Mobile Sand Wash Equipment for Sale

The requisite propertiesand the organic vehicles required to produce them are well known to those skilled in the art of making inks, paints and lacquers. Typical vehicles include mixtures of two or more of the following ingredients: methyl ethyl ketone, cyclohexanone, ethyl acetate, amylacetate, Cellosolve, butanol, nitrobenzene, toluene, xylene, petroleum ether, chloroform, carbon tetrachloride,- various terpenes, such as pinene, dipentene, dipentene oxide, and the like, essential oils, such as oils of lavender, rosemary, aniseed,mobile sand washing machine, Sassafras, Wintergreen, fennel and turpentine, Assyrian asphalt, various rosins and balsams, and synthetic resins.
