Features Of Wacker ELASTOSIL 7000 N One-Component Silicone Sealant

  1. Neutral-cure, acetoxy-free formulation ensures no corrosive by-products during curing — safe for sensitive substrates including metals and electronics.

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

  3. High elasticity and permanent flexibility after cure, maintaining seal integrity under dynamic joint movement and thermal cycling.

  4. Fast surface cure (tack-free in ≤30 min) and full cure at room temperature with moisture from ambient air.

  5. UV, ozone, and weathering resistant — suitable for long-term outdoor exposure without significant degradation.

Typical Applications Of Wacker ELASTOSIL 7000 N One-Component Silicone Sealant

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

  2. Automotive assembly for non-structural gasketing, lamp housing seals, and sensor mounting interfaces.

  3. Electronics encapsulation and potting of low-voltage components where electrical insulation and thermal stability are required.

  4. Industrial equipment assembly requiring vibration-damping, moisture-resistant seals on control panels and housings.

  5. Renewable energy applications, including sealing photovoltaic module frames and junction boxes.
