Weber Turpenoid Slow Dry is a mild solvent with no harmful aromas and a very high (200°F/93°C) flashpoint, making it safer for studios and classrooms. Use it for thinning oil colors and modifying oil mediums. Offering very slow and complete evaporation, it allows for more open time when combined with other mediums. It's also great for cleaning brushes, painting knives, palettes, and other tools and accessories. Weber Turpenoid Light meets the California Air Resources Board (CARB) exemption for consumer products.
