Features Of Wacker ELASTOSIL N9111 GREY One-Component Silicone Sealant

  1. Room-temperature vulcanizing (RTV) silicone sealant with neutral cure chemistry — acetoxy-free and non-corrosive to metals and sensitive substrates.

  2. Excellent adhesion to common construction and industrial substrates including glass, aluminum, ceramics, and painted surfaces without primer.

  3. High elasticity and permanent flexibility — maintains >200% elongation at break after full cure, resisting cracking under thermal or mechanical stress.

  4. Weather-resistant formulation — UV stable, ozone resistant, and capable of long-term outdoor exposure without degradation.

  5. Low volatility and low odor — compliant with stringent indoor air quality requirements for occupied spaces.

Typical Applications Of Wacker ELASTOSIL N9111 GREY One-Component Silicone Sealant

  1. Sealing and bonding in architectural glazing systems, including structural and perimeter sealing of insulating glass units (IGUs).

  2. Joint sealing in façade construction — curtain walls, aluminum composite panels (ACP), and precast concrete cladding.

  3. Industrial assembly applications requiring durable, flexible bonds — control cabinets, LED lighting housings, and electronic enclosures.

  4. Automotive component sealing — interior trim assemblies, sensor housings, and non-structural gasketing where vibration resistance is critical.

  5. Maintenance and repair sealing in HVAC systems, cleanrooms, and pharmaceutical facility infrastructure.
