Though satisfactory results may be obtained by careful addition of AQUAVEX NL 015 to the liquid vehicle, the recommended method of incorporation is to briefly soak the product in 1-2 times its own weight of water. Dispersion is achieved by low energy stirring, using a slow speed blade capable of moving the whole mass. This premix is then slowly added to the agitated bulk of the water-based binder system.

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 premix. 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.
