Powder Coating, Marking powder, Paints and Cotton textile

POWDER COATING:
Ultramarine Blue has some Techno-Pigmentary properties that make them specially indicated and recommended to be used in powder coating either for blue tinting or as whitening additive.

Ultramarines are selective pigments for powder coatings in all the range of blue shades, dark or pastel, with their characteristics shade purity.

Ultramarine Blue has a specific application in white powder coating as neutralizer of the yellow shades of some resins, The elimination of yellow gives best result in the whiteners degree, that can be measured and highlights, and enhances the visual assessment of white.

The basic - physico - chemical properties of the ultramarine pigments are well known, that have cemented their use and consolidation in industries of all types of plastics, paints and inks. The following list details the main characteristics of the Ultramarine Blue, ideal for the accomplishment of the requirements to the pigments in the powder coating sector:
  Fineness 
  Dispersibility 
  Atoxicity 
  Temperature resistance 
  Light resistance 
  Weather ability 
  Solvents resistance 
  Chemical Resistance 
  Absence of impurities, that may disturb the process. 
  Minimum incidence on mechanical properties. 
  Easy handling

MARKING POWDER:
Marketing powders are mixtures of Calcium Carbonate 15% Ultramarine Blue. They can be used to mark lines or sketches in carpentry, metallurgy, masonry, etc. and for the painter, to mark lines or separations between colours, when painting a wall. The product is supplied in powder and it has to be sprinkled, directly from the flask, on what you want to mark or by impregnating a rope in the powder, wetting it lightly.

PAINTS:
The Ultramarine Blue has wide use in paints because it is not limited to any specific type of paints, given its excellent properties. To make opaque paints about 5% of Titarium dioxide must be added to the paint formula, by this way we get the characteristic and distinctive blue-reddish shade of the Ultramarine. Ultramarine can be used in all types of paint as correctors of white, yielding a paint which gives a whiter appearance. In this way it is used in the adjusting of any decorative white paint, air dried and oven baked alkyds, in plastic paints, etc. Because of its excellent light fastness, it is highly recommended for painting machinery, trucks and buses, motor cycles etc. If the paint is exposed to acidic atmospheres, precautions must be taken, like the application of a topcoat over the coloured undercoat. It not, frequent repainting will be needed. Nevertheless, it is not exceptional to use the Ultramarine Blue in unfavourable conditions. In these cases the shade purity of the pigment is used for publicity aims, and the colour obtained explains why it is preferred in unfavourable conditions.

In oven dried paints Ultramarines are very satisfactory for their good dispersion as well as their thermal stability. The pH of melamine formaldehyde resins tends to be acidic but Ultramarine Blue offer sufficient resistance. Paints for Joys, in which alkali resistance and the absence of toxicity are important, is another good area forthe use if Ultramarine Blues.

Nitrocellulose lacquers for painting pencils must have not toxic components and the Ultramarine Blues are very appreciated because they are non-toxic, give good gloss, easy dispersion and good rheology. 

Polyurethane paints can be coloured with Ultramarine Blue, being specially appreciated for its good gloss retraction and the characteristic blue shade, difficult to be equaled by other pigments.

Any grade of Ultramarine Blue can be used in paints but to obtain dark blue shades are recommended the grades with the highest tinting strength.

As an additive for whiting, dark and medium shades are preferred as they give excellent results in water paints as well as oleoresin enamels.

Therefore it has wide uses in paints, because it is not limited to any specific type of paints, given its excellent properties.

COTTON TEXTILE:
Ultramarine Blue is widely used at the time of washing of clothes. White clothes has a natural tendency of becoming yellowish. When it is washed with Ultramarine Blue (Laundry Grade) it absorbs the yellow light and gives a bright white look to the clothes. It is widely used in Hosiery Textile after bleaching of the fibre.

Peacock Pigments Private Limited is manufacturing very high quality Ultramarine Blue both Technical and Laundry Grade and meeting the specific requirement of the industry. Very rigid quality control is maintained at the time of manufacturing, satisfying all the International Standards.
