Linseed Oils are drying oils, used to control color, prevent over thinning with solvent and maintain the flexibility of the paint film. They can be thinned with turpentine.Cold-Pressed Linseed Oil is used to reduce the consistency of oil colors, increase gloss and transparency and reduce brush marks.Refined Linseed Oil is an alkali-refined, pale oil that reduces oil color consistency, increases gloss and transparency and slows drying rate.Thickened Linseed Oil is a pale, refined oil of syrupy consistency that increases flow of colors and speeds drying.Linseed Stand Oil slows drying but imparts a tough, elastic finish. When mixed with turpentine it improves the flow of oil color.
