Long Oil

Long Oil refers to oils with a high content of unsaturated fatty acids, particularly linoleic and linolenic acids, commonly derived from drying oils such as linseed, soybean, or safflower oil. These oils have extended drying times and are used in various industrial applications where slow curing and flexible film formation are desired. Long oil is a key component in producing long oil alkyd resins, which are widely used in coatings, paints, varnishes, and printing inks due to their excellent adhesion, flexibility, and durability.

Long Oil (45/55)

Long Oil (45/55) is a type of alkyd resin characterized by its high oil content—typically 45% oil to 55% resin—which results in a flexible, durable film once cured. It is widely used as a binder in oil-based paints, varnishes, and industrial coatings due to its excellent adhesion, gloss retention, and water resistance. The "long oil" designation refers to the proportion of drying oil (usually linseed, soybean, or tall oil) in the resin formulation, which makes it particularly suitable for air-drying applications. This resin is most commonly used in architectural coatings, primers, anticorrosive coatings, and decorative finishes. Its slow drying nature offers better flow and leveling, especially for brushing applications. It is also valued for its compatibility with a wide range of pigments and solvents.
