A distributor of pigment ink and worked to solve the problem of limited duration of the ink. Currently in gold dust and silver is screen printing inks have been developed with the metallic components. The shorter shelf life is six months. Since the aluminum may react with water or moisture and hydrogen evolution which can cause an explosion. After oxidation, the color is white and silver gray. It is because the metallic pigment is a mixture of long-term with a compound of transparent material. The chemical reaction and emulsification is performed. After printing, make it smaller open areas, the color of the printing ink or color vision less.
The chemical properties of the pigments of gold and silver can not be sold directly to the finished product silicon powder can be added. Ink gold, the metal powder of silver is used, some copper and aluminum, the role of water, air, heat, certain chemicals lost oxidize metallic luster. Appear in the gold ink, the pigment is made of copper, zinc, consisting of a mixture in different ratios. Gold and silver laminate resin of clarity of reflection of light is larger, the better the shine of the printing ink.
The particle size of pigment is too late to sacrifice some "is the brightness, despite this, the greater the benefit that the surface of the cage in a reasonable relationship with good coverage (the same weight of fine pigment may be extended to larger area .) The pearlescent pigment of pearl color (or aluminum) on the binding material in a transparent or colored ink. silver can be used polished coats of paint, a light color but not as good as the extension of the silver ink in various levels. Note also that the powder was treated with extreme as the premise of silver paint.
In silver paint mixed with aluminum pigment powder should be very careful. Oxidation is one of the reasons inaccessible powder of gold and silver texture color ink. Typically used in painting, the lower the better. Therefore, using the amount of pigment may be included with the premise to obtain a white color and the surface of the cage. The loss of strength and wear on the ink layer of metal over the layer of ink and then printed painted.
The metal oxide powder is easily leads in powder pigments, for example, oxidation of the copper, zinc particles with a consequent reduction of the brightness of the ink in some cases, the ink is also a light green color. Syrup starts to improve the brightness of the ink, dibutyl be used for the ink flow, the function has increased for drying ink, such as dibutyl phthalate oil Mexican oil having a leverage, by adding dry, so fast drying ink . Display silver blue ink, for example, a blue light. Dried ink film ink color pre-printed is yellow or green and gold will change.
Recent advances are among the types of effects of the impact of new metallic colors, chrome look. No color layers of gold and silver has a wide range of silver nickel powder. The challenge of the ink is a little red pigments, orange and yellow pigment can be damaged by the metal to react with the printed image. Like all other products, comprises one screen printing ink composition of powder of gold and silver in the production process and the functional limitations. The strength of the ink can be as much as possible to present to the client. Therefore, it is a golden opportunity for ink printers. Source:http://www.mhcmp.com

The global market share of metal powder coatings is expanding. The global powder coatings market reached $ 3.94 billion in 1999. It is $ 5.88 billion in 2005. Powder coatings remain strong in growth. The Asia-Pacific region and Latin America has largest increase. Nevertheless, the market share of North America and European powder coatings in coatings industry is less than 15 percent, while Asia and Latin America is far behind the data.
