Which type of paint is commonly used on aircraft?

Synthetic enamels are commonly used on aircraft because they provide a durable, protective finish that can withstand various environmental conditions, including UV exposure, abrasion, and chemicals. These paints form a tough, hard surface that adheres well to metal and composite surfaces, which is critical in aviation applications where safety and longevity are paramount. Additionally, synthetic enamels can be formulated to achieve desirable aesthetic qualities, such as gloss and color retention, making them suitable for maintaining the exterior appearance of an aircraft over time.

While other options like polyester resin and epoxy paints are also used in specific applications within the aircraft maintenance and repair industry, synthetic enamels are favored for overall exterior surface painting due to their balance of performance, workability, and finish qualities. Latex paint, however, is typically not used for aircraft exteriors, as it lacks the durability and chemical resistance required for aviation standards.
