Brief introduction:
Tung Oil is fineness dry oil whose viscidity and adhesive force are strong, it resists acid, alkali, insulates, it is also antiseptic, antirust, heat-resisting and cold-resistant. It is widely used in freights and ships, mechanism, architecture, national defense, leather, printing, electric, plastic, artificial rubber, medicine industries and departments etc. Tung Oil is a well-known production in Guizhou , planting Tung tree has a long history here, the seeds have large quantity and high fine quality, and the ratio of oil containing reaches 46%, the producing ratio is high. The oil is clean and transparent, its speed of drying is fast, the specific gravity is light, fragrance is dense, and luster is fine. As a result of the sample test of State Import & Export Commodity Inspection & Quarantine Bureau, every rationalize indices reaches the first class export Tung Oil standard, and it also was awarded the Fine Quality Production Honorary Certificate by the MOFTEC. Per year output is approximate 20,000 tons.
