Pritty pearlescent pigments can be incorporated in all coating systems. Pearl pigments are widely used in Automotive OEM, Car refinish Paint, architecture and decorative paint, Coil and powder coating.
Tips for the best results with Pritty pearl pigments in the paint industry:
1. Dosage/loading
Pearl pigment dosage is determined by many factors, such as its coating thickness, the method it’s applied, its transparency, and the surface area to be covered and the final pearl effect. In general, a sufficient dosage is 5 - 10% in weight. Sometim
Tips for the best results with Pritty pearl pigments in the paint industry:
1. Dosage/loading
Pearl pigment dosage is determined by many factors, such as its coating thickness, the method it’s applied, its transparency, and the surface area to be covered and the final pearl effect. In general, a sufficient dosage is 5 - 10% in weight. Sometimes, a weight of just 1% can produce a beautiful transparent and sparking effect. For thin coatings, the dosage should be increased to around 20 - 30%. Be warned, too many pearl pigments doesn’t guarantee that the platelet-shaped effect pigments will be aligned evenly to the surface and will have their full optical effect.
2. Pre-wetting, dispersion and stirring
Pre-wetting the pearl pigments with solvent or binder components usually makes it easier for dispersion and the best way is to make it into slurry to avoid foam coming out while stirring. To keep a consistent colour shade and avoid flocculating, optimal length of time for pre-wetting is 24 hours.Pearl pigments are easy to disperse and normal stirring is sufficient, so never use high shear machines, which will destroy the pearl pigment platelets and reduce or totally lose the pearl effect.
3. Methods to improve hiding power of pearl pigments:
Note: Non-transparent or dye will reduce the pearl effect.
