mineraalitärpättiin

Mineraalitärpätti, often referred to simply as mineral spirits or white spirit, is a petroleum-derived solvent used primarily as a cleaning agent and a thinner for oil-based paints, varnishes, and lacquers. It is a mixture of aliphatic and alicyclic hydrocarbons, with a small amount of aromatic hydrocarbons. The exact composition can vary depending on the manufacturer and the specific grade of the product.

Historically, it was a common substitute for turpentine, hence the name. While it shares some similar properties with turpentine, such as its solvency, mineral spirits are generally less volatile and have a milder odor. This makes them a popular choice in both professional and DIY applications for cleaning brushes, tools, and surfaces contaminated with oil-based substances.

In addition to its use in the paint industry, mineral spirits are also employed in degreasing metal parts, removing adhesives, and as a component in some cleaning solutions. Its effectiveness lies in its ability to dissolve oils, greases, and other organic materials. When used as a paint thinner, it helps to reduce the viscosity of oil-based paints, making them easier to apply evenly. It evaporates relatively slowly, allowing for a smoother finish. Proper ventilation is recommended when working with mineral spirits due to their flammable nature and potential respiratory irritants.
