Dow Aromatics Co-Products

Hydrocarbon Resins

Hydrocarbon-based resins are used in applications such as print inks, adhesives, (polymer-) additives and coatings. Following are the main groups of hydrocarbon resins:

  • Aliphatic resins, based on C5 or dicyclopentadiene (DCPD) as raw materials
  • Aromatic resins, based on C9 aromatic components such as vinyltoluenes or indenes
  • Combinations of C5/C9 feedstocks

Dow supplies both C5 as well as (aromatic-) C9 raw materials. See the table below to review Dow Aromatics Co-Products that are used in the production of hydrocarbon resins.
