Features Of Wacker ELASTOSIL 5000 One-Component Silicone Sealant

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

  2. Low modulus formulation provides high elasticity and superior joint movement capability (±50% according to ASTM C719).

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

  4. Acetoxy-cure chemistry delivers fast surface cure and reliable deep-section curing under ambient humidity conditions.

  5. Non-corrosive to most substrates and compatible with common architectural and industrial assembly processes.

Typical Applications Of Wacker ELASTOSIL 5000 One-Component Silicone Sealant

  1. Structural and perimeter sealing of insulating glass units (IGUs) in curtain walls and façades.

  2. Joint sealing in aluminum composite panels (ACP), metal cladding systems, and precast concrete façades.

  3. Sealing and bonding of sanitary installations, including shower enclosures, bathtubs, and washbasins.

  4. Industrial gasketing and vibration-damping applications in transportation and machinery housings.

  5. Electrical encapsulation and potting where thermal stability and dielectric performance are required.
