The aluminium pigment present in paint is primarily responsible for colour and hiding power but it plays an important role for the physical properties of the film. In anti-corrosion primers the aluminium have inhibitive or rust preventing properties. In top paints, the aluminium are flake-like particles in order to increase the oxygen diffusion path.
