CYCLOTENE chemists

CYCLOTENE* advanced electronics resins from The Dow Chemical Company are high-purity polymer solutions that have been developed for microelectronics applications. The resins are derived from B-staged bisbenzocyclobutene-based (BCB) monomers and are formulated as high-solids, low-viscosity solutions.

Notable properties of the resins include:

  • Low dielectric constant
  • Low loss at high frequency
  • Low moisture absorption
  • Low cure temperature
  • High degree of planarization
  • Low level of ionics
  • High optical clarity
  • Good thermal stability
  • Excellent chemical resistance
  • Good compatibility with various metallization systems
  • Less than 5% shrinkage during cure
