Features Of Dow DOWSIL RTV-C Silicone Adhesive

  1. Room-temperature vulcanizing (RTV) silicone adhesive with rapid tack-free time for accelerated production cycles.

  2. Excellent adhesion to challenging substrates including metals, plastics, glass, and painted surfaces without primer.

  3. Wide service temperature range from –55 °C to 200 °C for reliable performance in extreme thermal environments.

  4. High flexibility and elongation (>150%) to absorb mechanical stress and accommodate thermal expansion mismatches.

  5. UL 94 HB flammability rating and low smoke emission, supporting safety-critical applications.

Typical Applications Of Dow DOWSIL RTV-C Silicone Adhesive

  1. Aerospace component bonding and sealing, including avionics housings and interior trim assemblies.

  2. Automotive powertrain and sensor mounting where vibration resistance and thermal cycling stability are required.

  3. Industrial electronics encapsulation and potting of control modules exposed to humidity and temperature extremes.

  4. LED lighting fixture assembly, providing optical clarity retention and long-term UV resistance.

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