The oil is amber-coloured, and contains a high proportion of eleostearic acid. 

Uses:

Can be used as a timber finish and is widely used as a drier in varnishes and paints. Pure Tung Oil is also a most effective seal for concrete bench-tops, floors, slate/ stone, terracotta, mud brick (adobe), and other similar constructions. 

The finish is more suited for interior or exterior/protected use than fully exposed exterior, due to a lack of UV resistance.
