Features Of Wacker ELASTOSIL 8510 One-Component Silicone Sealant

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

  2. Low modulus formulation providing high elasticity and long-term movement capability (±25% joint movement).

  3. Neutral-cure chemistry — acetoxy-free, non-corrosive to metals and sensitive substrates.

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

  5. Good electrical insulation properties and low volatile organic compound (VOC) emission.

Typical Applications Of Wacker ELASTOSIL 8510 One-Component Silicone Sealant

  1. Sealing and bonding in architectural glazing systems (e.g., structural and perimeter seals for curtain walls and windows).

  2. Electronics encapsulation and potting of sensors, LED modules, and control units requiring thermal stability and dielectric integrity.

  3. Automotive lighting assemblies, including headlamp and tail lamp sealing where optical clarity and long-term resilience are critical.

  4. Medical device housing assembly requiring biocompatibility-compliant materials and cleanroom-compatible processing.

  5. Industrial equipment gasketing and vibration-damping interfaces exposed to outdoor or harsh environmental conditions.
