The recommended method of dispersion is to soak the granules in 1-2 times their weight of water for a maximum of eighteen hours, then mix gently to a creamy consistency, free of agglomerates by low shear stirring. When completely dispersed, the balance of the formulation may be slowly added under gentle but efficient agitation. To avoid damage to the pigment flakes that could induce gassing and reduce the metallic effect, agitation should be efficient but low shear. If it is necessary to use high shear to dissolve or disperse any component of the binder, this should be done before introducing the aluminium pigment. The final pH should be as close to neutral as possible. As the water stability of this grade is very system dependent, small – scale trials are recommended to verify the required level of performance.
