|Wesol D30 colloidal alumina rigidizer is a high concentration, large particle size sol for superior rigidizing of refractory fiber shapes. Wesol D30 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.|
|Rapid, Deeper Absorption —||Larger particle
size and low viscosity mean that Wesol D30 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 —||
has less tendency to migrate to the surface upon drying, resulting in a
more uniform product.
|Ready to Use —||
Wesol D30 is completely dispersed at the maximum concentration so no mixing equipment is required
|No Cristobalite —||
free at use temperature eliminating a common source of thermal shrinkage
problems and health related concerns.
