Solvent-based wood coatings are a type of surface treatment used to protect and enhance the appearance of wooden materials. These coatings are made by dissolving synthetic resins, pigments, and other additives in organic solvents such as toluene, xylene, butyl acetate, or cyclohexanone. Once applied, they form a durable and protective film that adheres well to the surface of the object.
These coatings are known for their high hardness, excellent wear resistance, strong corrosion resistance, and good low-temperature performance. They also have a moderate evaporation rate, making them suitable for various applications. Solvent-based wood coatings are widely used in construction and interior decoration due to their versatility and durability. Common types include polyurethane paint, nitrocellulose lacquer, alkyd resin, and phenolic coatings.
Polyurethane coatings, often referred to as "PU polyester lacquer" in the market, are particularly popular because of their toughness, strong adhesion, and heat resistance. They are the most commonly used in interior design and furniture finishing. Nitrocellulose lacquers, on the other hand, are favored for their ease of application, quick drying time, and simple repair process, making them ideal for use in furniture manufacturing. Today, polyurethane resin paints remain one of the most preferred choices for home decoration due to their balance of quality and cost-effectiveness.
