Fast dry products promote efficient water release during the firing process while ensuring no damage to the material structure.
Fast dry products also offer high corrosion resistance, extended service lives, energy savings, reduced maintenance time and maximum trough availability that customers have come to expect from Saint-Gobain Performance Ceramics & Refractories’ products.
Does this special binder exhibit any side effects?
No. Unlike other non-cement binders (such as colloidal silica), this novel system does not introduce any deleterious compounds to the castable, which could potentially inhibit its corrosion and oxidation resistance.
How do Saint-Gobain Performance Ceramics & Refractories’ fast dry products reduce drying issues?
Fast dry castables’ specialized binder system does not generate hydrates in the structure as it dries. Its permeability is also hundreds of times higher than conventional trough and runner castables. These characteristics mean that it is possible to perform repairs with significantly reduced drying schedules.
Why is the drying step such an important issue?
Most castables utilize cement as the binding agent - well known for its high strength development via hydrate formation.
However, as dehydration occurs during drying, there is a risk that the pressure generated by the water vapor will damage the refractory structure.
Therefore, it is important that sufficient time and care is taken during the drying process when conducting refractory repairs.
