  • DCO is lighter than Tung Oil (Tung Oil from About.com) and Linseed Oil (Linseed Oil from Wikipedia). DCO can be used to improve the quality of house paints, enamels, caulks, sealants and inks. This oil also works well in clear varnishes and hard finish coatings.
  • DCO can be converted to dehydrated castor fatty acid by hydrolysis and distillation. This (dehydrated castor fatty acid) is used in the manufacture of alkyd resins, coatings, appliance finishes, primers and inks.
