What is White Spirit?
White Spirit or mineral spirits, also known as mineral turpentine, turpentine substitute, petroleum spirits, solvent naphtha (petroleum), var-sol, Stoddard solvent, or, generically, “paint thinner”, is a petroleum-derived clear, transparent liquid used as a common organic solvent in painting and decorating.
A mixture of aliphatic and alicyclic C7 to C12 hydrocarbons, white spirit is used as an extraction solvent, as a cleaning solvent, as a degreasing solvent and as a solvent in aerosols, paints, wood preservatives, lacquers, varnishes, and asphalt products. The main uses of the total white spirit consumption is used in paints, lacquers and varnishes. White spirit is the most widely used solvent in the paint industry. In households, white spirit is commonly used to clean paint brushes after use.
white spirit uses:
White Spirit is a petroleum distillate used as a paint thinner and mild solvent. In industry, mineral spirits are used for cleaning and degreasing machine tools and parts, and in conjunction with cutting oil as a thread cutting and reaming lubricant.
Mineral spirits are an inexpensive petroleum-based replacement for the vegetable-based turpentine. It is commonly used as a paint thinner for oil-based paint and cleaning brushes, and as an organic solvent in other applications. Mineral turpentine is chemically very different from turpentine, which mainly consists of pinene, and it has inferior solvent properties.Artists use mineral spirits as an alternative to turpentine since it is less flammable and less toxic. Because of interactions with pigments in oil paints, artists require a higher grade of mineral spirits than many industrial users, including the complete absence of residual sulfur.
Mineral spirits were formerly an active ingredient in the laundry soap Fels Naptha, used to dissolve oils and grease in laundry stains, and as a popular remedy for eliminating the contagious oil urushiol in poison ivy. It was removed as a potential health risk.
Mineral spirits are often used inside liquid-filled compasses and gauges.
Mineral spirits are also used for re-gripping golf clubs. After the old grip is removed, the mineral spirits are poured into the new grip and shaken. After the mineral spirits are poured on, the new underlying tape and the new grip are slid on. After an hour of drying out, the new grip and club are ready to use.
Mineral spirits have a characteristic unpleasant kerosene-like odor. Chemical manufacturers have developed a low odor version of mineral turpentine which contains less of the highly volatile shorter hydrocarbons. Odorless mineral spirits are mineral spirits that have been further refined to remove the more toxic aromatic compounds, and are recommended for applications such as oil painting, where humans have close contact with the solvent.
In screen printing (also referred to as silk-screening), mineral spirits are often used to clean and unclog screens after printing with oil-based textile and plastisol inks. They are also used to thin inks used in making monoprints.
Although not normally marketed as a fuel, white spirit can be used as an alternative to kerosene in portable stoves, since it is merely a light grade of kerosene.It cannot be used as an alternative to white gas, which is a much more volatile gasoline-like fuel.
White spirits are also a major ingredient in some popular automotive fuel/oil additives, such as Marvel Mystery Oil, as they are capable of dissolving varnish and sludge buildup.
Mineral spirits are also commonly used for cutting fluid in ultraprecision lathes (commonly referred to as diamond turning machines).
