Features Of Wacker ELASTOSIL 9100 N One-Component Silicone Sealant

  1. Neutral-cure, acetoxy-free formulation ensures excellent compatibility with sensitive substrates including metals, plastics, and painted surfaces.

  2. Exceptional long-term elasticity and permanent flexibility over a wide temperature range (–60 °C to +200 °C).

  3. Low modulus design provides high movement capability (±50 % joint movement) without stress buildup.

  4. Excellent resistance to weathering, UV radiation, ozone, and aging — maintains performance for decades in outdoor exposure.

  5. Ready-to-use one-component system with moisture-curing mechanism; no mixing required and simple application via standard cartridge gun.

Typical Applications Of Wacker ELASTOSIL 9100 N One-Component Silicone Sealant

  1. Sealing and bonding in photovoltaic module assembly, including frame-to-glass and junction box adhesion.

  2. Encapsulation and edge sealing of LED lighting components and electronic housings.

  3. Structural and non-structural glazing in architectural façades and curtain wall systems.

  4. Sealing of precision instruments, medical devices, and cleanroom-compatible equipment.

  5. Bonding and sealing in automotive electronics and EV battery enclosures requiring thermal stability and electrical insulation.
