Pigments inorganiques
Revêtements poudre:Peinture poudreIndex. décimale : 667.2 Colorants et pigments Résumé : The authors discusses the dispersion of Complex Inorganic Colour Pigments (CICPs) in powder coatings.
The previous article discussed the general properties of the class of high-performance pigments known as Complex Inorganic Colour Pigments (CICPs). These pigments are known for their outstanding inertness and resistance to chemicals, migration and weathering. They also have some inherent colouring properties advantageous for powder coatings. The control of colour in powder coatings depends on the predictability of the dispersion of the coloured pigments. CICPs have dispersion properties that produce colour that is controllable and stable. CICPs give controllable colour because the relatively higher use-rates as compared to organic pigments allow more advantageous mixing ratios. This can be demonstrated in the tinting of near white colours. Stability is beneficial if the powder coating needs to be re-extruded to correct for other colourants performance. The CICPs will not develop as much colour as standard organic pigments. Stability can be demonstrated by comparing a light blue tint colour made with either standard phthalo blue (PBI15.1), or Cobalt Blue (PBI28).Note de contenu : - Explanation of testing procedure

PigmentsIndex. décimale : 667.2 Colorants et pigments Résumé : Holiday Pigments has developed an ultramarine blue to satisfy plastic bottle processing requirements.
One of the most ancient and revered of pigments, ultramarine blue has a distinctive and irreproducible colour. Already used extensively in food packaging, new grades have been developed to meet the tough demands of new plastics moulding techniques including, mineral water bottles, passing strict organoleptic tasting tests.
The Ancient Greeks regarded blue as the ultimate colour of perfect peace and purity, sacred to them as the blue of calm seas in mid-summer - halcyon days. They revered the kingfisher ; the brillant flash of blue from the European kingfisher's wing reminds us of this and the genus of kingfishers is also named Halcyon.
The rare mineral lapis lazuli was the original ingredient for this blue heritage and created the colour adored by artists from Egyptian pharaohs, through classical antiquity and the Renaissance to the present day. Until the 19th century, the only process to extract the pigment was expensive and complicated. In 1828, the first economically viable, synthetic version of ultramarine blue to reproducce lapis lazuli was discovered by Jean-Baptiste Guimet and started the modern industrial process.Note de contenu : - Development of principles

Rayonnement infrarouge
Réflectivité thermiqueIndex. décimale : 667.2 Colorants et pigments Résumé : In tropical countries, during the hot summer days, as the surrounding temperature rises the solar heat absorbed by the walls of buildings is conducted into the interiors making them uncomfortable to live. Ordinary paints, apart from whites, do not have the capacity to protect the substrate from heat accumulation and consequent conduction. However a new generation coating system formulated with Complex Inorganic Colour Pigments (CICP) actually cut-off this heat. They are infrared reflecting pigments and can reflect IR radiation incident on them to a great extent. Room temperature of buildings whose exteriors are coated with these paints is found to be lower by 40-60. This saves energy (in form of air-conditioner bills). The foregoing paper discussed in brief the principle of heat reflection by these CICPs, their usage and method of evaluating the same. Note de contenu : - Infrared reflecting coatings

Pigments organiquesIndex. décimale : 667.2 Colorants et pigments Résumé : Copper phthalocyanine pigment (CuPC) is one of the most stable pigments towards light, temperature and chemicals. It exists in different crystal modifications. Crystal modifications α, and β have gained considerable commercial importance in industry . Crystal modification "α" is called pigment blue 15.0. It is obtained by acid pasting of crude CuPC. Pigment blue 15.0 is only stable upto 170°C. It shows very poor solvent resistant and also limited temperature stability. PB15.1 is improved version of PB15.0 with higher thermal stability but poor solvent stability. High thermal stability is achieved by surface modification of PB15.0 with suitable additive. Because high thermal stability it is used in all types of plastics and rubbers. PB15.2 is improved version of 15.1 with high solvent and thermal stability. All grades of pigment alpha blue are manufactured by process called acid pasting. Pigment alpha blue is used in various applications such as plastics, rubbers, ceramics, cements, inks, paints and cosmetics. Due to its high thermal stability, it is used in high performance coatings and engineering plastics. Note de contenu : - Manufacturing process of pigment "a" blue
