High-Temperature Glass Sealant

Aremco-Seal™ 617 is a high-temperature, single part, water-based glass coating used to seal porosity in ceramics and refractories for applications to 1450°F in electrical and high-vacuum applications where hermeticity is required. Aremco-Seal™ 617 is easily applied by dipping, brushing or spraying and cleans up prior to curing with warm water. Curing is accomplished by setting at room temperature for 30 minutes then heating to 1600°F for an additional 30 minutes.
