ADSEAL 4580 is a professional-grade, one-component neutral cure silicone sealant designed for long-lasting weathersealing and flexible adhesion in residential, commercial, and industrial settings. It adheres to glass, aluminum, masonry, metal, wood, fiberglass, and some plastics—making it ideal for windows, doors, siding, control joints, roofing, and more.

Formulated for excellent UV resistance and low VOC emissions, ADSEAL 4580 performs reliably in both indoor and outdoor environments and meets ASTM C920, AAMA 802/805, and GREENGUARD GOLD certifications. It cures to a durable, non-sagging, elastic rubber and is compatible with sealed units and coated materials. Application is possible at temperatures as low as -29°C (-20°F), and the product can be tooled for a clean, professional finish.

Available in 304ml cartridges, 600ml sausages, pails, and drums. Always conduct adhesion testing and refer to the TDS for surface prep and primer requirements.
