Pigments
A pigment is a material that changes the colour of reflected or transmitted light as the result of wavelength-selective absorption. In other words, it’s a substance that appears a certain colour because it selectively absorbs certain wavelength of light.
The primary purpose to use pigments is to provide colour to materials, whether they are textiles or paints. Some people often consider pigments and dyes to be the same but they’re quite different. The major difference between the both is in terms of their solubility.
While a dye can dissolve by itself in a liquid, pigments can be dissolved in a liquid with the help of a binder. Dyes are primarily applied in the textile and paper industry, pigments are used in industries such as colouring paints, inks, cosmetics, and plastics.
Properties Of Pigmnets
Based on the method of their formulation, pigments can be categorized into two types: inorganic pigments and organic pigments.
- ORGANIC PIGMENTS:- This type of pigments occurs naturally and they’ve been used for centuries. They’re quite simple in their chemical structure. They’re named organic as they contain minerals and metals that give them their colour. Organic pigment manufacturers produce them through a simple process that’s made of washing, drying, powdering and combining into a formulation.
- INORGANIC PIGMENTS :-Inorganic pigment suppliers supply this type of pigments mainly to paints, plastics, synthetic fibres and ink industry. In uses where bright colours are required, organic pigments are used as they bolster high colour strength. Inorganic pigments include white opaque pigments which are commonly used to lighten other colours and also to provide opacity.
Benefits of Pigments
- Pigments application on cotton fabric in almost all segments right from protective coating paints to decorative coating paints.
- Pigments include emulsion paints, resin, and oil-based paints, aqueous based paints like lime etc., distempers, automotive finishes etc.
- Most pigments used in manufacturing and the visual arts are dry colorants, usually ground into a fine powder.
