VMP is produced by stripping VMF pigment
vacuum metalized aluminum from polymer film using a solvent, such as ethyl acetate. This is followed by several
process steps that ultimately results in a10% -20% solids dispersion
Prior to metallization, the substrate film is coated with a “release coating” designed to dissolve rapidly in the stripping solvent
decreases, the appearance As flake thickness becomes darker and the overall reflectivity increases. The greater reflectivity of thinner flakes can be attributed to less light scattering from the flake edges. The scanning electron Image in Figure 3 illustrates typical flake

Agitators used for Aluminium dispersion
For normal dispersions from pastes, pellets, powders, the aim is to achieve good wetting of the pigment with the medium before dispersing the pigments.
Pellet: soak in solvent first to support carrier dissolution, start stirring at low speed, increase at the end, balance high speed stirring time to get an optimal dispersion.Powders: soak in solvent for good wetting of the pigment, start at slow speed and increase at the end, balance high speed stirring time Paste: start with low to moderate speed.
Jie han vmp have black shade to white shade , it is main use for ink , spray paint with mirror effect .
