Silicone: 799

Silicone sealants are the preferred method for weather-sealing these joints. However, anodized aluminum, powder-coated steel, and composite panels can be difficult substrates. Silicone 799 ensures that the sealant remains adhered for decades, preventing water ingress which could lead to structural rot or mold growth within the building envelope.

Certain 799 formulations are 100% silicone with no added biocides or fungicides, making them safe for aquatic life and plants. The neutral cure prevents off-gassing that can kill fish. silicone 799
