Application of wood lacquer anti-oil agent
Wood lacquer anti-oil agent is an additive used to improve the performance of wood coatings. Its core function is to
enhance the anti-oil ability and surface smoothness of the coating film, thereby extending the service life of wood products
and improving the convenience of cleaning. The following is an explanation from the application principle, usage scenario and
technical points:
1. Application principle
Wood lacquer anti-oil agent reduces the surface tension of the coating, making it difficult for oil stains to adhere, while promoting
the leveling of the coating film and reducing defects such as shrinkage holes and pinholes. Its chemical composition is usually
modified polysiloxane or high molecular weight polymer, which has high temperature resistance, oxidation resistance, aging
resistance and other characteristics, and is compatible with a variety of wood coating systems (such as PU, alkyd, acrylic acid, etc.).
2. Typical application scenarios
Furniture and cabinets
In environments that are prone to oil stains such as kitchens and restaurants, wood lacquer anti-oil agent can significantly improve
the anti-fouling property of furniture surfaces. For example, after using anti-oil agent on dining tables, cabinet door panels and other
parts, oil stains are easier to clean, reducing the problem of stickiness or discoloration after long-term use.
Floors and walls
Wooden floors, wood-veneered walls and other areas need to resist footprints and stains for a long time. Oil repellent can enhance the
wear resistance and permeability resistance of the coating and delay aging.
Outdoor wooden products
Outdoor wooden planks, wooden fences, etc. need to resist rain and grease pollution. Oil repellent can be used in conjunction with
waterproofing agents to form a double protective barrier.
3. Technical points
Addition amount control
The recommended addition amount is 0.05%-0.3% of the total amount of paint. Excessive addition may cause the coating to become sticky
or affect adhesion. The optimal amount needs to be determined through a small test.
Compatibility test
Before use, the compatibility of oil repellent and wood coating needs to be verified to avoid problems such as stratification and gelation.
Construction environment
The construction temperature should be controlled at 7°C-25°C to avoid frost or high temperature environment to ensure that the oil
repellent can fully play its role.
Coating thickness
Oil repellent is usually used in conjunction with primer and topcoat. It is necessary to ensure that each layer of coating is completely dry
before proceeding to the next process.
4. Advantages and precautions
Advantages: Improve the oil resistance and durability of wood surfaces, reduce cleaning and maintenance costs, and improve the
appearance of the coating (such as gloss and smoothness).
Precautions: Avoid contact with strong oxidants and strong acid and alkali substances; seal, moisture-proof and sun-proof during
storage to prevent failure.
5. Typical product characteristics
Ingredients: modified polysiloxane copolymer, polyester-modified dimethyl polysiloxane, etc.
Performance: Temperature resistance up to 250°C, with multiple functions such as anti-sticking, lubrication, and anti-oxidation.
Application system: Suitable for water-based, solvent-based wood coatings and ink systems.
Wood lacquer oil repellent provides a more efficient protection solution for wood products by optimizing the coating performance,
especially in easily polluted environments, which can significantly improve the product value.
