Wesolok D
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.


Wesolok D offers these advantages

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.
