A Brief Intro On Phthalo Blue Organic Pigments

The blue organic pigment range is dominated by one special chemical type that is known as Phthalocyanine. It is regarded as the ideal pigment. There are several fabricators who specialize themselves only in phthalocyanines. There are various other blue pigments, which include indanthrone which is used for particular fine quality applications, Ultramarine and Prussian blue which are two inorganic pigments seldom used. The printing ink industry makes use of certain cationic toners (ferrocyanide, alkali blue pigments and phospho tungsto molybdic acid) however their chemical resistance and poor solvent coupled with poor light fastness reveals that they have practically no use in the paint industry.

Examples of inorganic blue pigments are:

•          Ultramarine
•          Prussian blue
•          Cobalt blue

Examples of Phthalo Blue Organic Pigments are:

•          Indanthrone
•          Copper & Copper-free phthalocyanine

All these pigments must be carefully inspected prior making use in any industry, so that the products on which they are used must not show any adverse effect on it.

What And Why Of Flushed Color Dispersions

The flushed color dispersions are formulated by making use of a unique vehicle system that would meet the requirements of high gloss and high speed applications, consisting of catalogues, books and magazines. The fabrication of colored organic pigments entails wet state chemical processing. Post washing to get rid of detrimental soluble matter, the resultant press cake is pulverized, dried and usually blended for producing a dry powdered pigment. The drying and pulverization procedures of Flushed Color Dispersions could be the reason for causing agglomeration or aggregation of the pigment particles. Nonetheless, optimum performance is best achieved when the primary particle size of the pigment is maintained. The ink and paint maker, thus, has first to “wet” and then to break down the aggregated and agglomerated particles and alleviate the resultant dispersion by making use of high energy dispersing tool in combination with a resin or dispersing agent as suitable.

Water Paint Aqueous Dispersions: What Are They?

Natural Pigments introduces a new methodology of making conventional waterborne paint: water paint Aqueous Dispersions. Aqueous dispersions are pigments which are dispersed in water and are always ready to be mixed with water-based mediums. These dispersions are particularly made for use with customary painting mediums, like, casein, egg, watercolors, fresco and distemper, such as, glue tempera. They are also preferably suited for used with gesso for making toned grounds for painting and drawing.

Pigment dispersions contain only naturally-derived ingredients, in accumulation to water and pigment, making them idyllically suited for natural and traditional mediums. Contrasting to other pigment dispersions which are characteristically made for acrylic medium, aqueous dispersions does not consist of artificial dispersing resins, coalescent solvents and other additives which hinder with the natural mediums. Water Paint Aqueous Dispersions make preparing customary mediums easy; one does not have to hassle with powders, grinding pigments with costly tools and calculating pigment-binder ratios for making water-based paint.
