Features Of Wacker ELASTOSIL N9111 BLACK One-Component Silicone Sealant

  1. Fast room-temperature curing via moisture-induced condensation reaction, enabling efficient production line integration.

  2. Excellent adhesion to common substrates including glass, aluminum, stainless steel, and painted surfaces without primer.

  3. High elasticity and permanent flexibility with elongation at break >400%, maintaining seal integrity under dynamic stress.

  4. Outstanding resistance to weathering, UV radiation, ozone, and extreme temperatures (–60 °C to +200 °C short-term).

  5. Low volatile organic compound (VOC) content, compliant with stringent industrial hygiene and environmental requirements.

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

  1. Sealing and bonding in automotive lighting assemblies (headlamps, tail lamps, sensor housings).

  2. Encapsulation and edge sealing of photovoltaic modules and solar panel frames.

  3. Structural glazing and perimeter sealing in architectural curtain wall systems.

  4. Electronics housing assembly requiring EMI-shielding-compatible black silicone seals.

  5. Industrial equipment gasketing where thermal stability and non-staining performance are critical.
