To make the QC application card to test the color shade, whiteness and luster stabilities. The details formation in the below
Resin we used in drawdown:
Polyurethane resin : N,N-Dimethylformamide : butanone = 7 : 1.8 : 1.2
A. Particle size range of pearls ≤100μm, Powder: ethyl alcohol: Resin=0.2g:0.3g:1.8g mixture, drawdown on the film, thickness=200μm
B. Particle size range of pearls >100μm, Powder: ethyl alcohol: Resin=0.1g:0.15g:1.9g mixture, drawdown on the film, thickness=200μm
Evaluate color in standard light D60 source.
