How is gel coat typically applied in the composite manufacturing process?

The application of gel coat is most commonly done using an atomized spray gun. This method allows for an even and controlled application of the gel coat onto the surface of the mold. The atomization process creates a fine mist of gel coat that can easily adhere to intricate shapes and contours, ensuring a smooth and professional finish.

Spraying the gel coat is preferred in the composite manufacturing process because it allows for a quick and efficient covering of large areas, while also minimizing the likelihood of air bubbles and imperfections that can occur using other application methods. This is especially important in producing high-quality composite parts where aesthetics and surface integrity are critical.

Other methods, such as brushing or rolling, may not provide the same level of uniformity or finish quality. Dipping can also be impractical for many applications, especially in terms of waste and control over the thickness of the gel coat layer. Choosing an atomized spray gun reflects industry best practices to achieve optimal results in gel coat application.
