Any vegetable or fish oil that does not dry or form a film, even on long exposure to air. Nondrying oils have a high degree of saturation, which is indicated by a low Iodine number (80 - 100). Nondrying oils are primarily used in food products (coconut, corn, olive, etc.) but some are used as plasticizers with drying oils and with natural and synthetic resins. Fish oils are sometimes used in industrial paints.
