|Complete binder system for vacuum forming fibers|
|Wesil CS is a complete refractory fiber floccing and bonding system that replaces both colloidal silica and starch, saving the extra steps of dissolving and/or cooking the starch separately. It contains a cationic cold-water swelling corn starch blended at an optimum ratio with our proprietary aluminosilicate in a dry binder. Buffers are added to maintain proper pH for maximum strength products and reduced bacteria growth for better slurry life.|
|Significantly Reduced Costs —||Typically reduces
formula costs 30-40% below colloidal silica/starch systems.
|No More Cooking Starch —||Contains pre-gelled
cationic starch, eliminating time-consuming extra steps.
|Less Smoke and Whiter Color —||Lower organic content
for purer color and reduced off-gassing.
|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.
