Features Of Wacker ELASTOSIL N2034 One-Component Silicone Sealant

  1. Room-temperature vulcanizing (RTV) silicone with excellent adhesion to glass, aluminum, ceramics, and most plastics without primer.

  2. Neutral-cure acetoxy chemistry delivering low odor and minimal shrinkage during cure.

  3. Good resistance to UV radiation, weathering, and temperature extremes (–50 °C to +180 °C continuous).

  4. High elasticity and permanent flexibility after full cure, maintaining seal integrity under dynamic joint movement.

  5. One-component formulation enabling simple, tool-free application and convenient storage stability (12 months unopened at 25 °C).

Typical Applications Of Wacker ELASTOSIL N2034 One-Component Silicone Sealant

  1. Sealing and bonding in architectural glazing systems, including structural and non-structural façade joints.

  2. Automotive lighting assembly — sealing headlamps, tail lamps, and sensor housings.

  3. Electronics encapsulation and potting for moisture-sensitive components and connectors.

  4. Industrial equipment housing seals requiring long-term environmental resistance and vibration damping.

  5. Medical device assembly where biocompatibility-compliant silicone adhesives are preferred for non-invasive applications.
