Pearl Pigment Crystals pearlescent gold paint

Pearl Pigment is a glossy pigment. Non-toxic, tasteless, acid and alkali resistant, non-flammable, non-explosive, non-conductive, non-migratory, easy to disperse, with high heat resistance (900 degrees) and weather resistance, fully in line with strict environmental requirements.
1. How to use pearlescent powder safely
Pearlescent powder is a kind of translucent micro-flake pigments. Operators inadvertently inhaled into the lungs, will bring corresponding harm to the body. It is suggested that operators should wear masks and rubber gloves before mixing pearlescent powder, open the package and gently put the required amount into the tank (barrel), then soak in 30% ethyl acetate or isopropanol for 30 minutes. It is easy to operate, but it is not suitable to mix at high speed, otherwise the particle size of pearlescent powder will be destroyed and its gloss will be affected.
2. How to mix pearlescent powder with color
Gravure printing mainly uses low viscosity liquid ink. Pearlescent pigments should be prepared with high transparency binder (resin) and transparent diluent with good printing adaptability. When preparing color ink, different kinds of color ink should be selected according to different paper. White card and white board paper should choose pigments, and PET composite paper should choose dye pigments. Pigments and pearlescent powder can be mixed, generally not more than 20% of the pearlescent powder. If the tone is too heavy, the pearlescent effect will be affected, because pearlescent pigments can only have special light interference function in the light-rich ink layer, and excessive use of other colored pigments will cause a large number of pearlescent light loss.
Method of dispensing. Dilution agent: color ink: pearlescent ink = 75:3:22, can be added or reduced according to the desired effect of each proportion.
Operating method: First use diluent and color ink to mix (remember: to weigh to find the proportion), through scraping sample to mix slightly deeper than the required sample, then add soaked Pearl powder, evenly stirring, etc. Pearl powder in the ink after uniform dispersion can be used.
3. Rational Use of Pearlescent Powder on Composite Paper
For example, in the printing of pearlescent ink on PET composite paper, because of the better smoothness of the paper surface, the transfer rate of pearlescent ink decreases during the printing process, and the covering effect is also poor, and the print shows the color of the paper. Then in the process arrangement, we should take into account the free color sequence, printing pearlescent ink or base oil twice, so that the effect of pearlescent light will be more distinct; without the free color sequence, we should consider adding appropriate aluminium powder, white ink or transparent ink in pearlescent ink, so that the effect of pearlescent light will be slightly lost, but the covering rate will be improved.
