Internal mixing principle

The internal mixing principle is a fundamental concept in painting technology that is used when dosing and mixing paints and coating materials. In contrast to the external mixing principle, in which the components are mixed outside the spray gun, the internal mixing principle involves mixing inside the gun immediately before the material is applied to the surface to be painted.

With this technique, the individual components of the paint, such as basecoat and hardener, are kept separate from each other in special containers. Before they emerge through the nozzle of the spray gun, these components are mixed inside the gun. This is done by using a mixer or a mixing system that is integrated into the spray gun.

The advantage of the internal mixing principle is that the paint components are mixed immediately before application to the surface. This achieves a fast reaction time and minimizes the possibility of color deviations or undesirable reactions between the components.

This technique is widely used in various areas of painting technology, particularly in the automotive industry and industrial painting, where high precision and efficiency are required. By using the internal mixing principle, painters can achieve high-quality results and increase their productivity at the same time.
