Tung Oil, also known as China Wood Oil, is one of the most important vegetable based drying oils in the world. Tung Oil is produced in China and South America. The South American oil is usually lighter in color and higher in price. Tung Oil has been used as a waterproofing material for shoes, umbrellas and silks. It has also been used in soap and varnish. Tung Oil has also used in the manufacturing of electronic circuit boards. Although other drying oils can be substituted for Tung Oil, it’s unique properties make it the preferred drying oil in the manufacture of paints, resins, coatings and inks. Tung Oil is excellent for finishing and waterproofing raw wood, concrete and wall board. Linseed Oil is the oldest known drying oil in the Western hemisphere. Its long standing use in certain applications has made its displacement by other drying oils nearly impossible. Linseed is used in the manufacturing of paints, varnishes, enamels, lacquers, stains, printing inks, furniture polish and wall boards. Oiticica Oil grows wild and only grows in Brazil. Oiticica Oil finds limited use as a substitute for Tung Oil or Linseed Oil when the price of either of these products prohibit their use. Oiticica Oil is much darker in color and is susceptible to transforming into a pasty, semi-solid state at room temperature. This requires heating prior to use. Dehydrated Castor Oil is lighter than Tung Oil or Linseed Oil. It 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. Dehydrated Castor Oil can be converted to Dehydrated Castor Fatty Acid by hydrolysis and distillation. It can be used I the manufacture of alkyd resins, can coatings, appliance finishes, primers and inks.
