Pigments

Phthalocyanine (PC) pigments constitute a broad class of pigments. PC Blue and PC green are among the most important organic pigments.

Copper phthalocyanine blue is the copper (II) complex of tetra aza tetra benzoporphine (CPC) whereas Phthalocyanine green is its chlorinated derivative (Pigment green 7). The brominated derivative of CPC provide a yellowish green shade(Pigment green 36).

The specific crystal modification decide the hue of the product as in Alpha blue - red shade copper Phthalocyanine (Pigment Blue 15) and in Beta blue - green shade blue (Pigment Blue 15:3). The Alpha modification which is phase stabilised by partial chlorination called solvent stable alpha blue or Pigment Blue15:1.

The Alpha modification which is stabilised towards flocculation and the phase change are registered as Pigment Blue 15:2. These pigments find use in paints.

The details of the individual class of pigments together with its application is given separately.

The Mixed metal oxide pigments gives high performance when it comes to their application as colorants. The generic name that is given to the class of pigments called mixed metal oxide pigments best describes the cobalt based pigments.

Constant researches has led to the development of new cobalt blue and blue-green pigments. They are often termed as the second generation pigments. Features like enhanced UV absorption and durability. Pigments like Cobalt chrome aluminate blue-green pigments show very good absorption rates. They transmit even less than 0.1% light in the Ultra violet region. These mixed metal oxide pigments (second generation pigments) owe their excellent absorptive properties to a fine particle size distribution. This excellent property is shown in the form of a graph.

Striking Features :

• Very good compatibility with most of the resin systems.
• Excellent thermal and chemical stability.
• Ability to withstand high temperatures. As these pigments get produced as a result of solid-state reaction of salts or metal oxides at high temperatures. They show the unique ability to undergo extreme temperatures encountered during phases of processing or application.
• Increased Tinctorial strength.
• Competitive pricing.
• Application of these pigments along with organics displays improved light-fastness property compared.
• Mixed metal oxide pigments assumes the role of UV opacifiers, that can efficiently scatter away UV and visible light from the coating's surface.
• Application of Mixed Metal Oxide Pigments
• Mixed metal oxide pigments have a diverse range of applications.
• To color vinyl siding
• Window profiles
• Garden tools
• Automotive components
• Appliance housings
