Drying Oil

Drying oil is a type of oil that hardens to a tough, solid film after a period of exposure to air. The oil hardens through a chemical reaction in which the components crosslink by the action of oxygen (not through the evaporation of water or other solvents).

Pronunciation

/draɪɪŋ ɔɪl/

Etymology

The term "drying oil" comes from the oil's unique property to dry and harden upon exposure to air.

  • Polymerization: The process by which drying oils harden.

Usage

Drying oils are used in paint and varnish and as a component of ink and putty. They are also used in the treatment of wood, especially in the manufacture of particle board. They are often heated or combined with other agents to improve their drying properties.

Health and Safety

Exposure to drying oils can cause skin irritation and may be harmful if swallowed or inhaled. Always use appropriate safety measures when handling these substances.
