Features Of Dow DOWSIL 1200 OS r UV Traceable Primer

  1. UV-traceable formulation enables real-time visual verification of primer coverage during application using standard 365 nm UV lamps.

  2. One-component, solvent-based silicone primer offering rapid room-temperature cure without requiring moisture or heat activation.

  3. Excellent adhesion promotion for silicone elastomers (e.g., HTV and LSR) on challenging substrates including metals, plastics, and glass.

  4. Low-viscosity liquid ensures uniform coating via spray, dip, or brush application with minimal overspray and consistent film thickness.

  5. Compatible with automated manufacturing lines and validated for use in medical device and automotive assembly processes.

Typical Applications Of Dow DOWSIL 1200 OS r UV Traceable Primer

  1. Adhesion priming of liquid silicone rubber (LSR) onto stainless steel housings in implantable medical devices.

  2. Surface preparation for high-voltage silicone insulators prior to overmolding with silicone elastomers.

  3. Bonding enhancement between silicone gaskets and polycarbonate or PBT enclosures in automotive lighting assemblies.

  4. Priming of metal substrates in consumer electronics for silicone-to-metal sealing applications requiring process traceability.
