|More dispersible large-particle colloidal alumina for rigidizing|
|Wesolok D alumina rigidizer is a more dispersible, larger particle size colloidal alumina than regular Wesolok. It is a powder, ready for fast dispersion in water at 20 to 30% concentration to give stable colloidal alumina sols for rigidizing fiber shapes that are more refractory and safer to use than colloidal silicas.|
|Fast Dispersing —||Alumina sols of
20-30% concentration can easily be prepared with minimal mixing.
|Withstands Higher Temperatures —||High purity alumina
provides for low reactivity and can be used to replace colloidal silica
where greater refractoriness at use temperatures is required.
|Rapid, Deeper Absorption —||The larger particle
size, with its lower surface change and viscosity, absorbs rapidly and deeply
for thorough rigidizing.
|No Cristobalite —||Completely cristobalite
free at use temperature, eliminating a common source of thermal shrinkage
and health-related concerns.
|Typical Physical Properties|
|pH (20% sol)||3 - 4|
|Average particle size (nm)||70|
|Concentration limit (sol)*||30%|
|Toxicity||Non-toxic. Non-hazardous, safe for spraying relative to inhalation; protect eyes from splashes and spray. See MSDS.|
|Packaging||Fiber drums, 400 lbs net, loose or 20 lb bags cartons, 60 lbs net.|
|*Higher concentrations form thixotropic gels on standing|
