What Do You Need To Know About Pigments?
Pigments are the color of any object. This article will teach you some interesting facts about pigments. Pigments are used in a variety of ways such as painting or coloring.
History Of Pigments
Colors are an essential part of our lives. It provides aesthetic satisfaction in almost every aspect of our lives, including clothing and food. Colors help us represent our true selves, and pigments were the perfect accidental discovery humans needed. Traditionally, men used organic pigments to paint and draw on caves, such as yellow earth, white earth, and chalk. Egyptians first produced pigments on a large scale. The pigment green 7 is a solid material that is not soluble in water and, when added to any medium, improves or brightens its appearance. Since they cannot dissolve in water, they are added to the medium by crushing them into a fine powder.
Types Of Pigments
Organic and inorganic are the two types of pigment available in the market.
Inorganic Pigment
The inorganic pigment is made of dry ground minerals. They do not consist of carbon chains or rings. Since inorganic pigments consist of metals and metallic salts, they are more non-transparent and insoluble. The inorganic pigment is preferred over organic pigment owing to its economical cost and fast-moving nature.
Organic Pigment
Organic pigments are made of carbon chains and rings. The composition of carbon chains and rings makes organic pigment very stable. Organic pigment is generally procured from animals, vegetables, or synthetic organic chemistry. Previously, these types of pigment were derived from flora and fauna. However, modern organic pigments are procured through synthetic organic chemistry. Synthetic organic pigments are made from aromatic hydrocarbons. Aromatic hydrocarbons include coal tars and various other petrochemicals.
Some Interesting Facts About Pigments
Heat, Light, And Air Resistance
Even when subjected to bright light, inorganic pigment does not lose color. Inorganic pigment retains its color and does not fade away quickly. Inorganic pigments also resist fading even when exposed to open air and high heat. Therefore when the inorganic pigment is used to manufacture other products, they preserve their color and aesthetic satisfaction for an extended period. But organic pigment is not much resistant to heat, light, and air. They tend to lose their color quickly and become dull and vanish.
Cost-Effectiveness
When inorganic pigment is produced in large quantities for industrial purposes, they are less costly and economical. The cost of production remains at a very nominal level. Simple chemical reactions are employed in producing inorganic pigment. Thus, it is very cost-effective. But organic pigment is produced by employing complicated chemical processes. They are expensive, primarily synthetic organic pigment. Organic pigments, thus, are less economical and are preferred less for industrial purposes.
Stability
Organic pigment is very stable owing to its composition of carbon chains and rings. However, they break down quickly when they contact with organic solvents and heat. But this is not the case with inorganic pigment. The inorganic pigment remains stable even when subjected to heat or mixed inorganic solvents. Thus inorganic pigment is a more dependable option for industrial purposes.
Source Of Primary Raw Material In Various Industries
Pigment Green 7, the most commonly used pigment, is the primary raw material source in various industries such as ink, paint, plastics, etc. Dhanveen pigment is India’s one of the most prominent phthalocyanine pigment green 7 manufacturers This pigment is so lightweight that one can be easily transported from one place to another. Owing to its lightweight, when used to manufacture other products, it does not add any additional weight to the product. It is resistant to rust and is extensively used in metal industries. It is a chief material used in metal industries to protect it from rusting and thus maintain metals' beauty for a long time. The bright and shiny appearance of pigment green 7 helps to make products very aesthetically pleasing. Dhanveen pigment, a pigment green 7 manufacturer, helps you to make your products retain their color and appearance for many years.
Size Of The Particles
Organic pigment and inorganic pigment have different sizes of particles. The inorganic pigment has large-sized particles, whereas organic pigment has slightly smaller-sized particles. Large-sized particles of inorganic pigment help it to scatter light more efficiently. When lights scatter effectively, it blocks the passage of the particles through the substance, thus making it more opaque. Due to this very reason, organic pigment is considered colorless, whereas inorganic pigment is considered opaque.
Dispersion Area
Inorganic pigment disperses more than organic pigment. Since inorganic pigment disperses more, it is more convenient to use in large-scale production for industrial purposes. Due to its economical cost of production and easy manufacturing process, inorganic pigment is a more commonly and frequently used pigment.
.Some Examples Of Inorganic Pigment
Since the inorganic pigment is more commonly used for industrial purposes, here is the list of some standard inorganic pigment that is used in large scale manufacturing processes – Titanium dioxide, black pigment, chromium pigment, cadmium pigment, white extender pigment, iron-oxide earth pigment, metallic pigment, and iron blue.
Some Examples Of Organic Pigment
Organic pigment is costly and has a complicated manufacturing process. Here is the standard synthetic organic pigments list – alizarin, copper phthalocyanines, azo pigments, and quinacridone.
Which One To Choose: Organic Or Inorganic?
You need to consider several things when deciding between organic and inorganic pigment. If the product to be manufactured has to stay in sunlight for an extended period, the inorganic pigment should be used since they are more resistant to light and heat. However, if your main priority is to make the product appear shiny and bright, the organic pigment should be preferred.
Cost is also one of the most important factors when deciding between organic and inorganic pigment. The inorganic pigment is cost-effective and is more economical when used in large-scale production. Also, owing to its light-weightedness, one can easily carry it from one place to Organic and inorganic pigment has its own merits and demerits. It depends on the type of industry to choose between them.
