Features Of Dow Corning 18 Silicone Resin

  1. High thermal stability with continuous service up to 200 °C.

  2. Excellent electrical insulation properties across wide temperature and frequency ranges.

  3. Good adhesion to metals, glass, and cured silicone elastomers without priming.

  4. Solvent-based formulation (xylene/toluene blend) enabling easy application by dipping, spraying, or brushing.

  5. Cures at elevated temperatures to form a hard, transparent, non-tacky film with low internal stress.

Typical Applications Of Dow Corning 18 Silicone Resin

  1. Electrical insulation coating for magnet wire and coil windings.

  2. Protective overcoat for high-temperature sensors and electronic components.

  3. Binding agent in high-temperature abrasive wheels and refractory composites.

  4. Surface treatment for fiberglass and ceramic substrates prior to metalizing or laminating.

  5. Matrix resin in specialty high-heat gasketing and sealing compounds.
