Gold lacquer, with its unique golden luster and elegant texture, is widely used in various artworks, furniture and architectural decorations. However, the surface characteristics of different materials pose different challenges to the adhesion and weather resistance of gold lacquer.

When gold lacquer is applied to metal surfaces, the adhesion and weather resistance of gold lacquer are often tested due to the conductivity and thermal expansion of the metal itself. In order to improve adhesion, it is usually necessary to pre-treat the metal surface, such as grinding, rust removal and cleaning, to ensure that gold lacquer can adhere tightly to the metal. In addition, there is the option of using specialized metal adhesion promoters, which can improve the wettability of the metal surface, allowing gold lacquer to better penetrate into the tiny pores on the metal surface to form a strong bond.

For materials such as wood and plastic, the adhesion and weather resistance of gold lacquer depend more on the hygroscopicity and chemical stability of the material itself. Wood surfaces usually require sealing treatment to prevent the penetration of moisture and stains, while increasing the surface roughness and improving the adhesion of gold lacquer. Plastic surfaces may require the use of special primers or treatment agents to improve their compatibility with gold lacquer.

In terms of adjusting the weather resistance of gold lacquer, the key lies in choosing the right resin and pigment. As the main film-forming substance of gold lacquer, the type and performance of resin directly affect the weather resistance of gold lacquer. Pigments determine the color and light resistance of gold lacquer. By carefully selecting resins and pigments, it can be ensured that gold lacquer can maintain bright luster and stable performance in different environments.

In addition, the construction environment and process of gold lacquer also have an important impact on adhesion and weather resistance. Construction under suitable temperature and humidity conditions, choosing the right spraying distance and spraying pressure, and controlling the thickness and drying time of the paint film are all key factors to ensure the adhesion and weather resistance of gold lacquer.

In summary, the application of gold lacquer on different material surfaces requires comprehensive consideration of material properties, pretreatment process, selection of resin and pigment, construction environment and process, etc., to ensure that gold lacquer can maintain its freshness and durability.
