Wesbond - Wesolok

Wesolok

Colloidal alumina for fiber bonding

Wesolok alumina binder is a high purity boehmite (aluminum oxide hydroxide) powder ready for dispersion in water at 5 to 10% concentration to give stable colloidal alumina sols for bonding refractory fiber shapes. It can be flocced onto fibers with Westar+ flake corn starch.

Wesolok offers these advantages

Smaller Particle Size Readily Flocs to Fibers

Wesolok has a moderate cationic charge which flocs well with all starches, and works best with cationic starches like Westar+.

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.

No cristobalite

Completely cristobalite free at use temperature, eliminating a common source of thermal shrinkage and health-related concerns.
