What Is a Boiled Linseed Oil?
Boiled linseed oil (boiled oil) is an oxidized oil produced by boiling dry oil with metal oxides.
During the manufacturing process, dry oil, such as linseed oil, soybean oil, or EB oil, is heated with metal oxides like manganese, lead, or cobalt, while oxygen is blown in, maintaining a temperature of 120 to 150℃.
This process removes water from the oil, enhancing its drying properties and resulting in boiled linseed oil.
Uses of Boiled Linseed Oil
1. Wood Protection and Finishing
Applied to wood surfaces to provide protection, enhance finishing, and expedite curing.
2. Rust-Preventive Coating of Metal
Used on metal surfaces to prevent rust and corrosion, extending the lifespan of metal objects.
3. Coating of Industrial Products
Applied to industrial products for surface protection and durability improvement.
4. Artists’ Pigments
Incorporated into paints to enhance drying properties and improve finish and durability.
5. Furniture Finishing
Utilized in wood finishing for furniture to enhance aesthetics and durability.
Characteristics of Boiled Linseed Oil
1. High Drying Property
Boiled linseed oil dries rapidly, forming a protective film on surfaces.
2. Improved Durability
Provides durable protection against external elements, enhancing material longevity.
3. Shorter Drying Time
Dries faster compared to conventional oils, reducing overall drying time.
4. Diverse Applications
Widely used across various industries and art for its versatile properties.
5. Effective Sealing Effect
Forms a protective seal, preventing moisture and air penetration, thus delaying deterioration.
Types of Boiled Linseed Oil
1. Linseed Boiled Linseed Oil
Made from linseed oil, commonly used in wood finishing for its high linoleic acid content.
2. Soybean Oil Boiled Linseed Oil
Derived from soybean oil, frequently used for metal and wood protection.
3. Egoma Oil Boiled Linseed Oil
Produced from Egoma oil, suitable for wood finishing due to its alpha-linolenic acid content.
The type of boiled linseed oil varies based on the metal oxides added during production, influencing its properties.
