Wesbond - Wesol D30

Wesol D30

Colloidal alumina for refractory fiber bonding

Wesol D30 alumina binder is a 30-weight-percent water-based dispersion of colloidal alumina. It can be used instead of colloidal silica in typical starch-flocced vacuum forming systems. Fiber shapes bonded with Wesol D30 are more refractory and safer to use than shapes bonded with colloidal silica.

Wesol D30 offers these advantages

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 silca free, eliminating a common source of thermal shrinkage problems and health-related concerns.

Flocs with cationic starch

Has a moderate cationic charge which works well with all starches, and especially well with a cationic starch like Westar+.
