Product
D50 average of 10 microns) - creates a diffractive rainbow effect that appears to emanate from the surface in pleasing and subtle tones but with noticeably smoother, softer and more satin-like effects.
Standard grade pigment (D50 average of 20 microns) - optimally balances the diffractive rainbow effect with a high level of specular reflection.
Coarse grade pigment (D50 average of 35 microns, 50 microns) - produces a silver-based color with a diffractive rainbow effect that is more distinct and chromatic with a noticeably coarser and more sparkling appearance. | |

Remarks |
|
Choice of primer coat is important; the primer should give a very smooth finish with no surface defects for the basecoat to be applied to. The Rainbow paste will highlight any surface defects.
Dry film thickness of basecoat applied should be 2-5 micron.
Choice of topcoat is also important; the topcoat should be applied at the minimum thickness required for the necessary protection (typically 30 micron). Solubilisation of the basecoat from the topcoat solvents should also be avoided or minimised. If the solvents contained in the topcoat dissolve the basecoat resin, this will result in disorientation of the rainbow flakes and a duller finish. | |
