Overview
DELI’s High Strength Structural Silicone Sealant 9900 (BN-9900) is engineered for high-performance outdoor glazing and exterior joint sealing. This paste-form structural adhesive is designed to deliver reliable long-term bonds across a wide range of substrates and weather conditions, making it ideal for windows, doors, facades, and other exterior assemblies.

What sets 9900 BN-9900 apart

• High solids content — Active Substance ≥ 37 ensures robust, durable joints that resist deformation under thermal cycling and wind-driven moisture.
• Extensive substrate compatibility — Bonds effectively to fiber, metal, wood, vitrified brick, glass, electronics, plastics, cement, stone, ceramics, paper, leather, rubber, resin, silicone, and more, enabling a single sealant for diverse assemblies.
• Triple sealing and waterproofing capabilities — Built to form a reliable, weather-tight seal that helps prevent leaks at exterior joints around windows and doors.
• Fast bonding for efficient workflows — Accelerates installation timelines without compromising long-term performance.
• Versatile curing options — Supports moisture cure, UV cure, room temperature cure, polymerization, and additional methods (hot melt, anaerobic, solvent evaporation, dual-component, thermal cure), giving you flexibility for on-site and factory settings.
• GB16776-2005 compliance — Manufactured to a recognized standard for structural silicone sealants, offering reassurance on quality and performance.
• Proven packaging and shelf life — 590ml per tube, with 20 tubes per carton; 1-year shelf life; optional warranty of 10–50 years for select projects.
