Pearlescent materials provide a broad field for paint process designers to create new colors and decorative effects due to their high refractive index, pearl effect, and viewing angle flash effect. Silver white pearl material endows the coating with a bright white pearl luster, and can also be used as a base coating to create decorative effects. Pearlescent materials can provide new and interesting colors and tones independently. This iridescent pearl material with light interference color can be used alone with resin to prepare clear pearl gloss paint, or mixed with conventional transparent paint to prepare pearl material color topcoat.
Precautions for Ink Printing Use:
Pre wetting of pearl pigments: Before mixing pearl pigments into ink, they should be wetted. The solvent used for wetting should be compatible with the ink system. Good wetting can evenly disperse pearl pigments into ink, which is the basis for obtaining high-quality pearl printing effects. Wetting can also overcome the "dust generation" phenomenon of dry powder during dispersion.
Dispersion of pigments in ink: Pearlescent pigments have good dispersibility and are generally stirred at low speeds in low viscosity inks. It is recommended to avoid using equipment such as three roll machines, high-speed mixers, or ball/bead mills as much as possible, as this can cause the pigments to break and lose their luster. It is recommended to mix the pigments in the final stage of ink production. When using a disperser or high-speed mixer, the mixing time for each batch should be kept constant and short.
Choosing ink media with good transparency: Whether it is ink pigments or binders, transparency is an important factor affecting the pearl luster of ink.
The distribution characteristics of pigments determine the effect: the more pearl pigments are distributed and the better the uniformity in the printing coating, the better the pearl effect will be; Another important point is that the ideal pearl effect can only be achieved when the pigment chips are arranged parallel to the surface of the substrate.、
