Features Of Dow DOWSIL PR-1200 RTV Coat Silicone Elastomer

  1. Fast room-temperature vulcanization (RTV) with low-energy cure profile, enabling efficient line-speed processing.

  2. Excellent adhesion to diverse substrates including metals, plastics, glass, and painted surfaces without primers.

  3. High elongation (>300%) and outstanding flexibility over wide temperature range (–55 °C to +200 °C).

  4. Superior resistance to moisture, ozone, UV radiation, and thermal aging — ideal for long-term outdoor exposure.

  5. Low volatility and minimal outgassing, meeting stringent requirements for electronics and optical applications.

Typical Applications Of Dow DOWSIL PR-1200 RTV Coat Silicone Elastomer

  1. Protective conformal coating for printed circuit boards (PCBs) and electronic assemblies.

  2. Sealing and encapsulation of LED modules, sensors, and automotive lighting units.

  3. Edge bonding and stress-relief coating for flexible displays and touch panels.

  4. Moisture-barrier overcoat for photovoltaic backsheet laminates and solar module edge seals.

  5. Functional coating on medical device housings requiring biocompatibility support and sterilization resistance.
