application performance organic pigments

Organic Pigments Industrial Technology Development and other industrial technology, its applications continues to expand, higher demands , prompting the related technology to the magnesium hydroxide flame retardant  deeper direction. Organic pigments its requirements can be summarized as follows: ① gentrification products that meet the metal coating durability, weather fastness , heat resistance, solvent resistance, and resistance to migration performance and other requirements ; ② organic pigments dosage of , the development of specific applications performance -specific products, such as water , oil , easy dispersibility , high transparency , heat resistance, excellent migration resistance new special formulations , having a high purity crystalline form of certain special features of the organic pigment.
  Applications department requirements to promote the rapid development of organic pigment industry technology , from classical organic synthesis reaction unit ( such as halogenation, nitration , reduction, condensation, diazotization, coupling reaction ) , filtration, separation, drying, grinding process gradually penetrate multidisciplinary areas  iron oxide black such as solid state physics chemistry, morphology, powder surface chemistry, interfacial chemistry , solid solution and crystal chemistry , polymer chemistry and powder dispersion technology. Which highlights the research focus for the development of new varieties of structural pigments , colored crystal particle surface modification treatment technology, efficient pigment dispersion technology , organic pigments and commercial processing technology and application performance testing and evaluation. ( A ) the chemical structure of the pigment new breed was developed to improve the durability of paint , heat stability, resistance to weather fastness , solvent stability and resistance to migration performance ; bright shade , high tinting strength yellow, orange , red, purple and brown varieties to meet with performance dacron blue, green, copper phthalocyanine pigment to match the requirements. The principal means of synthesis of new heterocyclic structure of the pigment , a good Acrylic processing aid  molecular planarity . Symmetry , with a specific substituent , change the molecular polarity , can form intermolecular hydrogen bonds , to improve heat stability and resistance to migration . Based paint durability ( light resistance, weather fastness , heat stability , solvent resistance and migration resistance , etc. ) of the level classification , grade ( high ) , or organic pigments HOP HGP (HighPerformanceOrganicPigments; HighGradePignents), has not only excellent application fastness properties , and value-added products , is high. Undoubtedly increasing organic pigment product formulations to meet specific application areas , high-performance requirements, will be an important trend in the future .
