Features Of Wacker ELASTOSIL 4000 One-Component Silicone Sealant

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

  2. Low modulus formulation provides high elasticity and superior joint movement capability (±50%).

  3. Excellent resistance to UV radiation, ozone, weathering, and extreme temperatures (–60 °C to +200 °C long-term).

  4. Acetoxy-cure chemistry enables rapid surface cure and strong crosslinking in ambient humidity conditions.

  5. Non-corrosive to sensitive substrates including copper, brass, and aluminum alloys.

Typical Applications Of Wacker ELASTOSIL 4000 One-Component Silicone Sealant

  1. Structural glazing and façade sealing in architectural curtain walls.
