Difference Between Pigments And Dyes

Pigments and dyes are considered as the major industrial colorants employed

across industries for various purposes. The uses of these colorants in diverse

industries have augmented quickly in the recent years. Despite of this, there’s a

familiar confusion in distinguishing dyes from pigments. Generally, they’re

assumed to be the same. However, there’s a considerable difference between dyes

and pigments. Let’s have a look at the differences between pigments and dyes.

Pigments are the ground chunks of solid color which are blended up employing a

mixture that attaches the colorants to the base where it should be applied. They

embark inside surface irregularities, such as sanding marks and wood pores. The

materials with coarse surface particles receive more pigments comparative to those

with fine surface particles. This occurs because materials with fine surface

particles provide less room for colorants to slot-in.

Dyes, on the opposite, soften in their solvents absolutely. For this reason, the

colors of the particles of the base onto which dyes are being applied transforms

completely. This provides an evidently diverse look in contrast to pigments,

particularly on surfaces with fine particles. Today, dyes are accessible in a variety

of different forms including dry powders, chips, liquids, granules, pastes and

pellets.

Beside solubility, there’re a considerable number of limitations that can be

employed to illustrate the thin line dissimilarity between pigments and dyes. Light

fastness is 1 such parameter. Whilst dyes are susceptible to light beams falling over

them, pigments have strong resistance to light and don’t break down upon light

contact. For this reason dyes are ignitable whereas pigments are non-ignitable. In

terms of dimension, dye particles are tinnier than pigment particles. Pigments and

dyes are also different in terms of their durability; pigments last longer in

comparison to dyes. In addition, dyes are natural elements relative to pigments

which may be natural or synthesized chemically.

Due to these dissimilarities, the uses of pigments and dyes are totally different. To

produce a superior and more rewarding worth for your coatings, papers, plastics

and other specialties, picking the appropriate materials is very essential. If the

dissimilarities and their primary importance aren’t values then many mistakes can

happen while choosing the proper material, its appropriate treatment and

subsequent application.

Now you understand the different between dyes and pigments – it will be easier for

you to decide which industrial colors are best suited your need and select the

product accordingly.
