Wesil NS
No smoke aluminosilicate binder system
Wesil NS (no smoke) is a complete refractory fiber floccing and bonding system for use where a minimum of off-gassing is desired in the bonded product. Wesil NS is a dry binder containing cationic Wesolok alumina and a small amount of organic flocculent. This binder system produces firm, strong dried boards and shapes that don't give off fumes or smoke on contact with hot metal or open flame.

Wesil NS offers these advantages

Less Smoke and Whiter Color — Lower organic content for purer color and reduced off-gassing.

No More Cooking Starch — Contains pre-gelled cationic starch, eliminating time-consuming extra steps.

Greater 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.
