Natural Oils and Waxes Used in Wood Finishing

Natural oils are primarily plant-derived. Certain drying oils penetrate the wood surface and cure when exposed to oxygen. Tung oil, linseed oil, soybean oil, walnut oil, and sunflower oil are commonly used in wood finishing formulations. However, each oil's chemical structure and curing behavior directly impact performance and durability.

Extracted from Tung tree seeds native to Vietnam, Southern China, and Myanmar, Tung oil is a fast-curing natural oil used for centuries to protect and finish wood. Historically used in China to waterproof wooden ships, Tung oil deeply penetrates the wood grain to highlight natural character while building protection from within. Tung oil can also be blended with other drying oils and resins to enhance surface defense. L.Co combine Tung oil with blown linseed oil and soy-based resin. Applied in multiple thin coats, this system maximizes surface durability

Cold-pressed from flaxseeds, linseed oil is another widely used drying oil. Upon curing, it forms a clear polymer matrix inside and on the wood, deepening its natural tone. Drying speed and overall performance vary based on processing methods and oil grade.

Waxes are formulated into finishes to improve surface feel, sheen, and stain resistance. • Beeswax: Delivers a smooth, satin feel and natural sheen. Due to its soft nature, it is best suited for low-wear applications. • Carnauba Wax: Harder than beeswax, ideal for boosting surface hardness, gloss, and abrasion resistance. • Candelilla Wax: A relatively hard plant-based wax used to adjust formulation firmness and tactile finish.

• Shellac: Solvent-soluble and film-forming upon drying. Commonly used for fine furniture, woodworking, and antique restoration. • Rosin (Pine Resin): Blended with oils to fine-tune hardness, sheen, and film formation.

Oils and waxes are frequently combined to leverage their dual benefits: oils penetrate and cure within the wood grain to enhance color, while waxes add smooth tactile feel and surface resistance. Formulations typically blend Tung or linseed oil with beeswax, carnauba, or candelilla. The precise ratio determines hardness, sheen, dry time, and maintenance requirements.

Selecting the right finish depends on wood species, wear levels, moisture exposure, aesthetic goals, and application methods. For industrial manufacturing, key considerations include dry time, coverage, color stability, and batch-to-batch consistency. Over the years, L.Co has developed plant-based finishing systems engineered for seamless factory integration and real-world production demands.
