DOWSIL 983 Structural Glazing Sealant Base is designed for specialized use where dual structural and weatherseal applications are desired for factory glazing and curtainwall production. Once cured, this structural sealant forms a durable, flexible, watertight bond that can be warranted for 20 years and used in 25% movement weatherseal applications. It has excellent unprimed adhesion to glass, alodine, and anodized aluminum, although DOWSIL Primer-C OS is recommended for fast and consistent adhesion, especially to high-performance substrates approved for architectural structural glazing applications. Sustainability: Low embodied carbon DOWSIL Silicone. Project specific DOW Carbon Neutrality Certificate on request. Externally verified carbon neutrality according to PAS 2060. Carbon Neutrality with DOW Carbon "INSETS" and reduce carbon footprint. Green Building certification: contributes to getting additional credits.
