Wesil HT
High temperature system for molten metal contact
Wesil HT is a complete refractory fiber floccing and bonding system designed for thermocouple shields. Wesil HT contains a heat-setting proprietary binder for green hardness, and refractory additives that allow conventional refractory ceramic fibers to withstand molten steel contact at 2700oF. 

Wesil HT offers these advantages

Significantly Reduced Costs - Typically reduces formula costs 30-40% below colloidal alumina/starch systems.
Hard, strong fiber shapes - Proprietary resin sets at drying temperatures (250oF) to give dense, hard green fiber shapes.
Reduces Fluxing and Shrinkage - Alumina coating of fibers maintains their integrity at high temperatures, allowing for successful operation at temperatures several hundred degrees higher than normal..
