Glastion is a clear, durable sealer that prevents moisture from entering the exposed glass edge, the most common cause of perimeter delamination. Glastion forms a physical barrier between the structural sealant and the PVB interlayer. The product’s thick consistency allows it to in-fill imperfections at the edge, including the groove formed between two panes in the laminating process. Glastion has anti-corrosion properties for the protection of mirror backing metals. The versatility of the product allows it to be easily applied at the time of manufacture or upon installation.
