Linseed oil is what is called a drying oil. It has been used as a binder in paints for many centuries. It can be hot-pressed / cold-pressed and refined, as well as heated and treated with various techniques so that its properties change.
In the old days it was wind turbines that produced the linseed oil, today it is done with modern machines.
Linseed oil dries by absorbing oxygen from the air. It causes it to polymerize and form a film. Linseed oil does not form a closed surface, but lets the substrate "breathe" so therefore linseed oil is good for treating woodwork. Because while the oil penetrates the wood and protects, it maintains the wood's own ability to absorb and release water as needed. In other words, the wood retains its diffusion openness. It provides a more sustainable construction where the materials can work together, and thus last longer.
It is advantageous to add fungicide to the linseed oil for outdoor use to reduce the possibility of mold on the surface. Linseed oil can be used as a main binder or co-binder in various types of paints due to its drying properties. Linseed oil is very common for priming raw wood with, either as a final treatment or as a pre-primer before a possible finishing with linseed oil paint.
Linseed oil can also be used to strengthen emulsion paints, glue paints, casein paints and the like.
