Features Of Wacker ELASTOSIL N288 One-Component Silicone Sealant

  1. Room-temperature vulcanizing (RTV) silicone sealant with neutral cure chemistry — acetoxy-free, low odor, and non-corrosive to substrates.

  2. Excellent adhesion to common construction and industrial materials including glass, aluminum, ceramics, and painted surfaces without primer.

  3. Outstanding resistance to weathering, UV radiation, ozone, and temperature extremes (–60 °C to +200 °C continuous).

  4. Good elasticity and permanent flexibility after curing — maintains sealing integrity under dynamic joint movement.

  5. One-component formulation enables simple, tool-free application and consistent performance without mixing or pot-life constraints.

Typical Applications Of Wacker ELASTOSIL N288 One-Component Silicone Sealant

  1. Sealing and bonding in architectural glazing systems, including structural and perimeter sealants for curtain walls.

  2. Industrial assembly of electronic enclosures, sensors, and LED lighting housings requiring reliable environmental protection.

  3. Automotive component sealing for interior trim, lighting modules, and non-structural gasketing applications.

  4. General-purpose sealing in HVAC equipment, appliances, and white goods where thermal stability and chemical inertness are critical.

  5. Repair and maintenance sealing in transportation and machinery where resistance to vibration and aging is essential.
