Liquid Coating

Liquid coating is the process of applying paint in liquid form onto the surface of an object through spraying, dipping, or rolling to form a protective or decorative layer. After the paint flows and spreads on the surface, it solidifies into a film through solvent evaporation or chemical reactions. It is used in fields such as metal corrosion protection, wood coloring, and plastic surface treatment.
Selection
Select appropriate paint types based on substrate characteristics, taking into account the weather resistance requirements of the usage environment. Determine the painting method according to the construction conditions: spraying is suitable for complex shapes, while dipping is ideal for small parts. Refer to coating thickness standards to choose the corresponding viscosity of paint, and ensure the drying method matches the on-site conditions.
