Your Oil. Your Recipe. The Right Contract Manufacturer.
Linseed Oil is a versatile and highly effective natural oil extracted from flax seeds, commonly used for a range of applications, from wood finishing to health supplements. In home care and industrial settings, it serves as a protective coating and preservative for wood and other porous materials, helping to nourish and seal surfaces while providing a natural luster. Linseed oil is prized for its ability to deeply penetrate materials, preventing cracking, warping, and drying out over time. It creates a breathable barrier, allowing moisture to escape while maintaining the integrity of the material. The oil is particularly valued for its environmental friendliness and non-toxic properties, making it a preferred option for eco-conscious consumers and businesses.

01 Types of Linseed Oil:
- Raw Linseed Oil: This is the most natural form, extracted without any additives or processing. It is slow-drying and penetrates deeply into wood, making it ideal for nourishing untreated surfaces. However, due to its slow drying time, it’s best suited for applications where longer drying periods are acceptable, such as restoring outdoor furniture or finishing porous surfaces.
- Boiled Linseed Oil: This type of linseed oil has been heat-treated or has drying agents added to accelerate the drying process. Boiled linseed oil is favored for applications that require quicker drying times, like wood finishing or sealing. It creates a durable, glossy finish while retaining the protective qualities of raw linseed oil, but with faster results.
- Polymerized Linseed Oil: Also known as stand oil, this type has been treated at high temperatures in the absence of air, resulting in a thicker, more durable oil. It dries harder and is often used in fine woodwork or flooring, where a stronger finish is necessary

02 Formulations of Linseed Oil:
- Pure Linseed Oil: This formulation is entirely natural and used where no chemical additives are preferred. It is highly penetrating and ideal for outdoor wood surfaces, like decks and fences, where a natural protective layer is needed.
- Linseed Oil Varnishes: These are blends of linseed oil with resins or other hardening agents to create a tougher, more resilient finish. Linseed oil varnishes are perfect for interior woodwork, such as tables and cabinetry, where both protection and an aesthetic glossy finish are desired.
- Linseed Oil-Based Paints: Linseed oil serves as a base in many eco-friendly paints. These paints are less harmful to the environment, providing a durable, breathable coating for wood and metal surfaces. They are often used in historical restorations or by those looking for natural alternatives to synthetic paints.
- Linseed Oil Putty: Commonly used in glazing applications, linseed oil is mixed with chalk or other fillers to create putty. This formulation is ideal for sealing windows and repairing minor surface imperfections, providing a flexible yet long-lasting bond.
- Linseed Oil Emulsions: In some cases, linseed oil is emulsified for use as a cleaner or conditioning agent. These emulsions allow the oil to mix with water, making it suitable for more delicate applications, such as treating leather or conditioning softer woods that benefit from gentle nourishment.

03 Benefits of Linseed Oil:
Linseed oil offers several advantages when used in home care and industrial settings:
- Penetrating Action: Linseed oil’s ability to deeply penetrate wood and other materials helps protect from within, ensuring long-lasting durability.
- Non-Toxic: As a natural product, it is free from harsh chemicals, making it safe for use around the home, especially for surfaces that may come into contact with food or skin.
- Moisture Protection: It forms a breathable layer that repels water while allowing trapped moisture to escape, preventing rot, mold, and other moisture-related damage.
- UV Resistance: Linseed oil offers some protection against UV rays, slowing down the fading and degradation of wood exposed to sunlight.
- Versatility: From preserving outdoor wooden furniture to being a key ingredient in eco-friendly paints and varnishes, linseed oil is adaptable to a variety of uses.
