Introduction:
Various industrial and personal requirements involve the use of differentiation of products. It is for this purpose that solvent dyes may be used. Sometimes, the application of dye may be just the right solution to provide for an exquisite appearance of the product. Every type of solvent dye has its own features. Read further to find more about the applications and the features of the different kinds of solvent dyes present in the market. Before that, you must know what a Solvent Dye exactly is.
What is a Solvent Dye?
A solvent dye is used in dye soluble organic solvents. There are several types of solvent dyes including:
• Solvent yellow 21
• Solvent yellow 82
• Solvent red 8
• Solvent blue 48
• Solvent red 122
• Solvent black 27
• Solvent black 29
• Solvent orange 62
• Solvent violet 8
and more.
Characteristics of the solvent dyes
As the dyes are lipophilic, they are soluble in organic solvents and do not dissolve in water. Though majorly lipophilic, the molecules of the solvent dye are more or less non-polar and sometimes it may be polar. The dyes do not undergo ionization and they do form a colloidal solution. Solvent dyes may have a poor, medium or good light-fastness property.
Red dye and yellow solvent dyes are known as azo dyes while the blue and the green ones are known as anthraquinone dyes. The dyes do not give rise to discrete residues or films during manufacture. The solvent dyes have granular redisposition. Most of the solvent dyes are soluble in solvents including alcohols, waxes, oils fats, aromatic hydrocarbons.
Uses and applications of the solvent dyes
Solvent dyes are used for colouring and thereby identification of organic solvents like lubricant plastics, waxes, hydrocarbon fuels and other kids of hydrocarbon-based carbon fuels. The solvent dyes are also used for gold imitation in metal polyester fills. They are used for inkjet inks, glass colouration and marking inks and in media industry and magazine. They are also used for signalling smoke in the pyrotechnics industry as well as in medical research and diagnostics and are used for component stains to help in the identification of various cell ultrastructures. The solvents are also used in wood stains, fibre and filaments, hydrocarbon fuels and waxes and also in the food industry.
