Pigment Red Improves The Anti-emulsifying Properties Of The Ink

May 31, 2017

Pigment red for the calcium salt lake organic pigments, organic pigments occupy a very important position, both the yield or the amount is very large, the variety is suitable for a variety of ink, shade in line with three or four color printing products Red standards, Pigment Red and also meet the relevant EU standards (such as aromatic amines and heavy metal content).

Pigment red in the ink has a good light fastness 4-5 (1/1 SD), high color strength, the preparation of 1/1 of the standard color depth, offset ink and lead ink only 18-20% of the pigment. The addition of certain second components during the synthesis process can change the color, Pigment Red particle size and distribution, and also improve the anti-emulsifying properties of the ink. In the ink pigment red resistance commonly used solvents, but poor acid and alkali resistance, sensitive to the varnish coating.

In the plastics industry, can be used for masterbatch and soft PVC, mainly used for light fastness requirements of the place is not high, due to poor lightfast performance, but also limits its coating, especially latex paint applications , But the pigment red as a classic pigment, Pigment Red in the market application still plays a very important role.

Pigment red: blue light red, good light fastness and solvent resistance. Europe for ink, the United States and Japan for paint. (1 / 25SD), while the pigment red 146 for the 5, 4; and molybdenum chromium (Figure), the color is bright, light 6-7 (SD), 5 (1 / 25SD) Red color, giving non-transparent red, large particle size in Japan for automotive coatings and CI paint red 170 competition; can be used for hard PVC and viscose fiber pulp coloring and cosmetics (lip red, eye shadow and nails Oil, etc.). Mainly used for ink, paint, paint printing paste and plastic latex and paper coloring.

Pigment Red is a lead containing lead molybdate and lead chromate, lead sulfate inorganic pigments, can have orange to red variety of varieties. Its color is clear, the color is higher than the orange chrome yellow, hiding power and a variety of major resistance indicators are very good. Molybdenum red red in the paint to be widely used, such as can be made of orange paint. Can also be used with the white anti-rust paint made of similar reddish appearance of molybdenum chromium red anti-rust paint. Molybdenum chromium red is also often with the sun will be able to good organic pigment fight color, can be resistant to solvent, not gold, Pigment Red resistant to baking temperature of the big red baking paint. For plastic coloring, molybdenum chromium red is also often the same heat resistance of organic pigments dubbed bright heat red, with the carbon can be dubbed brown. In the use of ink, molybdenum chromium red chrome yellow is similar to the performance of an orange pigment. Molybdenum chromium red in the practical application of a variety of shortcomings such as lead and cadmium, such as the crystal is easy to change, so that the color to change, light resistance and weather resistance is not very satisfactory, in 1944 began to aluminum hydroxide, titanium , Cerium and other oxides for surface treatment.
