Evaporation rates of solvents
Webremove both solvent- and water-soluble dirt. Mineral Spirits, Naphtha and Turpentine The two most widely used finishing solvents are mineral spirits and naphtha. For our purposes, the principal differences between the two are evaporation rate and oiliness. Naphtha evaporates faster than mineral spirits and is “drier,” that is, less oily ...
