Features Of Wacker ELASTOSIL E70 One-Component Silicone Sealant

  1. Room-temperature vulcanizing (RTV) silicone sealant with excellent adhesion to glass, aluminum, ceramics, and most common construction substrates.

  2. Neutral-cure chemistry—releases methanol during cure, minimizing corrosion risk to sensitive metals and electronics.

  3. High elasticity and permanent flexibility after curing, maintaining performance across temperature ranges from −40 °C to +150 °C.

  4. Excellent resistance to UV radiation, ozone, and weathering—ideal for long-term outdoor exposure.

  5. Low modulus formulation provides superior stress relief in dynamic joints and accommodates substantial movement without loss of seal integrity.

Typical Applications Of Wacker ELASTOSIL E70 One-Component Silicone Sealant

  1. Structural glazing and perimeter sealing of insulating glass units (IGUs) in façade systems.

  2. Sealing expansion joints and curtain wall assemblies in commercial and high-rise buildings.

  3. Weatherproofing and bonding of solar panel frames, PV module enclosures, and rooftop mounting systems.

  4. Electrical encapsulation and housing sealing in outdoor lighting, sensors, and control cabinets.

  5. General-purpose sealing of non-porous substrates in architectural metalwork and prefabricated building elements.
