Red pigment violet 19 and blue pigment violet 19

In this huge and complex system in the field of chemical industry, the pigment purple 19 is undoubtedly a shining star, which belongs to the quinacridone organic pigments. In the chemical industry of many Pigment classification, each pigment has its own unique identification and identity information, pigment purple 19 is no exception, its index number is C.I.P.V.19, its Chinese name is Pigment Violet 19, and the English name is pigment Violet 19. From the microscopic level, its molecular formula is C20H12N2O2, a series of seemingly simple letters and numbers, but precisely define the molecular structure of the pigment violet 19, is an important reflection of its chemical properties.

According to the different production process, pigment violet 19 can be carefully divided into β type and γ type two. Among them, pigment violet 19 (beta type) is a purple pigment that presents an attractive red light. Among the color families of many pigments, it has a unique color light performance, and the color light of the pigment red 88 is very close. However, in terms of the two key properties of light resistance and weather resistance, pigment violet 19 (β type) has a better performance, which can easily meet the harsh requirements of long-term outdoor use. In the field of industrial coatings, which are widely used pigments, the use of pigment violet 19 (β type) has a unique stress. It is rarely used alone, and is more often mixed with inorganic pigments, such as iron oxide red, molybdenum chromium red and so on. This way of mixing is not random, but an effective combination proven by a lot of practice. When mixed with these inorganic pigments, it exhibits high hiding power, a property that is critical in industrial coating applications. Moreover, its light fastness is also higher than that of titanium dioxide when mixed with these inorganic pigments, which makes it irreplaceable in industrial paint application scenarios that require long-term exposure to sunlight.

Looking at plastic coloring, plastic as a ubiquitous material in modern industry and daily life, the demand for pigments is also extremely diverse. The transparent red violet in pigment violet 19 (beta type) plays an important role in this field. It can be used for the coloring of PVC (polyvinyl chloride) and PUR (polyurethane), both of which are widely used in building materials, household items, electronic equipment and many other fields. It is worth mentioning that in polyolefin, a common plastic, it can withstand high temperatures of up to 300 ° C, which makes its application prospects in the field of plastic products extremely broad. Whether it is an industrial plastic product in a high temperature environment, or a special purpose plastic product that requires heat resistance, the pigment violet 19 (β type) has the potential to be an ideal coloring choice.

In the pursuit of beauty and uniqueness in the field of metal decorative paint, pigment violet 19 (β type) also has a contribution that cannot be ignored. Metal products occupy an important position in people's lives and industrial production, from daily metal decorations to large industrial metal equipment, can not be separated from decorative paint to improve its appearance quality. When red violet is added to the metal decorative paint, it is like magic, which can give the metal surface a unique color and charming luster, instantly enhance the decorative effect of the entire metal products, so that it stands out among many ordinary metal products, and meet the needs of different users for the beauty and uniqueness of metal products.
