There are many varieties of organic pigment reds, with hues of yellowish red, normal red, blue red and dark red. Transparent red STA3 Product name: Transparent red BR (A standard) Product heat resistance: 200 degrees Product hue: Blue red Light resistance: Level 5 Weather resistance: Level 4 Acid resistance: 3-4 Alkali resistance: 3-4 resistance Migration: Level 3 Application range: Plastic hard rubber application dosage: 0.02% specification. Most organic pigment reds are azo red pigments. The traditional azo pigments have strong coloring power, and are not very good in heat resistance, light resistance and hiding power. They have strong pigment migration and are not suitable for powder coatings.
Some azo lake varieties can withstand a temperature of about 180掳C, such as: Pigment Red 48:1, 2, 3, 4, etc., the pigment is finer, the light resistance and dispersibility are not very good, the price is low, and it can be used for indoor powder coatings in. Transparent red STA3 Product name: Transparent red BR (A standard) Product heat resistance: 200 degrees Product hue: Blue red Light resistance: Level 5 Weather resistance: Level 4 Acid resistance: 3-4 Alkali resistance: 3-4 resistance Migration: Level 3 Application range: Plastic hard rubber application dosage: 0.02% specification. Pigment Red 48:1 is a bright yellowish red, Pigment Red 48:
2, 3, 4 are different degrees of blue shade of red, and the performance of pigment red 48:4 is better. Pigment Red 176 is blue-red in nature. It has bright shade and high tinting strength. The light resistance is level 6. The thermal stability is above 300鈩? The resistance to organic solvents reaches 4 to 5 grades without migration.
Most of the phenol AS have good resistance. The colors are yellowish red, normal red and blueish red, and have good light resistance. For example, the commonly used powder coatings are F5RK and F3RK with Pigment Red 170, the price is relatively relatively Moderate, can be used for outdoor powder coatings that do not require high light resistance. F5RK is a slightly darkened positive red shade, and F3RK is a yellowish red. Such as: Condensed azos, pyrrolopyrroles (DPP), anthraquinones, quinacridones and perylene reds and other high-performance organic pigment reds in the production of pigments, which have high temperature resistance. Excellent (explanation: excellent, very good) light resistance and weather resistance. After surface treatment, its dispersibility and hiding power are greatly improved than ordinary azo pigments, and the price is relatively high. It is suitable for outdoor powder coatings with higher requirements. .China Organic Pigments Red
