| Wesil MB | |
| Binder system for mineral wool fibers | |
| Wesil MB is a complete floccing and bonding system developed specifically for mineral wool fibers. Wesil MB’s aluminosilicate binder and fibrous high alumina fillers form strong bonds with mineral wool yielding superior hardness and strength. Traditional colloidal silica-starch systems do not bond well to mineral wool resulting in soft and weak spots. Wesil MB is the optimum system for consistently higher standards and durability in mineral wool boards and shapes. | |

Bonds Strongly to Mineral Wool - |
Uniquely able to form strong bonds with mineral wool fibers, yielding hard, strong boards and shapes. |
| Better Fired Strength - | More inorganic binder creates better fired strength |
| More Uniform Product - | Master batching creates more consistent binder ratios and enhanced product integrity. |
| No Cristobalite - | Completely cristobalite free at use temperature, eliminating a common source of thermal shrinkage problems and health related concerns. |
