Violeta pigmento 23-Corimax Violet RLS

Pigment violet 23 is an organic compound that is a commercial pigment. It is member of the dioxazine family of heterocyclic compounds, but derived from carbazoles. It is prepared by condensation of chloranil and 3-amino-N-ethylcarbazole. It has a centrosymmetric angular structure. For many years, the structure was assigned, incorrectly, as having a "linear structure" (EC no. 228-767-9, CAS RN 6358-30-1) which differ in terms of the carbazole ring fusion.

Pigment violet 23 is prepared by condensation of an aniline with chloranil.[From Wiki]

low viscosity, high gloss, high color strength. Pigment Violet 23 is a transparent purple violet pigment with high saturation and tinting strength.

C.I.Pigment Violet 23 show good tinting strength in flexible PVC while poor resistance to immigration.

P.V.23 heat resistance above 230℃ in polyolefins, when used in transparent PS, temperature shall below 220℃, above this PV 23 shall decompose. When worked in polyester, it is 280℃ stable in 5 hours, while concentration shall above 0.05%.

The pigment is easy to use and requires no rinsing. To ensure maximum color intensity and proper adhesion to the pulp, a retention agent must be added to the pulp before the pigment is applied. Our pigments are supplied by volume sizes. The actual weight varies, depending upon the density of the pigment.

Aplicação:

Recomendado para tintas automotivas, revestimentos arquitetônicos, revestimentos de bobina, tintas industriais, revestimentos em pó, pastas para impressão, PVC, borracha, PS, PP, PE, PU, tintas offset, tintas à base de água, tintas à base de água, tintas à base de solvente, tintas UV.

Pigment Violet 23 (PV 23) has now been around for more than 55 years. Its beginnings go back to 1928, when a patent was filed for the pigment after researchers at the Hoechst company in Germany first undertook the multistage synthesis based on carbazole, an ingredient of coaltar, and chloranile. Until the end of World War II the pigment was only used to process diamine light blue, a direct dyestuff for cotton.

With the invention of reactive dyes, which considerably simplified the dyeing and printing process for cellulose fibers, this application lost its importance. A new and promising use for PV 23 was quickly found due to the pigment’s ability to produce unique colors.

PV 23 has been used as a pigment since 1953. PV 23 belongs to the group of high-performance polycyclic pigments (HPP’s) that are used whenever the requirements for a colorant are particularly high. These include high light fastness and weather fastness, fastness to solvents, and heat stability. In addition, PV 23 stands out by its high coloring power. Under the electron microscope, the crude violet shows a highly granular crystalline form, whereas the pigment particles are miniscule.
