Wesol D30
High concentration colloidal alumina rigidizer
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.

Wesol D30 offers these advantages

Temperature Grade
1700°C (3092°F).
Coverage
100 – 200 square feet per gallon
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
This rigidizer has less tendency to migrate to the surface upon drying, resulting in a more uniform product.
Easy to Use
Pre-dispersed sol means no mixing required for a quick convenient process.
No Cristobalite
Completely silica-free, eliminating a common source of thermal shrinkage problems and health related concerns.
