Wesil CS
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.

Wesil CS offers these advantages

Significantly Reduced Costs
Typically reduces formula costs 30-40% below colloidal silica/starch systems.
No More Pre-dissolving or 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.
