Linseed oil is widely used as a drying oil in paints and varnishes due to its ability to polymerize into a solid form when exposed to air. It is a key ingredient in oil-based paints, providing a durable and protective finish for wood surfaces. In woodworking, it is applied as a natural wood finish to enhance the grain and provide a water-resistant coating. Additionally, linseed oil is used in the production of linoleum flooring and as a binder in artists' oil paints. Its application extends to the manufacturing of putty and as a lubricant in some industrial processes.
