Let’s understand the chemical structure and importance of solvent colorants

Solvent dyes, as the name suggests these are non-polar in nature and have the solubility in organic solvents. This agent is used in wider application area.

For coloring material like waxes, ink, organic solvents, plastic materials, hydrocarbon fuels etc., the use of these dyes is immense. Its feature to color hydrocarbon-based nonpolar materials makes it the best dyes amongst coloring agents. It is also referred as solvent red, solvent yellow, green, and blue.

Apart from coloring agent, this is also termed as liquefying agent because of its feature that enables it to liquefy in other chemicals.

Another feature of solvent dye that sets it apart from rest of the others is its insolubility in water. This means the dye is mixed with water for obtaining results but it does not completely resolves into it. This formation of mixing of dye into water forms a separate layer of residuals.

The solubility feature of solvent dyes helps achieving fine and long lasting color shades, which is not present in any other coloring agent.

Moreover this coloring agent do not ionize, which means, solvent dyes are required going through molecular reorganization and lost their ability to ionize. During the process of ionization the polarity of chemical compound changes. This is because releasing or adding an electron during chemical reaction causes the polarity of chemical substance to change. Hence, this is the reason why these colorants are not soluble in water and falls into the category of high-polar substances.

The feature makes these solvent colorants optimal for making perfumed items. Besides this, these also easily react with non-polar chemicals such as oils, fuels, fats etc.

Following is detailed discussion about the areas in which solvent colorants are used-
  • Petrol & Fuel Oils
  • Cosmetics
  • Preparing wax & candles
  • Removing wood stain, and varnishes
  • Coating and copying papers
  • Coating typewriter ribbons
  • Rubber stereo printing
  • Color molding powders, PVC, P/F, U/F, PMMA, PETP, and styrene monomers
    Dye leather
  • Used in preparing aluminum foil printing, cellulose acetate, alkyd, nitrocellulose etc.
From the above stated points, you must have gained knowledge about the structure and use of dyes. If you are dealing in any of the industries that you must be requiring this dye. For purchasing it, you must contact a reliable chemical provider in the industry. The term reliable means one who is known for providing quality products.

What properties make Zinc Borate an optimal choice for different industries?

Zinc Borate also termed as ZB is an inorganic compound used by majority of industries. It is white crystalline, has 980 °C melting point, low vapor pressure, and its insoluble water properties make it an optimal choice for many industries.

In addition to these properties, its insoluble water factor with low toxicity in nature and melting point of 980 °C make it prime choice for many industries.

Following are the properties of this chemical that is commonly used by various industries-
  • Flame retardant- Many plastic, cellulose fibers, paper, rubbers, and textiles industry use this compound for their purpose because of its flame retardant feature.
  • Easily mixed with other compounds- Because of mixing quality factor of this compound, the paints, adhesives, and pigments industry does make use of this compound for their purpose.
  • Halogen free-Its flame retardant feature in conjunction with halogen-based and halogen-free properties makes it an optimal choice for various industries those requiring halogen for their industry purpose.
  • Anti-dripping and char-promoting agent- Many electrical insulator plastic companies use this chemical for conducting process like arcing and tracking.
  • Blending feature- Its chemical mixture property when used in conjunction with antimony trioxide and alumina trihydrate chemicals provides glass a protective layer thus optimal for use by plastic industries.
  • Protective feature- When used in conjunction with alumina trihydrate, magnesium hydroxide, red phosphorus, or ammonium polyphosphate, the chemical provides a protective feature to the plastics when burnt for making different things.
  • Extensive chemical property- ZB when combined with chemicals like polyvinyl chloride, polyolefin, polyamides, epoxy resins, polyesters, thermoplastic elastomers, and rubbers make it optimal for use in intumescent systems.
  • Synergistic effect- Zinc phosphate or barium borate is blended with ZB to create a corrosion inhibitor pigment for its wide use of application in many industries.
  • Help reduce fungicide- Plastics and wood products often get fungicide. To reduce fungicide effect on products, borate of Zinc is used by many wooden application industries.
In addition to these properties, the lubricating feature and vast other properties make it optimal choice for use in ceramic application industries.
