PU (Polyurethane) Coating

PU (Polyurethane) coating is a protective finish applied to various surfaces to enhance their durability, resistance, and appearance. Made from polyurethane polymers, this coating forms a smooth, flexible layer that protects against moisture, abrasion, chemicals, and UV exposure. It is commonly used on metal, wood, fabric, leather, and flooring to extend product life while offering a sleek, high-quality finish. PU coatings are available in matte, semi-gloss, and glossy finishes, making them a versatile choice for both functional and decorative applications.

PU Coating, short for Polyurethane Coating, is a protective finish that enhances the surface properties of various materials. It forms a thin, flexible, and durable layer that offers excellent resistance to scratches, moisture, chemicals, and UV rays. PU coatings are known for their strong adhesion, smooth texture, and ability to maintain their appearance even in harsh conditions, making them ideal for both indoor and outdoor applications.
This type of coating is widely used across multiple industries, including furniture, automotive, textiles, flooring, and electronics. It not only improves the functional durability of surfaces but also enhances their visual appeal with options in matte, semi-gloss, and high-gloss finishes. Whether applied to wood, metal, leather, or fabric, PU coating offers long-lasting protection along with a premium look and feel.

What is PU Coating?

PU Coating, or Polyurethane Coating, is a protective layer applied to surfaces to enhance durability, flexibility, and resistance against moisture, scratches, and chemicals. It forms a smooth, thin film that adds both strength and visual appeal to the surface.

PU Coating Process - How Does PU Coating Work?

The PU (Polyurethane) coating process involves applying a liquid or sprayable polyurethane solution to a surface, which then forms a protective film upon drying or curing. The surface is first cleaned and prepared to ensure proper adhesion. Once the coating is applied—either by spraying, brushing, or dipping—it spreads evenly and begins to harden through a chemical reaction or heat curing.
As it cures, the PU coating forms a thin, flexible, and durable layer that adheres tightly to the substrate. This coating acts as a shield, protecting the surface from moisture, scratches, UV rays, chemicals, and general wear and tear. Depending on the application, multiple coats may be applied for added thickness and enhanced performance.

PU Coating Finishes

PU (Polyurethane) coatings are available in a variety of finishes to suit both functional and aesthetic needs. Common finishes include matte, semi-gloss, and high-gloss, each offering a distinct look and level of shine. Matte finishes provide a soft, non-reflective surface ideal for subtle, elegant designs. Semi-gloss offers a balanced appearance with moderate sheen and durability, while high-gloss finishes deliver a sleek, polished look with maximum visual impact. These finishes not only enhance the appearance of the surface but also improve resistance to wear, scratches, and environmental factors.
