Which is the Largest manufacturer of phthalocyanine pigments?
When you’re thinking about colours, it can be hard to think of what shade of blue, red, or green you’re looking for. Thankfully, there are a variety of industries where colours are important, and they have to find the right colour pigments to use in their products. One of the most important colours that these companies need is phthalocyanine pigments, which can be used in plastics and cosmetics to get just the right colour you want to help your business succeed. Who is the largest manufacturer of phthalocyanine pigments? Read on to find out!
Phthalocyanine Colour Pigment Details
Phthalocyanine (also called phthalocyanine blue) belongs to a family of highly fluorescent, bright blue water-soluble pigment compounds. The colour ranges from greenish blue to bluish purple. The intensity depends on lightness and tone. Phthalocyanines are used as dyes in textile printing and as pigments in paints, such as automotive and architectural coatings; they are also present in cosmetics such as nail polish, hair dye, and shampoo.
How Phthalocyanine Colours are Made?
Largest manufacturer of phthalocyanine pigments to a class known as condensed aromatic hydrocarbons, in which multiple benzene rings are fused. Different manufacturers will use different methods to create such a colour, but most consist of heating and stirring pyridine with carbon disulfide over high heat. This produces C32H32N2S4, which is then treated with formaldehyde or anhydrous ammonia to form C16H12N2O8S8. Further manipulation turns it into crystallized plates containing different ratios of phthalocyanine and tetrasulfophthalocyanine. To make ink, manufacturers mix these crystallized plates with solvents and dispersants.
Standard Pigment Grades
Most Pigment Green 7 have different grades, or types, of products. Generally speaking, there are three types: water-dispersible, solvent-dispersible and solvent-soluble. As you might expect from their names, water-dispersible products mix well with water and oil-based systems; solvent dispersible formulations mix well with organic solvents, and solvent-soluble variants dissolve in organic solvents. Phthalocyanines have also been used to produce multiple colour states in a single paint formulation (eg. red/green/blue) allowing for more vibrant and durable coatings to be applied to metal substrates.
Technical Data about Phthalocyanines
Phthalocyanines are organic compounds containing copper, with the molecular formula CuPc or HOPc. They belong to a large family of molecules called metal-free dyes, which also includes diazonium and cyanine dyes. The name phthalocyanines refer to their blue-green colour; however, these molecules are rarely seen in nature as solids.
How Does Single Metal Phthalocyanine Compare to Double Metal Phthalocyanines?
Single metal Largest manufacturer of phthalocyanine pigments, or SMPs as they are sometimes referred to, have a different chemical makeup than double metal phthalocyanines. SMPs also exhibit higher melting points and better thermal stability, which means that they are more resistant to heat and air. Most colour manufacturers prefer these types of Pigment Green 7 Manufacturer for high-temperature applications because of their increased durability. This can make SMPs ideal for automotive coatings such as paints and clear coats. However, another one of their most important characteristics is that their colours don’t fade after long exposure to sunlight. This means they’re perfect for outdoor paints such as residential home exteriors that need strong protection from both UV rays and extreme temperatures.
Aluminium Phthalocyanines (APC) versus Zinc Phthalocyanines (ZPC)
Zinc Phthalocyanines (ZPC) are more efficient than Aluminum Phthalocyanines (APC) when it comes to heat stability. Whereas aluminium phthalocyanines begin to discolour at temperatures of 130°C, zinc phthalocyanines remain colourless even after they reach 180°C. This makes ZPC ideal for extrusion and pelletizing into sheet form and utilizing them in packages that will be used in extreme temperature environments.
